The photographic material comprises a support bearing, on one side thereof, a layer containing a light-sensitive silver halide emulsion comprised of silver halide grains having an average size of from 0.05 µm to 0.3 µm and gelatin and, on the other side thereof, a non-light-sensitive layer containing gelatin and at least one of the emulsion layer and the non-light-sensitive layer is brought into contact with air having a temperature of from 35°C to 80°C or a relative humidity of from 5% to 25% for a period not shorter than 5 seconds to not longer than one minute, within 5 minutes from the point of time when the average surface temperature of said layer is raised up to a temperature 1°C lower than the average temperature of the atmosphere for drying said layer in the step where said layer is coated on said support and is cooled as to be gelled and dried. The photographic material is processed within the range of from 20 seconds to 60 seconds.

Description: FIELD OF THE INVENTION This invention relates to a silver halide photographic light-sensitive material, a method of preparing the same and a method of forming an image by making use of the same and. more particularly, to a graphic arts light-sensitive material excellent in dimensional stability, hard contrast characteristics and rapid processing aptitude. BACKGROUND OF THE INVENTION In recent years, the consumption of silver halide photographic light-sensitive materials is being increased year by year. The number of processing silver halide photographic light-sensitive materials are accordingly getting increased, so that there have been demanded for making processing time more rapid, in other words, for increasing the number of processing more within a fixed time. In graphic arts fields, there is also the same tendency. To be more concrete, now that real-time information and the frequency thereof are rapidly increased, it is required also in graphic arts field not only to complete an allotted work within a shorter time but also to do more jobs. To satisfy the above-mentioned demands of the graphic arts industry, it is required to simplify printing steps and, at the same time, to process each graphic arts film more rapidly. To shorten the processing time comprising the time required for the processing steps such as those of develoing, fixing, washing and drying, one of the answers is to increase the transport speeds through the steps. However, in the case of processing a film with a roller transport type automatic processor and when a roller transport speed is so accelerated as to shorten the film processing time, there will raise such a trouble that the drying step is not satisfactorily performed, because the drying time is too short. As for the methods for processing films in a short time, there are some methods, namely, one of the methods is to raise a temperature in the course of drying films in an automatic processor, another method is to increase the flow rate of the air coming into contact with a silver halide photographic light-sensitive material, and a further method is to reduce a gelatin content of a light-sensitive material. When drying films in the above-mentioned methods, there will cause such a serious defect that the length of a processed photographic image will become longer than that before it is processed. This defect is so-called a dimensional stability difference between pre-processing and post-processing dimensions. Particularly, in the fields of graphic arts handling color printing, there will cause the troubles such as that the plate dimensions of four colors, yellow, mgenta, cyan and black, will not be coincident with each other. It may be considered that these defects may be derived from the change of the silver halide emulsion of a silver halide photographic light-sensitive material into silver atoms or the elution of the emulsion from the light-sensitive material and the hysteresis of gelatin. Besides the above-mentioned troubles, another problem will result from increasing the concentration of a sulfur-containing salt in a processed film so as to change the color of the processed film into yellow during storage, because the fixing and washing time are shortened. A further problem will result from making a density lower even if raising the development activity of a developer and the temperature thereof so as to adjust the sensitivity to the original, because the development time is shortened. As for the means for solving these problems, there may be a means that the grain sizes of silver halide of a light-sensitive material are made smaller. However, a problem will result from remarkably deteriorating the aforementioned dimensional stability difference between pre-processed and post-processed films, when the grain sizes are made smaller to a certain extent. As described above, a superrapid processing has been demanded. The term, a 'superrapid processing' stated herein means a process in which the whole period of time from inserting the leading edge of a film into an automatic processor until the leading edge of the film comes out from a drying section of the processor through a developing tank, a cross-over section, a fixing tank, a cross-over section, a washing tank, a cross-over section and a drying section, respectively, (in other words, the whole period of time means a quotinent of the total length (in meter) of a processing line divided by a line transport speed (in meter/second), the period is within the range of from 20 sec. to 60 sec. The reason why the period of cross-over should be included therein is that a gelatin layer being transported through a cross-over section is pregnant with the liquid used in the preceeding processing step and thereby the processing may be regarded as is still being substantially progressed, of which has been well known in the art. In addition to the above, there are the methods for inhibiting the dimensional change of light-sensitive materials, by adding a hydrophilic colloidal layer with such a latex as those disclosed in, for example, Japanese Patent Examined Publication Nos. 39-17702 (1964), 39-24142 (1964), 43-13482 (1968) and 45-5331 (1970); U.S. Patent Nos. 2,376,005, 2,763,625, 2,772,166, 2,852,386, 2,853,457, 3,397,988, 3,411,911 and 3,411,912, and so forth. They are, however, not only unsatisfactory to display any effect, but also have the defect that an image density lowering is further multiplied after processed in the aforementioned superrapid processing. Meanwhile, when processing a silver halide photographic light-sensitive material with a roller-transport type automatic processor, the density of a photograph and the dot quality thereof will be deteriorated when accelerating a roller-transport speed and shortening a developing time. To compensating these deteriorations, there are a method of increasing the activity of a developer and another method of raising the temperature of a developer. However, these methods generally have the defects that fog will be increased, dots will be coarse-grained or faded out in edge portions. Taking a high quality finishing having been recently demanded by the graphic arts field into consideration, such a simple high temperature rapid process as above-mentioned is not preferable. Accordingly, it has been demanded to provide a super-rapid processable photographic light-sensitive material having both of a highly finished quality and a high dimensional stability. SUMMARY OF THE INVENTION It is an object of the invention to provide a silver halide photographic light-sensitive material without damaging any photographic characteristics and having an excellent dimensional stability both before and after processing even when the light-sensitive material is processed and dried with, for example, an automatic processor, and to provide a method for preparing the light-sensitive material. Another object of the invention is to provide a silver halide photographic light-sensitive material capable of solving the aforementioned problems derived from the conventional art even when carrying out the above-mentioned super-rapid process, for example, which takes a period of time from 20 sec. to 60 sec. for the whole processing step, and having excellent operational speed, dimensional stability, reverse plate making and dot quality as well as few fogginess, and also to provide the method for preparing the same. These and other objects of the invention will become apparent from the following detailed description. The objects of the invention can be achieved by the use ofa method for preparing a silver halide photographic light-sensitive material, which comprises a support bearing, on one side thereof, a layer containing a light-sensitive silver halide emulsion comprised of silver halide grains having an average size of from 0.05 to 0.3 micro-metres and gelatin, and on the other side thereof, a non-light-sensitive layer containing gelatin, comprising the steps of coating said layer containing said emulsion or said non-light-sensitive layer on a support, bringing said coated layer into contact with air having a low temperature to cool and gel the layer, blowing air at the layer until the average layer surface temperature of said layer is raised up to a temperature 1°C lower than the average temperature of atmospheric air for drying said layer, characterised in that within 5 minutes from the point of time when said average temperature of said gelled and dried layer is 1°C below the average temperature of the drying air the layer is brought into contact with air at a temperature of from 35° to 80° C or a relative humidity of from 5% to 25% for a period not shorter that 5 seconds to not longer that one minute. The effects of the invention can be displayed more excellently when the light-sensitive material of the invention is brought into contact with the air substantially having a dew-point of not higher than 16°C in the course of the steps from the point of time when the coating and drying steps are completed that is the point of time when completing the coating and drying processes for both of sides of the light-sensitive material to the point of time when the light-sensitive material is completely packaged. In addition to the above, a silver halide photographic light-sensitive material having a polymer latex content of from 0.1 g/m² to 10 g/m² in at least one of the hydrophilic colloidal layers provided to at least one side of the support, such light-sensitive material can be further improved on the pre-processing and post-processing dimensional stabilities by applying the above-mentioned drying process. In this patent specification, the words, 'dimensional stability', means difference of dimensions between a pre-processing and post-processing. BRIEF DESCRIPTION OF THE DRAWING Figure 1 is a cross-section of a film transport mechanism. DETAILED DESCRIPTION OF THE INVENTION Coating and drying conditions for preparing a light-sensitive material are usually applied in such a manner that a coating solution comprising a gelatin composition is coated over to a support and is then generally so cooled down as to be solidified in the air having a low dry-bulb temperature of from -10 to 15°C and the resulting coated layer is then dried by raising the temperature. However, such a high temperature drying as mentioned above aims at making a drying rate faster and, therefore, at the point of time when the drying is completed, the air temperature having been contacted with the coated layer is usually restored to an ordinary temperature. In the invention, a silver halide photographic light-sensitive material is brought into contact with the air having a temperature of from 35°C to 80°C for a period of from not shorter than 5 sec. to not longer than 1 min. within 5 min. from the point of time when the average temperature of the coated layer surface is raised up to a temperature 1°C lower than the average temperature of the atmospheric air for drying the coated layer in the preparating steps where at least either one of the coated layers is coated and the gelatin of the layer is so cooled down as to be gelled and dried. The expression, 'the point of time when the average temperature of a coated layer surface is raised up to a temperature 1°C lower than that of the air coming into contact with the layer' stated herein corresponds to the point of time when the moisture content of a gelatin composition is within the range of from 60% to 20%, that may be regarded as the point of time when the drying step may substantially be completed. In other words, a light-sensitive material is brought into contact with the air having a temperature of from not lower than 35°C to not higher than 80°C for a period from 5 sec. to not longer than 1 min from the above-mentioned point of time. This fact results in excellently improving a dimensional stability, assuming that a synergetic effect of both silver halide grain sizes and this fact may be displayed. The contact of a light-sensitive material with the above-mentioned air having a temperature of from not lower than 35°C to not higher than 80°C corresponds to the contact of the light-sensitive material with the air having a relative humidity of from 25% to 5%. The same effects can also be enjoyed in the invention in which a light-sensitive material is brought into contact with the air having a relative humidity of from 25% to 5%. This kind of effects cannot be displayed when processing a light-sensitive material in the range of a moisture content of not less than 60% while bringing the light-sensitive material into contact with the air having a temperature within the range of from 35°c to 80°C. Further, in this kind of processes, it has been well known in the art that many pin-holes are produced by moving a matting agent from a surface layer into gelatin. In the invention, it is hard to cause this kind of troubles. In this specification, the point of time when a light-sensitive material is brought into contact with the air having a temperature of from 35°C to 80°C or the air such as dried air blow having a relative humidity of from 25% to 1% in the above-mentioned process, such a point of time is hereby defined as the point of time when a coating and drying process is completed. In a coating and drying process where the drying requirements of the invention is not carried out, the above-mentioned point of time is defined as the point of time when a coated light-sensitive material passed through a drying zone. The methods for adjusting a relative humidity to be within the range of from 25% to 5% include, for example, a method of raising a temperature of the air coming into contact with a light-sensitive material, another method of lowering an absolute moisture content of the air coming into contact therewith by making use of a dehumidifier and a combination method of the above-mentioned two methods. From the results of a further study. the inventors have found that the dimensional stabilities relating the processing can be improved more than before when applying the drying requirements of the invention to a silver halide photographic light-sensitive material containing polymer latex in an amount of from 0.1 g/m² to 10 g/m² in at least one hydrophilic colloidal layer arranged to at least one side of a support. Such a silver halide photographic light-sensitive material containing the above-mentioned polymer latex has showed an excellent surface property without causing any cracks on the surface of the light-sensitive material, even when it is exposed to the air having a very high temperature and a very low humidity in the drying conditions. It is effective to bringing a light-sensitive material into contact with the air relating to the invention at the point of time when completing a drying process. For example, when coating and drying each coated layer provided on both sides of a support one after another, it is effective when at least either one of the coated layers is treated at the above-mentioned high temperature in its coating and drying processes. It is more preferable that the both layers are treated at a high temperature in their coating and drying processes. When shipping thus manufacture silver halide photographic light-sensitive materials as the merchandise, the effects of the invention can effectively be displayed particularly when carrying out the steps from the completion of coating and drying both sides of the light-sensitive material to the completion of packaging it in the circumstances where a dew-point temperature is not higher than 16°C. Another object of the invention can be achieved when a silver halide photographic light-sensitive material has a gamma (γ) of not lower than 6 specified with respect to a density of from 0.3 to 3.0, in the aforementioned drying requirements. From the results having been obtained by the repeated studies, the inventors have further found that, in a photographic light-sensitive material having hard contrast photographic characteristics such as a γ value of not lower than 6 specified with respect to a density of from 0.3 to 3.0, such a light-sensitive material can display a furthermore excellent dimensional stability as it still remains excellent in property in reproduction of line width in multiple layer contact work and dot quality as well as low in fogginess. The synergistic effects of the photographic characteristics and the dimensional stabilities have not so far been known at all in the conventional art. Now, the invention will be described in further detail. In the invention, the above expression, 'the air for drying a light-sensitive material', hereby means the air with which the light-sensitive material is brought into contact and so supplied as to blow directly on the light-sensitive material for the purpose of drying it or adjusting its moisture content. Thus defined air does not mean the air present in the space between the surfaces of rolled light-sensitive material which has been coated and dried or between the surfaces of light-sensitive materials which have been cut into a desired size and piled up. The expression, 'the steps from the point of time when completing a coating and drying process to the point of time when completing a packaging' stated herein include such a step as those of taking up, cutting and packaging a light-sensitive material and, sometimes, those steps include such a process as those of storing and transferring it. In the specification, the expression, 'the air to be brought into contact with ---', stated herein means 'the air being brought into contact with a light-sensitive material in such a state that the light-sensitive material comes into contact with nothing but the air. In most cases for transferring a light-sensitive material, it is taken up to be in the rolled form, i.e., in a bulk, or it is cut into a desired size and then piled up. In the case of a bulk, for example, it may be considered that the air in the circumstances where the bulk is placed does not substantially come into contact with the portion of the bulk where a light-sensitive material comes into contact on the both sides thereof with other light-sensitive materials. In other words, for example, in the case where, after completing the coating and drying process of the invention, a light-sensitive material is brought into contact with the air having a dew point of not higher than 16°C and is then taken up to be in the form of a roll, and the rsulting bulk roll is transferred through the air having a dew point of not higher than 17°C and then cut into a desired size and packaged while coming into contact again with the air having a dew point of not higher than 16°C, such a case shall also be included in the preferred embodiments of the invention. In the invention, on one side of a support, light-sensitive silver halide grains having an average grain size of from 0.05µm to 0.3µm are used. The term, an 'average grain size', herein means an average diameter of the grains in the case of globular-shaped grains and an average diameter of the circular images having the same areas as those of the images projected from the grains in the case of the other shaped grains than the globular-shaped ones. It is preferable that not less than 60% of the total number of grains should have a grain size within the range of plus or minus 10% of an average grain size. The silver halide emulsions applicable to the invention, hereinafter sometimes called the silver halide emulsions or simply the emulsions, are allowed to use any of silver halides which may be used in an ordinary types of silver halide emulsions, such as silver bromide, silver iodobromide, silver iodochloride, silver chlorobromide, silver chloride and so forth. Among them, it is preferable to use silver chlorobromide containing silver chloride in a proportion of not less than 60 mol% to serve as a negative type silver halide emulsion and to use silver chlorobromide, silver bromide or silver iodobromide each containing silver bromide in a proportion of not less than 10 mol% to serve as a positive type silver halide emulsion. The silver halide grains applicable to the silver halide emulsion may be any of those prepared in an acidifying method, a neutralizing method, an ammoniacal method or the like methods. Those grains may be grown up at a time or may be grown up after preparing seed grains. The processes of preparing the seed grains and the processes of growing them may be either the same with or the different from each other. The silver halide emulsion may also be prepared by mixing silver halide ions and silver ions together at the same time or by mixing either one of the ions in a liquid containing the other. In addition, the emulsion may be prepared by adding halide ions and silver ions gradually and at the same time while controlling the pH and pAg of a mixture solution, taking the critical growth rate of silver halide crystals into consideration. According to this preparation process, silver halide grains regular in crystal form and nearly uniform in grain size may be prepared. After growing the grains, the halide compositions of the grains may be varied in a conversion method. When preparing silver halide emulsions, if required, it is allowed to control the grain size, grain configuration, grain distribution and grain growth rate each of the silver halide grains by making use of a silver halide solvent. Silver halide solvents include, for example, ammonia, thioether, thiourea, thiourea derivatives such as quadri-substituted thiourea, imidazole derivatives. For the details of thioether, U.S. Patent Nos. 3,271,157, 3,790.387, 3,574,628 and so forth. Such a solvent may be used in a proportion of a reactant solution of from 10⁻³ to 1.0 wt% and, preferably, from 10⁻² to 10⁻¹ wt% in the case of other solvents than ammonia, and any amount may be used in the case of ammonia. The silver halide grains applicable to the silver halide emulsions are allowed to be added, in the courses of forming the grains and/or growing them, with metal ions by making use of at least one kind of metal salts selected from a group consisting of the salts of cadmium, zinc, lead, thallium, iridium including the complex salts thereof, rhodium including the complex salts thereof and iron and the complex salts thereof, so as to contain the metal element of the above-given metal salts in the inside and/or surface of each grains. Particularly, it is preferable to contain a water-soluble rhodium salts therein. A reduction sensitization nucleus may be provided to the inside and/or surface of a grain by making an atmosphere appropriately reducible. When adding a water-soluble rhodium salt, it should be preferable to add in an amount of from 1x10⁻⁷ to 1x10⁻⁴ mol per mol of AgX. After completing the growth of silver halide grains, unnecessary soluble salts may be removed from the silver halide emulsions or may be allowed to remain contained therein. When removing the salts, it is allowed to follow the removing method described in, for example, Research Disclosure, No. 17643. The silver halide grains applicable to the silver halide emulsions may be either those having a uniform silver halide composition distribution therein or core/shell type grains having the silver halide compositions which are different between one inside the grains and the other in the surface layer thereof. The silver halide grains applicable to the silver halide emulsions may be either those capable of forming a latent image on the surfaces of the grains or those capable of forming it inside the grains. The silver halide grains applicable to the silver halide emulsions are allowed to have either regular crystal forms such as a cube, an octahedron and a tetradecahedron orirregular forms such as a globular-form and tabular-form. In these grains, any ratios of {100} face to {111} face may be used. Those grains may be not only in the complexed crystal forms but in various forms. In order to serve as the silver halide emulsions, it is allowed to use the mixture of two or more kinds of silver halide emulsions separately prepared. The silver halide emulsions may be chemically sensitized in any ordinary methods, namely, a sulfur sensitizing method, a selenium sensitizing method, a reduction sensitizing method, a noble-metal sensitizing method in which gold or other noble metals are used, or the like methods, independently or in combination. It is preferable to sensitize the silver halide emulsions in the sensitizing methods with the sensitizers described in, for example, British Patent Nos. 618,061, 1,315,755 and 1,396,696; Japanese Patent Examined Publication No. 44-15748 (1969); U.S. Patent Nos. 1,574,944, 1,623,499, 1,673,522, 2,278,947, 2,399,083, 2,410,689, 2,419,974, 2,448,060, 2,487,850, 2,518,698, 2,521,926, 2,642,361, 2,694,637, 2,728,668, 2,739,060, 2,743,182, 2,743,183, 2,983,609, 2,983,610, 3,021,215, 3,026,203, 3,297,446, 3,297,447, 3,361,564, 3,411,914, 3,554,757, 3,565,631, 3,565,633, 3,591,385, 3,656,955 3,761,267, 3,772,031, 3,857,711, 3,891,446, 3,901,714, 3,904,415, 3,930,867, 3,984,249, 4,054,457 and 4,067,740; Research Disclosure, Nos. 12008, 13452 and 13654; T.H. James, 'The Theory of the Photographic Process', 4th ed., Macmillan. 1977, pp. 67-76; and so forth. The hard contrast photographic characteristics having a γ value of 6.0 which is specified with respect to a density of from 0.3 to 3.0, that is one of the preferable embodiments of the invention, may be applied to both of the negative and positive types light-sensitive materials. It is particularly preferable to prepare a negative type of light-sensitive material in such a process that a tetrazolium, hydrazine or polyalkylene oxide compound is contained in at least one of the hydrophilic colloidal layers each containing a light-sensitive silver halide emulsion and/or in the adjacent layers each constituting the negative photographic light-sensitive material. The light-sensitive material is processed with a developer containing hydroquinone only or hydroquinone-phenidone or hydroquinone-metal as developing agent and having a pH of from 10 to 13.

It is also allowed to finely disperse the resulting solution in such a high boiling solvent as dioctyl phthalate or the like so as to be protected form and the resulting fine dispersion is dispersed in a hydrophilic colloidal layer. Next, referring to a method in which a hard contrast negative image is obtained by processing a negative type silver halide photographic light-sensitive material containing a hydrazine derivative that is a specific acylhydrazine compound including, for example, those given in, U.S. Patent Nos. 4,166,742, 4,168,977, 4,221,857, 4,224,401, 4,243,739, 4,272,606 and 4,311,781, by making use of a solution containing a sulfite preserving agent in an amount of 0.15 mol/liter at a pH of from 11.0 to 12.3, (The above-mentioned method is hereinafter referred to as the hydrazine hard-contrast developing system.) The examples of the hydrazine derivatives applicable to the above-mentioned system include arylhydrazides each having a sulfinic acid residual group bonded to the hydrozo portion thereof disclosed in U.S. Patent No. 4,478,928 and, besides, the compounds each represented by the following Formula III.

The hydrazine derivatives represented by the above-given Formula III are disclosed in Japanese Patent O.P.I. Publication No. 62-210458 (1987), and the exemplified compounds given in the same publication may also be applicable to this invention.

In the invention, when containing a hydrazine derivative in a photographic light-sensitive material, it may be added in the form of an aqueous solution if it is water-soluble. If the hydrazine derivative is water-insoluble, it may be added in either a silver halide emulsion solution or a hydrophilic colloidal solution after it is made be in the form of an organic solvent solution capable of being soluble in water, including, for example, those comprising alcohols such as methanol or ethanol, esters such as ethyl acetate, ketones such as acetone or the like. In the invention, the hydrazine derivative may be used either independently or in combination. It has been known to apply a method using a polyalkylene oxide compound to lith-type photographic light-sensitive materials. Besides the above, there is also a well-known system for obtaining a hard contrast image in sumch a manner that the lith-type silver halide light-sensitive material is processed with a hydroquinone developer, namely, a developer containing a nitroindazole type compound and having a considerably high sulfurous acid ion concentration of not lower than 0.2 mol per liter and a high pH of not lower than 10.5. This system is disclosed in Japanese Patent O.P.I. Publication No. 58-190943 (1983) and is hereinafter called a rapid lith processing technique. Next, the polyalkylene oxide compounds applicable to the rapid lith processing technique will be described below.

In the latter case, it is allowed that the individual polyalkylene oxide chains each have less than 10 alkylene oxide units, provided however that the total number of alkylene oxide units contained in a molecule should be ten. In the case where a molecule has two or more polyalkylene oxides, it is allowed that the alkylene oxides may have the different alkylene oxide units from each other units, such as a combination of an ethylene oxide and a propylene oxide. The polyalkylene oxide compounds applicable to the invention preferably contain the number of the alkylene oxide units of from not less than 14 to 100 units.

These dyes may be applied with any nuclei which are usually applied to cyanine dyes, to serve as the basic heterocyclic nuclei. These heterocyclic nuclei include, for example, those of pyrroline, oxazoline, thiazoline, pyrrole, oxazole, thiazole, selenazole, imidazole, tetrazole and pyridine, and nuclei each having an alicyclic hydrocarbon ring being held molten into the aforegiven nuclei, such as those of indolenine, benzindolenine, indole, benzoxazole, naphthoxazole, benzothiazole, naphthothiazole, benzoselenazole, benzimidazole, quinoline or the like. These nuclei may be substituted on carbon atoms.

Exemplified Compounds The desensitizing dyes relating to the invention are selectively used in an amount of, preferably, from 1 mg to 1,000 mg per mol of silver halide used and, more preferably, from 5 mg to 300 mg. They may be added at any points of time, such as a time when a silver halide is produced or a physical or chemical ripening is being carried out, after the ripening is completed, or a time when a coating solution is being prepared. It is desirable that the desensitizing dyes of the invention have a sensitivity of not higher than 450nm so as to prevent the sensitivity from being lowered and a maximum wavelength of spectral sensitivity of not less than 500nm. Any light-sensitive materials of the invention can be exposed to light by making use of electromagnetic waves of a spectral wave region to which the emulsion layers of the light-sensitive material are sensitive. As for the light sources applicable for this exposure, any of the well-known light sources may be used. They include, for example. natural light, i.e., daylight, a tungsten lamp. a fluorescent lamp, an iodine-quartz lamp, a mercury lamp, a microwave-emitting UV lamp, a Xenon-arc lamp, a carbon-arc lamp, a Xenon-flash lamp, flying spot by a cathode-ray tube, a variety of laser beams, a light-emmitting diode, light emitted from a phosphor excited by electron-, X-, γ- or α-rays, and so forth. Particularly, with a light-sensitive material of the invention having a maximum sensitivity to a light of not more than 450nm, even when the light-sensitive layer thereof is exposed imagewise to light of not substantially lower than 370nm, a preferable result may be obtained. In a roomlight contact type light-sensitive material, it is particularly preferable that the sensitivity to light of 400nm should be not less than 30 times higher than the sensitivity to light of 360nm. Next, the methods for 'exposing imagewise a light-sensitive layer to light of substantially not lower than 360nm′ include, for example, a method in which a UV absorbing agent is contained in a light-sensitive material, another method in which an optical filter is used for absorbing UV rays, a further method in which a light source not having substantially any light-emmission energy of not higher than 370nm is used, and so forth. Now, the first-mentioned method will be described. As for the UV absorbing agents, a substance capable of reducing the inheric sensitivity of a silver halide emulsion to be not more than one half, that is a UV absorbing agent having a peak of from 300 to 400nm and, more preferaly, from 300 to 380nm. The UV absorbing agents applicable thereto include, for example, a benzotriazole compound, a 4-thiazolidone compound, a benzophenone compound, a cinnamic acid ester compound, a butadiene compound and a benzoxazole compound each substituted with an aryl group, and a UV absorbing agent polymer. The typical examples of the UV absorbing agents are described in U.S. Patent Nos. 3,533,794, 3,314,894 and 3,352,681, Japanese Patent O.P.I. Publication No. 46-2784 (1971), U.S. Patent Nos. 3,705,805, 3,707,375, 4,045,229, 3,700,455 and 3,499,762, West German DAS Patent Nos. 1,547,563, and so forth. In the invention, it is allowed to use the typical compounds given in Japanese Patent O.P.I. Publication No. 62-210458 (1987). In the invention, the UV absorbing agent is so added as to reduce the inheric sensitivity of a silver halide emulsion to be not more than one half. They are to be added in such an amount that the absorptivity may become not less than 0.3 at 360nm and, more preferably, not less than 0.4 at 360nm. An amount added depends on the molar absorptivities of UV absorbing agents. However, they are usually added within the range of from 10⁻² g/m² to 1 g/m² and, more preferably, from 50 mg/m² to 500 mg/m². The UV absorbing agents of the invention are contained in an emulsion layer, a surface protective layer, an interlayer and so forth. It is allowed to add the above-mentioned UV absorbing agents in the coating solution for a non-light-sensitive hydrophilic colloidal layers of the invention, after they are dissolved in an appropriate solvent such as water, alcohol including methanol, ethanol, propanol or the like, acetone, methyl cellosolve and so forth or the mixtures thereof. It is also allowed to use these UV absorbing agents in combination. In the invention, the above-mentioned safelight dyes and the UV absorbing agents may be present together in one and the same layer or in the different layers separately. Now, the second method will be described. the UV absorbent optical filters, i.e., filters for light-sources, applicable to this method include, preferably, a filter almost incapable of trasmitting rays of light having 370 nm or lower, such as Acrilite AR-1001 manufactured MITSUBISH Rayon Co., thickness 4 mm. To be more concrete, the transmissivity of these filters should preferably be not higher than 20% and, more preferably, be not higher than 10%. Next, the third methd will be described. Lhe light sources themselves substantially not having a light emission energy in the areas of not higher than 370nm include, for example, those sold under the trade names; 'EYE DOLPHIN' manufactured by EYE GRAPHICS Co., Ltd.; a light source for Graphic art printer P-603 manufactured by Dainippon Screen Mfg. Co., Ltd.; a metal halide lamp Type SPG-2000 (2KW) manufactured by Japan Storage Battery Co., Ltd.; and so forth. As for the light sources applicable to the third method, those having a light emission energy of not higher than 30% in the area from 300nm to 370nm among the aforespecified area of from 300nm to 420nm may preferably be used and those having the energy of not higher than 20% may more preferably be used. It is further allowed that roomlight processable light-sensitive material emboding the invention can be exposed to a light source having a higher intensity than those of the conventional room light sources through a UV-absorbing optical filter for light sources. Those high-intensity light sources applicable thereto include, for example, an ultra-high pressure mercury vapour lamp, H-15-L31 (15KW), manufactured by EYE GRAPHICS Co., Ltd., and so forth. When exposing a light-sensitive material to a light source by interposing a UV-absorbing optical filter for light sources between the light-sensitive material and the light source, the conventionally known light sources may be used for such a purpose that a layer containing a UV absorbing agent or the like is provided into a light-sensitive material so that the rays of light substantially not containing the rays of light of not more than 370nm may reach a light-sensitive layer, or for the like purposes. Such light sources as mentioned above include, for example, the light source for the graphic art printer, P-607, that is, an ultra high pressure mercury vapour lamp URT-CHM-1000 manufactured by Dainippon Screen Mfg. Co., Ltd., the light source for P-627FM manufactured by the same company, and so forth. For the light-sensitive material for contact printing of the invention, the exposure time may be selected according to the intensity of a light source used, the sensitivity including the spectral sensitivity of a light-sensitive material used and so forth. It is usually exposed for a period of from 60 seconds to 5 seconds. In some case, it is allowed to expose it for such a long time as 2 to 3 minutes. The invention can be applied to a variety of light-sensitive materials such as those for graphic arts, X-rays, general negative images, general reversal images, general positive images, direct positive images and so forth. When the invention is applied to graphic art light-sensitive materials which require a very high dimensional stabilities between pre- and post-processing, the particularly remarkable effects can be enjoyed. In the invention, a light-sensitive material can be processed in well-known methods including, for example, a variety of developing processes such as black-and-white, color, reversal or the like processes. The invention is particularly effective when processing a graphic art light-sensitive material capable of providing a high contrast. When a tetrazolium or hydrazine compound is used as the hardening agent, a particularly preferable effect may be obtained by processing with a PQ or MQ type developer containing a sulfite in an amount of not less than 0.5 mol/liter at a pH of from 10.0 to 12.9. When a polyalkylene oxide compound is used as the hardening agent, a preferable effect can also be obtained by processing with a lith type developer as same as with the above-mentioned PQ and MQ type developers. The invention shall not be limited to the above-mentioned combination. In the invention, the fixing solutions applicable to the treatments of a light-sensitive material are allowed to contain a variety of acids, salts, fixation accelerators, wetting agents, surface active agents, chelating agents, hardening agents as well as thiosulfates and sulfites.

Finally, 144 g of glyoxal was added and water was then added to make 960 liters of the backing layer coating solution B-1. wherein m : n = 1 : 1 Next, Protective layer coating solution P-2 for coating a protective layer of a backing layer was prepared in the following manner. Preparation of Protective Layer Coating Solution P-2 The coating solution P-2 was prepared in the following manner. Gelatin of 50 kg were swollen in water and dissolved together with heating, Then. 340 g of sodium salt of 2-sulfonate-succinic acid bis(2-ethylhexyl)ester were added and 1.7 kg of polymethyl methacrylate having an average particle size of about 0.4µm as a matting agent and 3.4 kg of sodium chloride were added. Further, 1.1 kg of glyoxal and 540 g of mucochloric acid were added. Water was so added as to make 1000 liters of the protective layer coating solution P-2. Preparation of Samples for Evaluation use Each of the foregoing coating solutions was coated, in combination shown in Table-1, on one side after another of both sides of a 100µm-thick polyethylene terephthalate film support provided thereto with such an under-coat layer as described in Example-1 of Japanese Patent O.P.I. Publication No. 59-09941 (1984). so that each of the samples for evaluation use was prepared. In this preparation process, on one side of the support was coated with the backing layer coating solution B-1 so that the dry-weight of gelatin could be 2 g/m² and, on the B-1-coated layer was simultaneously coated with a backing protective layer by making use of the protective layer coating solution P-2 so that the dry-weight of gelatin thereof could be 1 g/m², and dried. Next, on the other side of the support was coated with an emulsion layer so that the dry-weight of gelatin could be 1.8 g/m² and the amount of silver coated could be 4.3 g/m² and, on the resulted emulsion layer was simultaneously coated with an emulsion protective layer by making use of a protective layer coating solution so that the dry weight of gelatin could be 0.8 g/m², with adding formalin as a hardening agent, and dried. The resulted sample material was cut up in the conditions at 23°C and 35%RH at a dew-point of 6°C and was then air-tight wrapped with a non-air-permeable wrapping paper, so that Evaluation Samples No. S-1 through No. S-10 were prepared respectively. The drying conditions thereof are shown in Table-2 below. Drying Conditions in Coating Process A 35°C-coating solution was coated on and then treated for 6 seconds by blowing the 5°C-air so that the solution was cooled down and set. Then, the resulted coated layer was dried with keeping the temperature of the coated layer surface at 10°C by blowing the dry air having a dry-bulb temperature of 23°C and a relative humidity of 20%, so as to make gelatin have a moisture content of 1600%. Next, the coated layer was dried by blowing the dry air having a dry-bulb temperature of 27°C and a relative humidity of 20%. Further, the coated layer was dried so that an average temperature of the dried coated surface could be at 33°C by blowing the dry air having a dry-bulb temperature of 34°C and a relative humidity of 43%. Five seconds later, the combinations of a, b, c, d, e and f were processed respectively under the conditions that a heat transmission coefficient of 100 kcal/hy.m² and the processing time for 40 seconds. The resulted samples, were unpacked under the conditions of an environmental temperature of 23°C and environmental relative humidity of 40% and were rehumidified for 12 hours. After then, they were subjected to the following dimensional stability test respectively. Dimensional Stability Test Thus rehumidified samples were scarred at intervals of 560mm at an environmental temperature of 23°C and relative humidity of 40%. The scarred samples were processed with an automatic processor under the following processing conditions by making use of the following developer and fixer. The structure of the automatic processor is shown in Fig. 1, wherein reference numerals indicate the following items, respectively; 1 is an inserting table, 2 is a detecting-developing cross-over rack, 3 is a developing rack, 4 is a developing-fixing cross-over rack, 5 is a fixing rack, 6 is a fixing-washing cross-over rack, 7 is a washing rack, 8 is a squeezing rack, 9 is a drying rack, 10 is a guide member, 11 is a drying-and-delivering rack, and 12 is a film receiving basket. Thus processed samples were rehumidified for 12 hours under the conditions of an environmental temperature of 23°C and relative humidity of 40% and the actual lengths of the scars left on the samples were then measured. Each value obtained by deducting the actual length of each scar from the aforegoing 560mm was regarded as a value of dimensional stability in terms of µm unit. A positive value thereof means that a sample was lengthened by the automatic processing. The more a sample is lengthened, the more a dimensional stability is lowered. The results are shown in Table-3. Processing solutions and conditions use in the test were as follows. Composition of Developers Developer A Composition A Before using the developer, Composition A and B were dissolved in order in 500 ml of water to make one liter and the resulted developer A was then used. Composition of Fixer Composition A Before using, the abvove-given composition A and B were dissolved in order in 500 ml of water to make one liter and the resulted fixer was than used. The pH of this fixer was about 4.3. Processing conditions Heat transmission coefficient of a dryer: 95 kcal/hr.m².C° Environmental temperature and relative humidity of an automatic processor installed: 23°C and 40%RH The processing time of each processing step includes the time required for transporting film through the so-called cross-over sections between the respective processing steps. Time required for dry-to-dryl: 85 seconds Line speed: 1500mm per minute As is obvious from the results shown in Table-3, an excellent dimensional stability cannot be provided unless an average grain size of silver halide is not larger than 0.3µ and, at the same time, the drying conditions, b, c, d, e or f corresponding to the conditions of the invention are applied. It is found that, when an average grain size of silver halide is 0.4µ, any effect cannot be observed even if the drying conditions are changed and the dimensional stability is also deteriorated. When applying the coating and drying conditions to a backing layer side or an emulsion layer side, that is, in the cases of S-5 or S-6 and S-8, a good effect can also be enjoyed. However, the most excellent results can be obtained when applying the drying conditions of this embodiment to both of the emulsion side and the backing side, that is, in the cases of S-7 and S-9. Example-2 The following samples were prepared by applying the same drying conditions as in Example-1, except that the polymer latex contents of the coating solution E-2 of Example-1 were changed, and thus prepared samples were subjected to the same dimensional stability test as that tried in Example-1. Further, the transmission density of each sample was measured by making use of a Konica Densitometer, PDA-65, in such a manner that the samples were exposed to light for 8 seconds with bringing the emulsion side of each sample into close contact with the glass plate of a roomlight type printer, P-627FM manufactured by Dainippon Screen Mfg. Co., and process in the aforementioned manner. As is obvious from Table-4, it can be observed that the samples each containing polymer latex, e.g., S-17, S-18 and S-19, are more excellent in dimensional stability than the samples each not containing any of them, e.g., S-16, and that the samples containing the same in an amount of exceeding 10 g/m², e.g., S-19, are lower in density than the samples, e.g., S-16, S-17 and S-18. Example-3 In this example, positive type silver halide light-sensitive material were prepared in the following manner. An aqueous gelatin solution having a pH of 2 and having been kept at 55°C was mixed with both of an aqueous gelatin solution containing a sodium hexachlororhodate in an amount of 25 mg per mol of silver and 2.5 mols of potassium bromide and an aqueous solution containing 2.5 mols of silver bromide, by taking 70 minutes in a double-jet precipitation method, provided that an amount of ions was so adjusted as to satisfactorily growing the grains while controlling a silver electrode potential and a pH to keep at 140 mV and pH=2, respectively. At the time when the above-mentioned mixture was completed, the pH was adjusted to be 5.5 and water-soluble salts were removed in an ordinary coagulation method and, further, gelatin was added, so that a monodisperse type silver bromide emulsion having an average grain size of 0.2 µm was prepared. Preparation of Emulsion E₁ The resulted monodisperse type silver bromide emulsion was added with sodium carbonate and the pH was adjusted to be 7.5. Then, the resulted matter was added with thiourea dioxide in an amount of 12 mg per mol of silver halide and was then fogged by ripening at 65°C until the maximum characteristics was displayed. After then, the ripened emulsion was cooled down to 40°C and added with chloroauric acid in an amount of 6 mg per mol of silver halide, so that Emulsion E-1 was prepared. Preparation of Protective Layer Coating Solution Protective layer coating solution P-3 was prepared in the following manner. Pure water of 10 liters were added into 1 kg of gelatin. After the gelatin was swollen, the mixture was dissolved with heating. The resulted solution was added with 66 g of the following compound Q-2 as a dye, 500 ml of an aqueous solution of the following compound Q-1 as a coating aid, 10 g of amorphous silica gel having an average particle size of 8 µm as a matting agent, gelatin upon dispersion thereof, and 10 g of the following compound Q-3 as a dye, so that the protective layer coating solution P-3 was prepared. Preparation of Emulsion Coating Solution E₂ Emulsion coating solution E₂ was prepared in the following manner. Emulsion E₁ was added with the following compound Q-4 in an amount of 560 mg per mol of silver halide and the following compound Q-5 in an amount of 250 mg per mol of silver halide. The resulted mixture was then added with saponin in an amount of 3.9 g, and the aforegoing compound C-4, a latex polymer in an amount of 280 mg and dextrin in an amount of 5.6 g, each per mol of silver halide. After then, while adjusting the viscosity of the resulted matter at 35°C with a thickness agent so to be 15 CP, the emulsion coating solution E₂ was prepared. Preparation of Backing Layer Coating Solution B-2 The coating solution B-2 was prepared in the same manner as in the backing layer coating solution B-1, except that phenidone was added in an amount of 5 mg per gram of gelatin in place of Compound C-6 and pH was adjusted to be 5.4 with citric acid. Preparation of Protective Layer Coating Solution P-4 for Backing Layer The protective layer coating solution P-4 was prepared in the same manner as in the foregoing protective layer coating solution P-2, except that mucochloric acid was not added. Preparation of Samples for Evaluation The above-mentioned coating solutions were combined as shown in Table-5. The combination thereof was coated on one side after another of the both sides of a 100µm-thick polyethylene terephthalate film support provided thereon with an under-coat layer described in Example-1 of Japanese Patent O.P.I. Publication No. 59-09941 (1984), so that the samples for evaluation shown in Table-5 were prepared. In the preparation thereof, on one side of the support provided with the under-coat layer was coated with a backing under-coat layer by making use of the coating solution B-2 so that the dry-weight of gelatin could be 2 g/m² and, further, on the backing under-coat layer was coated with a backing protective layer by making use of the protective layer coating solution P-4 so that the dry-weight of gelatin could be 1 g/m², and each of them were then simultaneously dried. Next, the samples for evaluation, N-1 through N-13, were prepared in the following manner. On the other side of the support was coated with an emulsion layer by making use of the emulsion coating solution E₁ so that the dry-weight of gelatin could be 1.5 g/m² and the amount of silver coated could be 4.3 g/m². At the same time when the emulsion layer was coated on, an emulsion protective layer was further coated on the emulsion layer by making use of protective layer coating solution P-3 so that the dry-weight of gelatin could be 1 g/m²; with adding formalin as a hardener, and both of them were then dried. The drying conditions for the preparation are shown in Table-5. Coating and Drying Conditions A 35°C-coating solution was coated on and then treated for 7 seconds- by blowing the 5°C-air so that the solution was cooled down and set. Then, the resulted coated layer was dried with keeping the temperature of the coated layer surface at 10°C by blowing the dry air having a dry-bulb temperature of 23°C and a relative humidity of 20%, so as to make gelatin have a moisture content of 1600%. Next, the coated layer was dried by blowing the dry air having a dry-bulb temperature of 27°C and a relative humidity of 20%, so as to make gelatin have a moisture content of 1000%, while keeping the coated surface temperature at 13.8°C. The resulted sample was sectionalized into 14 portions and dried under the drying conditions shown in Table-4, so that Samples S-11 through S-24 were prepared. In addition, the same drying conditions were applied to both of the emulsion side and the backing layer side. Sample N-1 was further multi-sectionalized and one portion thereof was taken. Four minutes after the point of time when an average coated surface temperature of the portion became 1°C lower than the average drying air temperature, this portion was dried at a dry-bulb temperature of 40°C and relative humidity of 50% by taking 30 seconds. The resulted sample was named N-14. Similarly to the above, another portion thereof was taken and five minutes after the point of time when an average coated surface temperature of the portion became 1°C lower than the average drying air temperature, this portion was dried at a dry-bulb temperature of 40°C and relative humidity of 50% by taking 30 seconds. The resulted sample was named N-15. Samples N-1 through N-15 were cut into a size and packed under the conditions at 23°C and 35%RH. On the other hand, Samples R-1 through R-15 were prepared by coating, drying, cutting and packing, respectively, in quite the same manner as in the above-mentioned samples, except that the emulsion coating solution E₂ was used. Further, Samples T-1 through T-15 were prepared in such a manner that the samples, which had been treated under the same emulsion preparing conditions and in the same coating and drying processes each as in the samples N-1 throught N-15, were handled under the conditions at 23°c and 80%RH i.e., at a dew-point of 19°C, from the point of time when the coating and drying process was completed to the packing process. With respect to these groups of samples, the dimensional stability tests were tried and the surface cracks of their undeveloped samples were inspected, in the same manners as in Example-1. The cracks were inspected by observing the surface conditions by the eye. The cracks were graded by 5 levels, i.e., levels 5 and 4 have no problem, level 3 is acceptable on the market and levels 2 and 1 are impossible to commercialize. The results are shown in Table-6. As is obvious from the results shown in Table-6, the following facts were verified: Before an average surface temperature becomes 1°C lower than an average drying temperature, the drying conditions cannot given any special effect to both of dimensional stability and fixability, but can give good effects, provided only that the conditions can satisfy the conditions of the invention after the average surface temperature reached 1°C lower than the average drying air temperature; When a drying is carried out by blowing the drying air having a temperature of from 35°C to 80°C or a relative humidity of from 5% to 25% for a period of from 5 seconds to one minute after an average coated surface temperature become 1°C lower than an average drying air temperature, a desirable effect can be obtained. However, if the blowing time is shorter than the above, the dimensional stability effects may be diminished and, on the other hand, if it is blown for 2 minutes, a fixing fault may be produced; Those containing polymer latex are excellent in dimensional stabilities between pre- and post-processing as well as in physical properties; The advantages of the coating and drying conditions of the invention can more preferably be displayed by carrying out a series of the manufacturing processes from the point of time when a drying step is completed to a point of time when a packing step is completed, under the conditions of a dew-point of not higher than 16°C; and, The dry air may be specified by either relative humidity or temperature. However, a relative humidity required for the conditions of the invention may be obtained by either raising a drying air temperature or lowering a wet-bulb temperature of the drying air. Example-4 Negative type silver halide light-sensitive materials were prepared so as to serve as roomlight contact type light-sensitive material, in the following manner. Preparation of Emulsions In the following manner, silver chlorobromide emulsions each having a silver bromide content of 2 mol% were prepared. Silver chlorobromide emulsions having average grain sizes of 0.10µm, 0.20µm, 0.30µm and 0.40µm were prepared respectively in the same manner as Example 1. Preparation of Emulsion Coating Solutions Emulsion coating solutions E-1 through E-5 each shown in Table-1 were prepared in the following manner. After each of the aforementioned emulsion solutions was added with 9 mg of the following Compound K as a pasteurizer, the pH of the resulted solution was adjusted to be 6.5 with a 0.5 normal sodium hydroxide solution and was then added with tetrazolium compound T as a contrast hardening agent in an amount of 0.4x10⁻³ mol or 4x10⁻³ mol per mol of silver and, further, with 5 ml of a 20% aqueous saponin solution, 180 mg of sodium dodecylbenzenesulfinate, 80 mg of 5-methylbenzteriazole, 43 ml of the above-mentioned latex solution L for adding emulsion solution, 60 mg of the following Compound M and 280 mg of an aqueous polymer of a styrene-maleic acid copolymer in order. The resulted matter was added with water to make 475 ml. On the other hand, the emulsion coating solutions E-6 through E-10 each shown in Table-7 were prepared by adding hydrazine compound H as a contrast hardening agent in an amount of 0.4x10⁻⁴ mol or 4x10⁻⁴ mol per mol of silver in place of the terazolium compound T. Also, emulsion coating solutions E-11 through E-15 each shown in Table-1 were prepared by adding polyalkylene oxide compound P in an amount of 0.1x10⁻⁴ mol or 1x10⁻⁴ mol per mol of silver in place of the tetrazolium compound T. Further, an emulsion coating solution E-16 shown in Table-1 was prepared without adding any contrast hardening agent. Next, an emulsion protective layer coating solution was prepared in the following manner. Preparation of Emulsion-Protective Layer Coating Solution P-1 The solution P-1, was prepared in the same manner as P-1 in Example 1. Next, a backing layer coating solution applied to coat a backing under-coat layer was prepared in the following manner. Preparation of Backing Layer Coating Solution B-1 The solution B-1 was prepared in the same manner as solution B-1 in Example 1. Next, Protective layer coating solution P-2 for coating a protective layer of a backing layer was prepared in the following manner. Preparation of Protective Layer Coating Solution P-2 The coating solution P-2 was prepared in the same manner as solution P-2 in Example 1. Preparation of Samples for Evaluation use Each of the foregoing coating solutions was coated, in combination shown in Table-7, on one side after another of both sides of a 100µm-thick polyethylene terephthalate film support provided thereto with such an under-coat layer as described in Example-1 of Japanese Patent O.P.I. Publication No. 59-09941 (1984), so that each of the samples for evaluation use was prepared. In this preparation process, on one side of the support was coated with the backing layer coating solution B-1 so that the dry-weight of gelatin could be 2 g/m² and, on the B-1-coated layer was further coated with a backing protective layer by making use of the protective layer coating solution P-2 so that the dry-weight of gelatin thereof could be 1 g/m², and dried. Next, on the other side of the support was coated with an emulsion layer so that the dry-weight of gelatin could be 1.8 g/m² and the amount of silver coated could be 4.3 g/m² and, on the resulted emulsion layer was further coated with an emulsion protective layer by making use of the protective layer coating solution P-1 so that the dry-weight of gelatin could be 0.8 g/m², with adding formalin as a hardening agent, and dried. The drying conditions thereof are shown in Table-8. According to the combinations of the emulsion coating solutions used and the drying conditions shown in Table-8, the samples are designated as, for example, E-3b which means the sample prepared by making use of the emulsion coating solution E-3 shown in Table-7 and by drying it under the drying conditions b shown in Table-8, and so forth. Drying and Coating Conditions A 35°C-coating solution was coated on and then treated for 7 seconds by blowing the 5°C-air so that the solution was cooled down and coagulated. Then, the resulted coated layer was dried with keeping the temperature of the coated layer surface at 10°C by blowing the dry air having a dry-bulb temperature of 23°C and a relative humidity of 20%, so as to make gelatin have a moisture content of 1600%. Next, the resulted coated layer was dried with keeping the temperature of the coated layer surface at 13.8°C by blowing the dry air having a dry-bulb temperature of 27°C and a relative humidity of 20%, so as to make gelatin have a moisture content of 1000%. The resulted sample was sectionalized into 15 portions and dried under the drying conditions shown in Table-8, so that samples were prepared. In addition, the same drying conditions were applied to both of the emulsion side and the backing layer side. The sample dried under Condition a was further sectionalized into 3 portions and one portion thereof was taken. Four minutes after the point of time when an average coated surface temperature of the portion became 1°C lower than the average drying air temperature, this portion was dried at a dry-bulb temperature of 40°C and relative humidity of 22% by taking 30 seconds. The above-given drying conditions are designated as n. Similarly to the above, another portion thereof was taken and five minutes after the point of time when an average coated surface temperature of the portion became 1°C lower than the average drying air temperature, this portion was dried at a dry-bulb temperature of 40°C and relative humidity of 22% by taking 30 seconds. The drying conditions are designated as P. The drying condistions n are for the invention and those P are for the comparative purpose. The samples thus prepared were rehumidified for 12 hours under the conditions at an environmental temperature of 23°C and an environmental relative humidity of 40% and were then subjected to the following dimensional stability tests, the tests for fixing clearness time required and the sensitometric tests, respectively. The following three types of developers were selectively used according to the combination thereof with contrast hardening agents added thereto. Namely, Developer A was used to develop the samples added with a tetrazolium compound, Developer B to those with a hydrazine compound and Developer C to those with a polyalkylene oxide compound, respectively. It has been well-known that these combinations are desirable, according to the descriptions of, for example, Japanese Patent O.P.I. Publication No. 62-210458 (1987) and so forth and those combined developers are now available as the systems on the market from various manufacturers. Further, the following fixers and the automatic processors such as that shown in Fig. 1 were used. With this type of automatic processors, the line-speeds can be variable and the total processing time can also be controllable. In this example, the two types of rapid processes were carried out, i.e., one was carried out under the processing conditions shown in Tables 9-1 to 9-3 which are the standard conditions for the combinations, provided that the fixing temperature and time were as same as those for developing process, and the other was carried out by taking a total processing time of 50 seconds including 15 seconds for developing and 15 seconds for fixing. The results obtained from each processing are shown in Tables 9-1 through 9-3, respectively. Dimensional Stability Test Thus rehumidified samples were scarred at intervals of 560mm at an environmental temperature of 23°C and relative humidity of 40%. The scarred samples were processed with an automatic processor under the following processing conditions by making use of the following developer and fixer. Thus processed samples were rehumidified for 12 hours under the conditions of an environmental temperature of 23°C and relative humidity of 40% and the actual lengths of the scars left on the samples were then measured. Each value obtained by deducting the actual length of each scar from the aforegoing 560mm was regarded as a value of dimensional stability in terms of µm unit. A positive value thereof means that a sample was lengthened by the automatic processing. The more a sample is lengthened, the more a dimensional stability is lowered. Test for Fixing Clearness Time Required This tests was made by measuring a period of time from when dipping each sample in one liter of the above-mentioned fixer having a temperature of 34°C until when the sample became transparent. The test results were expressed in terms of seconds. The less the seconds are, the more the fixing property is excellent. Sensitometric Test Each of the above-mentioned samples was exposed to light through a glass-made wedge by making use of a roomlight type printer P-627FM manufactured by Dainippon Screen Mfg. Co. to which an electrodeless discharge tube manufactured by Fusion Co. of the U.S.A. was mounted. Composition of Developers Developer A : the same as mentioned in Example 1. Developer B Developer C A rapid lith developer, CDL-271 AB manufactured by Konica Corporation, was used. Composition of Fixer Composition A : The same as mentioned in Example 1. Rapid Processing Conditions Heat transmittance coefficient of a dryer: 180 Kcal/h.m².°C Environmental temperature and relative humidity of an automatic processor installed: 23°C and 40%RH The processing time of each processing step includes the time required for transporting film through the so-called cross-over sections between the respective processing steps. Time required for dry-to-dry: 50 seconds Line speed: 3000mm per minute As is obvious from Tables 9-1 through 9-3, only the samples satisfying the embodiments of the invention can give an excellent dimensional stability and, firther, only those having a grain size of from 0.1 to 0.3µm and gamma of not lower than 6 can give excellent dimensional stability and high gamma values in both of standard process and rapid process. Example-5 Each of the emulsion coating solutions E-1, E-3, E-6, E-8, E-11, E-13 and E-16 of Example-1 was added with 20 mg each of Compound DS as an organic desensitizing dye, respectively. The resulted samples were named X-1, X-3, X-6, X-8, X-11, X-13 and X-16. Those samples in which Compounds DS each was replaced by 200 mg of Compound U were named Y-1, Y-3, Y-6, Y-8, Y-11, Y-13 and Y-16, respectively. Under the conditions c which are for the embodiment of the invention among the coating and drying conditions for emulsions shown in Table-8 given in Example-4, the samples each were coated and dried, so that samples X1-C through X16-C and Y1-C through Y16-C were obtained. To the resulted samples, the same emulsion protective layers, backing layers and backing protective layers as those of Example-4 were used. With respect to the resulted samples, the dimensional stabilities, the time required for fixing clearness and sensitometries were measured in the same manners as in Example-1, respectively. In the step of exposing them to light, the wedgewise exposures were applied thereto similarly to the case of Example-1. The combination of the contrast hardening agent and developer each containing in the samples, the fixer composition and developing conditions were the same as in Example-4. The results thereof are shown in Table-10 According to the invention, as is obvious from Examples 1 through 3, it is possible to provide a silver halide photographic light-sensitive material excellent in dimensional stability, the manufacturing process thereof and the image-forming method suitable therefor. Further, it is possible to provide a silver halide photographic light-sensitive material excellent in dimensional stability and photographic characteristics and the manufacturing process thereof even in either the standard processing or a rapid processing when making a gamma value satisfactory as in Examples 4 and 5.
