Silver halide photographic product

Abstract: Disclosed is a color photographic product having a patrone or cassette cartridge and a silver halide color photographic material rolled in said patrone, which said halide color photographic material comprises; a support having a thickness of 90 µm or less, a backing layer on a first face of said support, a silver halide emulsion layer and a protective layer on a second face of said support, wherein each outermost layer on said first and second face has a coefficient of kinetic friction of 0.33 or less with respect to a velvet attached to an opening of said patrone and said opening has a gap of 0.5 to 2.9 mm. A silver halide photographic light-sensitive material according to this invention has improved flaw resistance, image sharpness and film abrasion resistance.

Description: FIELD OF THE INVENTION This invention relates to a silver halide photographic light sensitive material suitable for a compact-sized camera convenient for photographing and handling and, particularly, to a silver halide photographic light sensitive material capable of being made into a thin-layer and improved in flaw resistance, image sharpness and film abrasion resistance. BACKGROUND OF THE INVENTION For taking pictures on a trip for example, a small, pocket-sized camera has been put into practical use, because the camera can be ready to take pictures and convenient for handling and portability. On the other hand, cameras using a 35mm rollfilm are large in volume, heavy in weight and inconvenient for portability. Therefore, small-sized cameras such as a 110-size camera and a disk camera have been developed as portable cameras. With these cameras, however, the resulting image quality is deteriorated because the exposed image areas are also small-sized as the cameras are getting small-sized. The image quality deterioration is against the users' requirements for high image quality and is not acceptable by users. For satisfying the excellent portability requirement and the high image quality each required by users, it has been desired to produce a camera which is smaller in size without sacrificing the exposed image area. Therefore, it has been an essential theme to make a 35mm-size film cartridge smaller in size. The proportion of the volume which a light sensitive material occupies in a film cartridge is high. Therefore, reducing the volume of the light sensitive material could assist in making the film cartridge smaller. In the meanwhile, the volume of the light sensitive material depends upon the layer thickness of the light sensitive material, because most of the layer thickness of the light sensitive material is made up of a support. Therefore, attempts have been made to reduce the volume of a light sensitive material by making the support thinner so as to make the cartridge smaller in size. However, a new problem has arisen in that many scratches are produced on a film in the course of taking pictures and carrying out development. There is also another problem that film abrasion resistance is seriously deteriorated when winding up the film inside a camera. Further, the users' requirements for providing a high image quality cannot be satisfied, because the image sharpness is also deteriorated in practical photographing operation. SUMMARY OF THE INVENTION This invention was achieved to solve the above-described problems. It is, therefore, an object of the invention to provide a photographic light sensitive material convenient for handling, excellent in flaw resistance and image sharpness and less in film abrasion when winding up a film. The above-mentioned object of the invention can be achieved with a silver halide photographic light sensitive material comprising a support provided thereon with at least one silver halide emulsion layer, a backing layer and a protective layer; wherein the support thickness is not thicker than 90µm, the kinetic friction coefficient is not more than 0.33 to the velvet of the outermost layer of the backing layers and the kinetic friction coefficient is not more than 0.33 to the velvet of the outermost layer on the side provided with the silver halide emulsion layers. In the above-mentioned case, an organopolysiloxane is provided in the outermost layer of the protective layers on the emulsion layer side and also a compound having Formula (1) or (2) given below or chosen from any of compounds B-15 to B-31, B-55 to B-74 and B-93 to B-97, is provided in the backing layer. Formula (1) RCOOM wherein R represents an aliphatic hydrocarbon group and M represents an cation. wherein R 1 and R 2 represent each an aliphatic hydrocarbon group and X represents a divalent linkage group. It is preferred to provide organopolysiloxane in the outermost layer of the protective layers on the emulsion layer side and to provide a compound represented by Formula (1) or (2) given above in the outermost layer of the backing layers. DETAILED DESCRIPTION OF THE INVENTION The invention will now be detailed below. In the silver halide photographic light sensitive material of the invention, the support applicable thereto may have a thickness of not thicker than 90µm and within the range of, desirably, 50 to 90µm and, preferably, 60 to 80 µm. The kinetic friction coefficient of the silver halide photographic light sensitive material of the invention may be not more than 0.33 and within the range of, desirably not less than 0.10 to not more than 0.30 and, preferably not less than 0.12 to not more than 0.25 to the velvet of the outermost backing layers from the support and the velvet of the outermost silver halide emulsion layer from the support. The term, 'a kinetic friction coefficient to a velvet' herein means a kinetic friction coefficient when sliding the surface on the side of the emulsion layer of a sample on the surface of the backing layer of the sample with applying a load of 100g to a needle attached with a 1cm-square Nylon-made velvet to the point of the needle; provided, the test is to be tried under the conditions of 23°C and 55%RH.

In the invention, the preferable compounds among them include those having the structural unit represented by the following formula (3). wherein R 1 represents a hydrogen atom, a hydroxyl group or an organic group and R 2 represents an organic group. The organic groups represented by R 1 and R 2 preferably include, for example, the following groups; namely, an alkyl group (preferably including those having each 1 to 18 carbon atoms), a substituted alkyl group (e.g., a carboxyalkyl group, an aminoalkyl group, an alkylaminoalkyl group, a mercaptoalkyl group, an alkoxyalkyl group, a glycidyloxyalkyl group, an aralkyl group, an aryloxyalkyl group, and -R 3 -R 4 -R 5 - group (in which R 3 represents an alkylene group, R 4 represents a group linked to not less than two oxyalkylene groups and R 5 represents an alkyl group), an alkenyl group (e.g., a vinyl group and an allyl group), an alkoxy group (e.g., a methoxy group and an ethoxy group), an aromatic group (e.g., a phenyl group) and a group containing the above groups. The terminals of the organopolysiloxane preferably have a structural unit having the following formula (4). wherein R 6 , R 7 and R 8 represent each a hydrogen atom, a hydroxyl group or an organic group and the organic groups include, for example, those given for R 1 and R 2 . There is no special limitation to the viscosity of the organopolysiloxane applicable to the invention. However, the viscosity thereof measured at 25°C is suitably within the range of from 20 to 100000 centistokes. The polysiloxane suitably has a molecular weight within the range of from 1000 to 1000000. When it is within the above-mentioned range, it may be used to meet the purposes. However, it is preferably within the range of from 2000 to 50000. Next, typical compounds applicable to the invention will be given below. Exemplified compounds A In the invention, it is preferred to provide organopolysiloxane in a non-light-sensitive outermost layer. When adding organopolysiloxane, it is preferred to provide it in a proportion within the range of from 0.3 to 30% by weight of a water-soluble binder for forming the layer, such as gelatin. The protective layers relating to the invention are allowed to contain well-known materials for protective layers of an ordinary silver halide photographic light sensitive material, besides the organopolysiloxane. The thickness of the protective layer containing organopolysiloxane is suitably within the range of from 0.1 to 5.0µm and, preferably, from 0.3 to 1.5µm. As for the dispersants of organopolysiloxane, it is allowed to use any surfactants commonly applicable to photographic use. They include, for example, those selected suitably from the group consisting of an anionic surfactant, a nonionic surfactant, an amphoteric surfactant and a cationic surfactant. When making use of the above-mentioned surfactant and a supersonic or valve homogenizer, a dispersion can be performed. The preferred particle sizes of the dispersants are within the range of from 0.05 to 10µm. When the particle size thereof is too small, the slidability is deteriorated and, when it is too large, the subject light sensitive material is less suitable, because a devitrification is produced. Upon further investigation, the present inventors discovered, in the case where a protective layer containing organopolysiloxane is provided over a silver halide emulsion layer, that a roller-staining production can remarkably be improved by providing a high-boiling organic solvent either in the protective layer or in a substantially non-light-sensitive interlayer interposed between the protective layer and the silver halide emulsion layer. The thickness of the above-mentioned interlayer is suitably within the range of from 0.1 to 5.0µm and, preferably from 0.3 to 2.0µm. The interlayer may also contain a UV absorbent and a formalin scavenger, besides the above-mentioned high-boiling organic solvent. The high-boiling organic solvents applicable thereto may be a liquid and an organic compound having a boiling point of not lower than 150°C. Among the high-boiling organic solvents, preferred examples include a phthalic acid ester, a phosphoric acid ester, an acid amide, a glycol derivative, an aliphatic dicarboxylic acid derivative and a phenol derivative, such as those given in JP OPI Publication No. 62-249145/1987, pp.10-11. The high-boiling organic solvents may be provided in a proportion within the range of from 1 to 150% by weight to 100% by weight of a hydrophilic colloidal binder such as gelatin, desirably within the range of from 3 to 30% by weight and, preferably within the range of from 3 to 30% by weight. The particles sizes thereof are preferably within the range of from 0.005 to 0.5µm. In the invention, it is preferred that the outermost layer of the backing layers may contain a higher aliphatic acid represented by the foregoing formula (1) or (2) (or the salts thereof), or an aliphatic hydrocarbon group-containing ester having at least 8 carbon atoms, that is, an aliphatic ester having at least the total 24 carbon atom numbers of the aliphatic hydrocarbon group thereof. Formula (1) RCOOM wherein R represents an aliphatic hydrocarbon group, preferably having from 12 to 70 carbon atoms and the group may have a substituent; and M represents a cation including, for example, a hydrogen atom, a metal such as Na, K, Li, Mg, Ca, Sn and Ba, HN(R 2 ) 3 or N(R 2 ) 4 (in which R 2 represents an alkyl group having 1 to 18 carbon atoms or a substituted alkyl group). In the invention, the cation represented by M is preferably one of the metals above. wherein R 1 and R 2 represent each, desirably, an aliphatic hydrocarbon group having from 12 to 70 carbon atoms and a total number of carbon atoms of R 1 and R 2 within the range of from 24 to 140, and X represents a divalent linkage group. More desirably, at least one of R 1 and R 2 is a branched aliphatic hydrocarbon group having 12 carbon atoms and they have a total number of carbon atoms of R 1 and R 2 within the range of from 32 to 140.

The above-given compounds may be used independently or in combination. The binders jointly applicable thereto include, for example, a polymer or copolymer of polystyrene, polymethyl methacrylate, polyvinylidene chloride, polyacrylonitrile or polyvinyl acetate; a cellulose derivative of cellulose diacetate, cellulose triacetate, cellulose nitrate, ethyl cellulose or cellulose propionate; and an acetal such as polyvinyl formal, polyvinyl acetal and polyvinyl benzal. There is no limitation thereto, provided, they shall have a layer-forming function and can also be dissolved in a solvent. The compounds represented by Formula (1) or (2) are used in an amount within the range of, desirably, from 1 to 500mg and, preferably, from 5 to 100mg per sq.meter of a light sensitive material used. The hydrophilic colloids applicable to the invention include, besides gelatin, for example, a derivative of gelatin, colloidal albumin, agar, gum arabic, alginic acid, cellulose derivatives such as a cellulose acetate so hydrolyzed as to contain acetyl in a proportion up to 19 to 26%, acrylamide, imidopolyacryl amide, casein, a vinyl alcohol polymer containing a urethane carboxylic acid group or a cyanoacetyl group, such as vinyl alcohol and a vinyl cyanoacetate copolymer, polyvinyl alcohol, polyvinyl pyrrolidone, hydrolyzed polyvinyl acetate, and a polymer prepared by polymerizing a protein or an acylation-saturated protein with a monomer having a vinyl group. In the invention, it is desirable if required to use a variety of physical layer property improvers such as a layer hardener, for the purpose of improving the physical properties of a coated layer comprising the above-mentioned hydrophilic colloids. When making use of a layer hardener in combination, for example, not only are there synergistic effects on scratch-prevention, but also the mechanical strength of coated layers and the antisolving characteristics against processing solutions can also be improved, so that a light sensitive material having an excellent physical layer property can be prepared. When making use of gelatin as the hydrophilic colloid, typical examples of layer hardeners include, specifically, those of the aldehyde type, epoxy type, ethylene imine type, active halogen type, vinyl sulfone type, isocyanate type, sulfonic acid ester type, carbodiimide type, mucochloric acid type and acyloyl type. The gelatin layer hardeners applicable to the invention are given in, for example, U.S. Patent Nos. 3,539,644, 3,642,486, 2,726,162, 2,816,125 and 3,047,394; West German Patent No. 1,085,663; British Patent No. 1,033,518; JP-EP No. 48-3549/1973; PB Report No. 19921; U.S. Patent Nos. 2,950,197, 2,964,404, 2,983,611, 3,271,175, 2,938,892, 3,640.720, 3,058,827 and 1,994,611; British Patent Nos. 822,061, 1,042,083, 1,202,052 and 1,230,354; West German Patent No. 872,153; JP-EP Nos. 44-29622/1969, 47-25373/1972, 47-8736/1972 and 46-38715/1972; JP OPI Publication Nos. 49-73122/1974, 48-74832/1973, 49-24435/1974, 48-43319/1973, 48-43320/1973 and 49-116154/1974; and JP Application Nos. 48-112325/1973, 48-110996/1973 and 49-15096/1974. The layer hardeners may be used in any amount, provided that the kinds of the objective gelatin layers, the physical properties required and the photographic characteristics can be satisfied without spoiling any of the effects of the invention. However, the layer hardeners are contained in a proportion of not less than 0.01% by weight and desirably not less than 1% by weight of the amount of the gelatin in dried state contained in the outermost layer or other hydrophilic colloidal layers of a light sensitive material of the invention.

A layer containing an antistatic agent may be provided to the support side of the outermost backing layer. The antistatic agents for this purpose include, for example, the ionen type polymers given in JP-EP No. 57-56059/1982, the cross-linked polymers having a quaternary ammonium vinylbenzylate on the polymer position, the electrolyte-containing alumina sol given in JP-EP No. 57-12979/1982 and the fine particles of the crystalline metal oxides given in JP OPI Publication No. 56-143431/1981. When making use of the above-mentioned ion type polymer, there may be some instances where a scum may be produced in a light sensitive material, because the resistance of these types of polymers are relatively deteriorated against the compositions of an aqueous developing solution. When a layer containing a compound represented by Formula (1) or (2) is provided on the outermost backing layer, the above-mentioned defect can be improved, because the outermost layer displays an effect that any permeation of the ion type polymers into a developing solution can be prevented. When making use of the above-mentioned alumina sol having an electrolytes or the fine particles of crystalline metal oxide as an antistatic agent, the coatability of the outermost backing layer can be excellent and the adhesion property between the outermost layer and an antistatic agent-containing layer can also be improved, so that a light sensitive material can be prepared so as to have an excellent slidability and an improved dried-unevenness. When a compound represented by the foregoing Formula (1) or (2) is provided in the outermost backing layer, the outermost layer on the back surface or a layer containing an antistatic agent may contain, if required, a matting agent, a surfactant and a dye. As for the matting agents, fine particles of silicon dioxide having an average particle size within the range of from 0,01 to 10µ may preferably be used. There is no special limitation to the above-mentioned various additives, the various additives for light sensitive silver halide emulsion layers and the preparation procedures thereof. For details thereof, the descriptions in Research Disclosure, Vol.176, pp.22-31, Dec., 1978, for example, may be referred. The other layers than the above-mentioned layers, such as a binder layer, may also be arranged between the outermost backing layer and an antistatic agent-containing layer. The methods for coating the layer containing a compound represented by Formula (1) or (2) include well-known methods such as a curtain-coating method, a reverse-roll coating method, a fountain air doctor coating method, a slide-hopper coating method, an extrusion coating method and a dipcoating method. The photographic component layers relating to the invention may also contain a latex-like water-dispersible vinyl compound. As for the latexes, a homo- or co-polymer such as those of alkyl acrylate, alkyl methacrylate, acrylic acid, methacrylic acid, glycidyl acrylate, styrene, vinyl chloride and vinylidene chloride may be used. The silver halide emulsions applicable to the invention can be chemically sensitized by any ordinary methods. The chemical sensitization thereof can be performed with noble metal salts including, for example, a gold compound, platinum, palladium, rhodium and iridium, such as those given in U.S. Patent Nos. 2,399,083 and 2,597,856; the sulfur compounds given in U.S. Patent Nos. 2,410,689 and 3,501,313 and, besides, a stannous salt and an amine. The silver halide emulsions applicable to the invention may contain a stabilizer or an antifoggant including, for example, 4-hydroxy-6-methyl-1,3,3a,7-tetrazaindene, 3-methyl-benzothiazole, 1-phenyl-5-mercaptotetrazole and, besides, many kinds of heterocyclic compounds, mercury-containing compounds, mercapto compounds and metal salts. In the silver halide emulsions applicable to the invention, it is also allowed to use therein a variety of spectrally sensitizing dyes such as a melocyanine dye, a carbocyanine dye and a cyanine dye so as to meet the purposes of the emulsions. In the invention, is is further allowed to use a color coupler such as a 4-equivalent type methylene yellow coupler, a 2-equivalent type diketomethylene yellow coupler, a 4- or 2-equivalent type pyrazolone or indazolone magenta coupler and an α-naphthol type or phenol type cyan coupler. It is further allowed to use therein the so-called DIR couplers. In addition to the above, the photographic component layers of the light sensitive materials of the invention are allowed to contain a dye, a UV absorbent, such a layer hardener as mentioned above, a surfactant and a polymer latex. The supports applicable to the light sensitive materials of the invention include, for example, a sheet of film or baryta paper made of a polyolefin (such as polystyrene), a cellulose derivative (such as polystyrene and cellulose triacetate), a polyester (such as polyethylene terephthalate), a support comprising a sheet coated with the above-given polymer film on the both sides of a synthetic paper or paper and the analogous materials thereof. The photographic component layers of the light sensitive materials of the invention may be coated independently one after another or altogether simultaneously in various methods such as a dip coating method, an air-knife coating method, a curtain coating method and an extrusion coating method. For the details of various additives, vehicles, supports and coating methods, the descriptions in 'Product Licensing Index' Vol.92, pp.107-110, Dec., 1971 can be referred.

A silver iodobromide emulsion was prepared in a double-jet method, by making use of a monodisperse type silver iodobromide grains having an average grain size of 0.33µm (and having a silver iodide content of 2 mol%) as the seed crystals. Keeping the solution <G-1> at a temperature of 70°C, the pAg at 7.8 and the pH at 7.0 and stirring it well, a seed emulsion was added thereto in an amount equivalent to 0.34 mols. (Formation of internally high iodine phase, -core phase-) Then, keeping the flow rate of <H-1> to <S-1> at 1 : 1, the solutions were added by taking 86 minutes at an accelerated flow rate (the final flow rate was 3.6 times as much as the initial flow rate.) (Formation of externally low iodine phase, -shell phase-) Successively, keeping the pAg and pH at 10.1 and 6.0 and the flow rate of <H-2> to <S-2> at 1 : 1, the solutions were added by taking 65 minutes at an accelerated flow rate (the final flow rate was 5.2 times as much as the initial flow rate.) The pAg and pH in the course of forming grains were controlled with an aqueous potassium bromide solution and an aqueous 56% acetic acid solution. After the grain formation was completed, the grains were washed with water in an ordinary flocculation method. The grains were redispersed by adding gelatin. The pAg and pH thereof were then adjusted to 5.8 and 8.06 at 40°C. The resulting emulsion was a monodisperse type emulsion containing octahedral silver iodobromide grains having an average grain size of 0.80µm, a distribution range of 12.4% and a silver iodide content of 8.5 mol%.

The resulting emulsions were each core/shell type monodisperse type emulsions having a distribution range of not wider than 20%. Each emulsion was subjected to an optimum chemical ripening treatment in the presence of sodium thiosulfate, chloroauric acid and ammonium thiocyanate and a sensitizing dye, 4-hydroxy-6-methyl-1,3,3a,7-tetrazaindene and 1--henyl-5-mercaptotetrazole were then added. H-2 (CH 2 =CHSO 2 CH 2 ) 2 O The above-mentioned light sensitive materials further contained the following components; namely, compounds Su-1 and Su-2, a viscosity controller, layer hardeners H-1 and H-2, stabilizer ST-1, antifoggants AF-1 and AF-2 (having weight average molecular weights of 10,000 and 1,100,000), dyes AI-1 and AI-2 and compound DI-1 (in an amount of 9.4 mg/m 2 ), respectively. Components A : B : C = 50 : 46 : 4 (mol ratio) The resulting samples 1 to 35 were each cut to a size of 35mm x 117cm and it was checked whether each of these cut pieces could be stored in a cartridge having an inner diameter of 18mm. The results thereof are indicated by a mark ○ when it was stored in the cartridge and by × when it could not be stored therein. Also, the samples 1 to 35 were further prepared and were then each cut to a size of 35mm x 117cm. The resulting cut pieces were stored in the (current type of) cartridges having an inner diameter of 22mm and were each subjected to forced aging tests (at 55°C for one day) while keeping them in the state where they were so fixed as not to be rotated by a rotation stopper, respectively. After that, the rotation stopper was removed and a backing layer in a velvet portion was sprinkled with a suitable amount of sand. The samples were then stored in FT-1 produced by Konica Corp and the subject light sensitive materials were fully taken up, respectively. Next, the light sensitive materials were developed in the following processing steps and the resulting pressure-fog production thereon were evaluated. How to evaluate the pressure-fog production: The yellow density of the resulting line-formed fog and the density in the not-scratched portion were measured by a microdensitometer, so that the density difference ΔD was obtained and the evaluations were made in the following evaluation grades. ○ : ΔD = 0 to 0.06 Δ : ΔD = 0.06 to 0.12 × : ΔD = 0.13 to 0.19 ×× : ΔD = Not less than 0.20 The kinetic friction coefficients of the outermost backing layer and the outermost emulsion layer each of the samples to the velvets were measured by making use of a 1cm 2 sized Nylon-made velvet under the conditions of a 100g load applied and a frictional sliding speed of 10cm/min; (provided, the temperature and humidity were kept at 23°C and 55%RH, respectively.) A light-shielding member consisting of pile (material: nylon 66, young's modulus: 200kg/mm 2 , thickness: 100 D/48F, filament density: 36500 filaments/cm 2 ) and a rayon foundation was glued on a cartridge slit through which a film passes. For gluing, the method disclosed in Japanese Patent Application No. 75207/1985 was employed. The width of the cartridge slit through which a film passes was set to 2.2mm and the height of the light-shielding member was set to 1.5mm. The results thereof are shown in Table-2.

The color developing solution, bleaching solution, fixing solution, stabilizing solution and the replenishing solutions used therein were as follows.

With a sample comprising a support having a thickness of not thicker than 90µm, it was found that a sample could not be put to practical use when the outermost backing layer and the outermost layer on the emulsion layer side of the sample have each a kinetic friction coefficient greater than 0.33 to the velvets, because such a sample produces many pressure fogs. On the contrary, it was found that the above-mentioned pressure fog production could particularly be improved when the samples contain organopolysiloxane in the outermost protective layer on the emulsion layer side and also contain a higher aliphatic acid (or the salts thereof) or an aliphatic ester in the outermost backing layer. EXAMPLE 2 Samples 36 to 56 were each prepared in the same manner as in Example 1; except that the thicknesses of the supports, the kinetic friction coefficients of the sample surfaces to the velvets and the exemplified compounds A and B used therein were changed as shown in Table-2. The resulting samples were stored in the cartridges having an inner diameter shown in Table-2. The flaw resistance and perforation-breakage of the samples were evaluated in the following measuring methods and the pressure fogs produced after developments were also evaluated in the same manner as in Example 1. A light-shielding member consisting of pile (material: nylon 66, young's modulus: 200kg/mm 2 , thickness: 100 D/48F, filament density: 36500 filaments/cm 2 ) and a rayon foundation was glued on a cartridge slit through which a film passes. For gluing, the method disclosed in Japanese Patent Application No. 75207/1985 was employed. The width of the cartridge slit through which a film passes was set to 2.2mm and the height of the light-shielding member was set to 1.5mm. Measurement of flaw resistance A 35mm x 117cm sized film (for 24 exposures) was stored in a cartridge having an inner diameter shown in Table-2 and was then subjected to a forced aging test (at 55°C for one day long). After that, the backing layer side of the film was sprinkled over the velvet portion of a cartridge with a suitable amount of sand and the film was then pulled out at a rate of 20cm/second. The resulting flaws produced on the backing layer surface of the film were evaluated in the following evaluation grades. Evaluation grades of flaw resistance: ○ : No flaw found at all, Δ : Slight flaws found, and × : Serious flaws found. Measurement of perforation breakage A 35mm x 117cm sized film (for 24 exposures) was stored in a cartridge having an inner diameter shown in Table-2 and was then subjected to a forced aging test (at 55°C for one day long). After that, the film was then pulled out at a rate of 50cm/second. The resulting perforation breakage were evaluated in the following evaluation grades. Evaluation grades of perforation breakage: ○ : No breakage found at all, Δ : Breakage found in some portions, and × : Serious breakage found. As is obvious from Table-2, it was proved that the excellent evaluation of the flaw resistance, perforation breakage and pressure fog production could be obtained when adding the lubricants [namely, organopolysiloxane to the outermost protective layer on the emulsion layer side and a higher aliphatic acid (or the salts thereof) or an aliphatic ester to the outermost backing layer] to both sides of the sample of the invention. EXAMPLE 3 Samples 57 through 81 were each prepared in the same manner as in Example 1; provided, the thicknesses of the supports, the kinetic friction coefficients of the sample surfaces to the velvets and the exemplified compounds A and B used therein were changed as shown in Table-3. The flaw resistance, perforation breakage and pressure fog production of the resulting samples were evaluated in the same evaluation methods as in Example 2. A light-shielding member consisting of pile (material: nylon 66, young's modulus: 200kg/mm 2 , thickness: 100 D/48F, filament density: 36500 filaments/cm 2 ) and a rayon foundation was glued on a cartridge slit through which a film passes. For gluing, the method disclosed in Japanese Patent Application No. 75207/1985 was employed. The width of the cartridge slit through which a film passes was set to 2.2mm and the height of the light-shielding member was set to 1.5mm. The results thereof are shown in Table-3. As is obvious from Table-3, it was proved that the flaw resistance could be excellent, any perforation breakage could be eliminated and any pressure fog could not be produced, because the outermost layers on both sides of the samples of the invention have a kinetic friction coefficient of not greater than 0.33 to the velvet. On the other hand, it was also proved that, when the outermost layer on one side of a sample has a kinetic friction coefficient of not greater than 0.33, the flaw resistance could not fully be achieved and evaluation of both the perforation breakage and pressure fog production could not be satisfactory. EXAMPLE 4 Samples 82 to 102 were each prepared in the same manner as in Example 1; except that the thickness of the supports was changed to 90µm, and the kinetic friction coefficients of the sample surfaces and the kinds and amounts of exemplified compounds A and B used therein were also changed as shown in Table-4. The flaw resistance, perforation breakage and pressure fog production of the resulting samples were evaluated by the same evaluation methods as in Examples 1 and 2. The results are shown in Table-4. As is obvious from Table-4, it was proved that, when changing the amounts of exemplified compounds A and B used therein, the kinetic friction coefficients of the sample surfaces could be decreased and excellent effects on the flaw resistance and the prevention of perforation breakage and pressure fog production could also be demonstrated.
