Silver halide color photographic photosensitive material

A silver halide color photographic photo-sensitive material comprises a support, and a layer arrangement formed on the support. The layer arrangement includes a red-sensitive silver halide emulsion layer containing a color coupler capable of forming cyan dye upon reacting with an oxidation product of a developing agent, a green-sensitive silver halide emulsion layer containing a color coupler capable of forming magenta dye upon reacting with the oxidation product of the developing agent, and a blue-sensitive silver halide emulsion layer containing a color coupler capable of forming yellow dye upon reacting with the oxidation product of the developing agent. The red-sensitive layer has a sensitivity at 650 nm of 50% or less of its maximum sensitivity, and contains substantially no magenta-colored couplers.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to a silver halide color photographic 
photosensitive material and, more particularly, to a color photographic 
photosensitive material which can reproduce various hues and lightnesses 
of red and green, all faithful to those of the original images, and which 
can therefore form images with faithful shadings and rich in stereoscopic 
effect. 
2. Description of the Related Art 
As is known in the art, interlayer effect or interimage effect can be 
utilized in order to improve the color reproducibility of color 
photographic photosensitive material. In the case of a color negative 
photosensitive material, the color emission of a red-sensitive layer in 
white exposure can more be inhibited than that in red exposure by applying 
development-inhibiting effect from a green-sensitive layer to the 
red-sensitive layer. In the case of color negative paper, the interlayer 
effect achieves cyan-dye formation in a density higher in the case where 
the paper is red-exposed than in the case where the paper is gray-exposed. 
It is because the gradation is balanced such that gray will be reproduced 
on the color print when the paper is exposed to white light. As a result 
of this, red of higher saturation can be reproduced on the print, with the 
cyan dye formation greatly inhibited. For the same reason, green of high 
saturation can be reproduced on the print by applying 
development-inhibiting effect from the red-sensitive layer to the 
green-sensitive layer. 
Various methods are known which work to promote the interlayer effect. One 
of them is to make use of the iodine ions released from the silver halide 
emulsion during development. In the method, a layer containing much silver 
iodide is used as layer for providing interlayer effect, whereas a layer 
containing less silver iodide is used as a layer for receiving the 
interlayer effect. Another known method of promoting the interlayer effect 
is disclosed in JP-A-50-2537 ("JP-A" means Published Unexamined Japanese 
Patent Application). In this method, a coupler is added to the layer 
providing the interlayer effect, said coupler releasing a development 
inhibitor when it reacts, in a paraphenylenediamine-based color developing 
solution, with the oxidation product of the developing agent. Still 
another known method of promoting interlayer effect is the so-called 
"automatic masking method," in which a colored coupler is added to an 
uncolored coupler, thereby masking the unnecessary absorption of the dye 
in the uncolored coupler. More specifically, the colored coupler can be 
added in an amount more than required to mask the unnecessary dye 
absorption, thus accomplishing the same effect as the interlayer effect. 
SUMMARY OF THE INVENTION 
An object of the present invention is to provide a silver halide color 
photographic photosensitive material which can reproduce both green and 
red of various hues and lightnesses faithfully. 
According to the invention, there is provided a silver halide color 
photographic photo-sensitive material, comprising: a support; and a layer 
arrangement formed on said support and comprising: a red-sensitive silver 
halide emulsion layer containing a color coupler capable of forming cyan 
dye upon reacting with an oxidation product of a developing agent, a 
green-sensitive silver halide emulsion layer containing a color coupler 
capable of forming magenta dye upon reacting with the oxidation product of 
the developing agent, and a blue-sensitive silver halide emulsion layer 
containing a color coupler capable of forming yellow dye upon reacting 
with the oxidation product of the developing agent; said red-sensitive 
layer having a sensitivity at 650 nm of 50% or less of its maximum 
sensitivity, and containing substantially no magenta-colored couplers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
In order to increase chromatics of green, the inventor prepared a color 
negative film by applying a magenta-colored cyan coupler, which has been 
commonly applied to color negative film since 1960s, to a red-sensitive 
silver-halide emulsion layer, and also adding a DIR compound to the 
red-sensitive silver-halide emulsion layer, thus promoting the interlayer 
effect applied from the red-sensitive layer to the green-sensitive layer. 
The inventor took pictures of green objects, and printed the photographed 
images on a color paper. The inventor examined the printed images, finding 
that the images were poor in shading and, hence, lacking stereoscopic 
effect. Then, the inventor studied the reasons for the poor shading. It 
was found that the shading had greatly depended on the way of applying the 
interlayer effect. 
To be more specific, the present inventor found that a color reproduction 
rich in green shading and excellent in stereoscopic effect can be obtained 
if the red-sensitive and green-sensitive emulsion layers are so designed 
that the masking from the red-sensitive layer to the green-sensitive layer 
is insufficient, i.e., under-masking, when the green-sensitive layer does 
not sense the light and the red-sensitive layer senses the light, and that 
the degree of masking from the red-sensitive layer to the green-sensitive 
layer becomes larger, from normal-masking to finally over-masking, as the 
green-sensitive layer senses more and more light. 
Conversely, when a colored coupler was added to the red-sensitive layer in 
an excessive amount, without adding a substance, such as a DIR coupler, 
which promotes the interlayer effect by development inhibition, thereto 
and the red-sensitive layer masks the green-sensitive layer to an excess, 
magenta dye can hardly enter the shadow portions of green on the print, 
inevitably lessening the shading effect. In this case, the red-sensitive 
emulsion layer performs an over-masking on the green-sensitive emulsion 
layer, regardless of the light-sensing level of the green-sensitive layer. 
Further, the inventor hereof repeated experiments in order to find the best 
possible method of applying the interlayer effect to the red-sensitive 
emulsion layer so that red shading is reproduced faithfully to those of an 
object with the increase in lightness of red. Finally, the inventor found 
that, unlike in the fidelity of reproduced green shading, the fidelity of 
reproduced red shading greatly depends on the spectral sensitivity 
distribution of the red-sensitive silver-halide emulsion layer. In other 
words, the reproduced red shading can be sufficiently faithful to those of 
the object, provided that the wavelength which provides the maximum 
sensitivity of the red-sensitive emulsion layer falls within a range of 
595 to 645 nm, which is the range for the ordinary photographic color 
photosensitive material, and that the sensitivity thereof at 650 nm is 50% 
or less of the maximum sensitivity. 
As a result of the experiments the present inventor has finally found that 
a silver halide photographic color photosensitive material which can 
reproduce green and red, which are important as colors of objects of 
photography, with high stereoscopic effect can be established. More 
specifically, the present invention is directed to a photosensitive 
material comprising a support, and a layer arrangement formed on the 
support and including a red-sensitive silver halide emulsion layer 
containing a color coupler which forms cyan dye upon reaction with the 
oxidation product of a developing agent, green-sensitive silver halide 
emulsion layer containing a color coupler which forms magenta dye upon 
reaction with the oxidation product of the developing agent, and a 
blue-sensitive silver halide emulsion layer containing a color coupler 
which forms yellow dye upon reaction with the oxidation product of the 
developing agent, the red-sensitive emulsion layer has a sensitivity at 
650 nm of 50% or less of its maximum sensitivity, and the red-sensitive 
emulsion layer contains substantially no magenta colored coupler. 
The spectral sensitivity distribution of the silver halide color 
photographic photosensitive material must be obtained in order to 
determine a wavelength of light rays to which the red-sensitive layer 
exhibits its maximum sensitivity, and also a sensitivity at a specified 
wavelength. The spectral sensitivity distribution can be obtained by means 
of an equi-energy spectral sensitometer. 
The maximum sensitivity wavelength of the red-sensitive emulsion used in 
the present invention falls within a range of 595 to 645 nm. Otherwise, 
the silver halide color photographic photosensitive material cannot 
reproduce color hues as defined by the standard color chip such as the 
color chart published by Macbeth Co., Ltd. 
Preferably, the sensitivity at 650 nm of the red-sensitive emulsion is 30% 
or less of its maximum sensitivity. 
The words "substantially no magenta-colored coupler" means that the 
red-sensitive layer provides under-masking to the green-sensitive layer, 
when it is exposed singly. In other words, it means that when only the 
red-sensitive layer is exposed and developed, and the density is measured 
using a green filter, a negative image is observed. The gradient of the 
negative image, i.e., the ratio of the density to the logarithm of light 
exposure applied to the red-sensitive layer is 0.05 or more. 
It is desirable that the red-sensitive layer contains 10 mol % or less, 
preferably 5 mol % or less, of magenta-colored coupler per mol of the 
un-colored cyan dye forming coupler. Nonetheless, the content of the 
magenta-colored coupler can be more than 10 mol % if the red-sensitive 
layer which mainly develops cyan contains, for some reason, a 
magenta-developing coupler such as an uncolored magenta coupler, an 
yellow-colored magenta coupler, or a magenta DIR coupler. Whether the 
content of the magenta-colored coupler exceeds 10 mol % or not, it would 
suffice if the resultant negative image has the gradient of 0.05 or more, 
as described above. 
The green-sensitive emulsion layer used in the present invention can have 
either a single-layer structure of a multi-layer structure. To intensify 
the effect of the invention, the green-sensitive layer should better be 
development-inhibited by any other layer of the color photographic 
photosensitive material. In order to intensify the interlayer effect from 
the red-sensitive layer, in proportion to the photosensing level of the 
green-sensitive layer, it is advisable to increase the silver/coupler 
ratio of the high-speed green sensitive sub-layer which develops color 
mainly when the photosensing level is low, thereby suppressing the 
developed color-density reduction resulting from the 
development-inhibiting substance used, and to decrease the silver/coupler 
ratio of the lower-speed green-sensitive sub-layer, thereby promoting the 
developed color-density reduction. Also, to intensify the interlayer 
effect the red-sensitive layer imparts to the green-sensitive layer, it is 
advisable that a coupler whose graininess may easily be lost be used in 
combination with silver halide in the high-speed sub-layer, or, for 
example, the high-speed sub-layer be formed of a monodispersed silver 
halide emulsion. Equally advisable is that the high-speed layer contain a 
two-equivalent coupler which is likely to lose its graininess. 
For similar reasons, it is recommendable to add a low-speed coupler and a 
high-speed coupler to the high-speed and low-speed green-sensitive 
sub-layers, respectively. 
Moreover, the silver halide emulsion color photographic photosensitive 
material according to the invention can attain better color photographic 
properties by modifying the layer which imparts the interlayer effect. For 
instance, to enhance the interlayer effect of the red-sensitive layer in 
proportion to the photosensing level of the green-sensitive layer, at 
least one sublayer of the red-sensitive layer or a layer adjacent thereto 
contains a compound which cleaves upon reacting with the oxidation product 
of a color developing agent to form a cleaved product, which in turn 
cleaves the development inhibitor upon reacting with another molecule of 
the oxidation product of the color developing agent. The interlayer effect 
of the red-sensitive layer can be enhanced by this method, probably for the 
following reason. 
After the first-stage reaction of the commonly used DIR compound, that is, 
after the reaction with the oxidation product of the color developing 
agent, which has been generated in the red-sensitive emulsion layer, the 
DIR compound cleaves the development inhibitor or the compound which 
releases the development inhibitor upon lapse of a predetermined time. By 
contrast, the compound used in the invention does not release the 
development inhibitor or the compound which releases the inhibitor upon 
lapse of the predetermined time, unless the compound cleaved in the 
first-stage reaction further reacts with another molecule of the oxidation 
product of the color development agent. Hence, the compound cleaved in the 
first-stage reaction diffuses into the green-sensitive silver-halide 
emulsion layer. The higher the concentration of the oxidation product of 
the color developing agent, the more development inhibitor the diffused 
compound will release, or the more compound, which releases the inhibitor 
upon lapse of the predetermined time, the diffused compound will release, 
thus inhibiting the development. In other words, the higher the 
photosensing level of the green-sensitive layer, the more prominent is the 
interlayer effect which the red-sensitive layer imparts to the 
green-sensitive layer, and the excessive is the masking which the 
red-sensitive layer performs on the green-sensitive layer. 
In order to enhance the interlayer effect from the red-sensitive layer to 
the green-sensitive layer, it would also be effective if at least one 
sub-layer of the red-sensitive layer or a layer adjacent thereto contains 
a compound which is cleaved upon reacting with the oxidation product of 
the color developing agent to form a cleaved product, which in turn 
cleaves the development inhibitor after a predetermined timing. 
It has been further found that the silver halide color photographic 
photosensitive material of the invention hardly turns green when exposed 
to the white light emitted from a fluorescent lamp of the commonly used 
type. 
The reason why the material hardly turns green remains unclear. 
Nevertheless, it is assumed that the magenta-colored cyan coupler absorbs 
light rays whose wavelengths overlaps the distribution of short-wave 
spectral sensitivity of the red-sensitive silver-halide emulsion layer, 
inevitably degrading the sensitivity of the red-sensitive emulsion layer, 
and, by removing or suppressing the magenta-colored cyan coupler, the 
spectral sensitivity distribution of the red-sensitive layer changes. 
Probably, this change in spectral sensitivity distribution synergistically 
works together with the interlayer effect applied on the green-sensitive 
layer, whereby the material hardly turns green when exposed to white 
light. 
Detailed description will now be made of the compound which is cleaved upon 
reacting with the oxidation product of the color developing agent to form a 
cleaved product, which in turn cleaves the development inhibitor upon 
reacting with another molecule of the oxidation product of the color 
development agent. This compound, which releases a development inhibitor 
and will be hereinafter referred to as "diffusible development inhibitor 
releasing compound," can be represented by any one of the following 
formulas:

##STR4## 
Any of the compounds [VI] to [IX] is contained in any layer of the 
photographic material, in an amount of 0.0001 to 0.1 mol per mol of 
silver, preferably 0.001 to 0.05 mol per mol of silver, more preferably 
0.005 to 0.05 mol per mol of silver, if that layer contains a silver 
halide emulsion. If the layer contains no silver halide emulsions, the 
compound can be contained in the layer in an amount falling within said 
range per mol of silver which is contained in a layer adjacent to that 
layer. 
The color photographic photosensitive material according to the invention 
comprises a support and at least one of each of three silver-halide 
emulsion layers formed on the support, which are blue-sensitive, 
green-sensitive, and red-sensitive, respectively. There is no limit to the 
number of silver-halide emulsion layers and non-photosensitive layers which 
constitute the photographic photosensitive material. A representative 
example of the material is one which comprises a support and at least one 
photosensitive layer formed of two or more silver-halide emulsion layers 
which have substantially the same color sensitivity but different 
photosensitivities or speeds. These emulsion layers are unit 
photosensitive layers each of which is sensitive to any of blue light, 
green light, and red light. Generally, in a multi-layer color photographic 
photosensitive material, the unit photosensitive layers are arranged such 
that a red-sensitive emulsion layer, a green-sensitive emulsion layer, and 
a blue-sensitive layer are formed in this order from the side of the 
support. Nevertheless, the order in which the emulsion layers are arranged 
can be reversed in accordance with the use of the photographic 
photosensitive material. Further, a different photosensitive layer can be 
sandwiched between two emulsion layers of the same color sensitivity. 
A non-photosensitive layer such as an interlayer can be interposed between 
any two silver-halide emulsion layers, and can be formed below the 
lowermost silver-halide emulsion photosensitive layer or on the uppermost 
silver-halide emulsion layer. 
The interlayer can contain a coupler, a DIR compound, and the like, 
disclosed in JP-A-61-43748, JP-A-59-113438, JP-A-59-113440, JP-A-61-20037, 
and JP-A-61-20038. Further, it can contain a color-mixing inhibitor which 
is commonly used in color photographic photosensitive materials. 
Preferably, a plurality of silver halide emulsion layers constituting the 
unit photosensitive layer comprises two sub-layers, i.e., a high-speed 
layer and a low-speed layer, as disclosed in, for example, West German 
Patent 1,121,470 and British Patent 923,045. Usually it is desirable that 
the low-speed layer be located closer to the support than the high-speed 
layer. A non-photosensitive layer can be interposed between the high-speed 
layer and low-speed layer. Conversely, the low-speed layer can be located 
farther from the support than the high-speed layer, as is disclosed in 
JP-A-57-112751, JP-A-62-200350, JP-A-62206541, and JP-A-62-206543. 
An actual example of the color photographic photosensitive material 
comprises a low-speed blue-sensitive layer (BL), a high-speed 
blue-sensitive layer (BH), a high-speed green sensitive layer (GH), a 
low-speed green-sensitive layer (GL), a high-speed red-sensitive layer 
(RH), and a low-speed red-sensitive layer (RL), arranged in this order 
from top down to the support. Another example is of a BH/BL/GL/GH/RH/RL 
structure. Still another example is of a BH/BL/GH/GL/RL/RH structure. 
Moreover, as is disclosed in JP-B-55-34932, the color photographic 
photosensitive material according to the invention can comprise a 
blue-sensitive layer, a GH layer, an RH layer, a GL layer, and an RL 
layer, arranged in this order from top down to the support. Further, as is 
disclosed in JP-A-56-25738 and JP-A-62-63936, the material can comprise a 
blue-sensitive layer, a GL layer, an RL layer, a GH layer, and an RH 
layer, arranged in this order from top down to the support. 
Still further, as is disclosed in JP-B-49-15495, the color photographic 
photosensitive material of the invention can have three silver-halide 
emulsion layers, wherein the upper layer is made of a high-speed emulsion, 
the intermediate layer is made of a medium-speed emulsion, and the lower 
layer is made of a low-speed emulsion. Even in this three-layer structure, 
each colorsensitive layer can comprise three sub-layers, i.e., a 
medium-speed layer, a high-speed layer, and a low-speed layer, arranged in 
this order from top down to the support. Alternatively, each 
color-sensitive layer can comprise a high-speed layer, a low-speed layer, 
and a medium-speed layer, arranged in this order from top down to the 
support, or can comprise a low-speed layer, a medium-speed layer, and a 
high-speed layer. 
Further, each of the color-sensitive layers of the photographic 
photosensitive material according to this invention can comprise four or 
more sub-layers. In this case, too, these sub-layers can be arranged in 
any of the alternative orders described above. 
In order to improve the color reproducibility of the color photographic 
photosensitive material, it is advisable to arrange, near each main 
photosensitive layer BL, GL or RL, a donor layer (CL) which differs in 
spectral sensitivity distribution from the main photosensitive layers and 
which applies interlayer effect thereto. Such donor layers are disclosed 
in U.S. Pat. Nos. 4,663,271, 4,705,744 and 4,707,436, JP-A-62-160448, 
JP-A-63-89850. 
As has been explained, various color sensitive layers can be used in 
various numbers, arranged in various orders, in accordance with the 
intended use of the silver halide color photographic photosensitive 
material. 
The silver halide contained in any photographic emulsion layer is 
preferably silver iodobromide, silver iodochloride, or iodochlorobromide, 
which contains about 30 mol % or less of silver iodide. More preferable is 
silver iodobromide or silver iodochlorobromide, which contains about 2 mol 
% to about 25 mol % of silver iodide. 
The silver halide grains in the emulsion can be regular crystals such as 
cubic grains, octahedral grains and tetradecahedral grains, irregular 
crystals such as spherical grains and tabular grains, or crystals having 
defects such as twinned crystal planes. Alternatively, the silver halide 
grains can be a mixture of these various crystals. 
The silver halide grains can be fine ones having a size of about 0.2 
microns or less, or large ones having a projected area diameter of up to 
about 10 microns. Further, the silver halide emulsions can either be 
monodispersed ones or polydispersed ones. 
The silver halide photographic emulsion for use in the present invention 
can be prepared by using methods described in, for example, Research 
Disclosure (RD), No. 17643 (1978, December), PP. 22 and 23, "I. Emulsion 
Preparation and Types", and RD No. 18716 (1979, November), P. 648; P. 
Glafkides, "Chimie et Phisique Photographique", Paul Montel, 1967; G. F. 
Duffin, "Photographic Emulsion Chemistry", Focal Press, 1966; and V. L. 
Zelikman et al., "Making and Coating Photographic Emulsion", Focal Press, 
1964. 
Monodispersed emulsions described in, e.g., U.S. Pat. Nos. 3,574,628 and 
3,655,394, and British Patent 1,413,748 are also preferable. 
A tabular grain having an aspect ratio of about 5 or more can be used in 
the present invention. The tabular grain can be easily prepared by methods 
described in, e.g., Gutoff, "Photographic Science and Engineering", Vol. 
14, PP. 248 to 257 (1970); U.S. Pat. Nos. 4,434,226, 4,414,310, 4,433,048, 
and 4,439,520, and British Patent 2,112,157. 
A crystal structure may be uniform, may have different compositions of 
halogen in its inner and outer portions, or may be a layered structure. 
Alternatively, silver halides having different compositions may be bonded 
together by an epitaxial junction, or a compound other than a silver 
halide such as silver rhodanate or zinc oxide may be bonded to silver 
halide. In addition, a mixture of grains having various crystal shapes can 
be used. 
The silver halide emulsion is normally subjected to physical ripening, 
chemical ripening, and spectral sensitization, and then used. Additives 
used in these steps are described in Research Disclosure Nos. 17643 and 
18716, and they are summarized below. 
It is desirable that fine grains of nonphotosensitive silver halide be used 
in the present invention. The non-photosensitive silver halide does not 
sense light when imagewise exposed to light to form a dye image, and is 
not substantially developed during the development process. Preferably, 
the grains of the non-photosensitive silver halide are not fogged 
beforehand. 
The non-photosensitive silver halide fine grains contain 0 to 100 mol % of 
silver bromide. They can contain silver chloride and/or silver iodide, if 
necessary. Preferably, they contain 0.5 to 10 mol % of silver iodide. 
The fine grains of the non-photosensitive silver halide have an average 
diameter (i.e., an average of circle equivalent, projected area diameter) 
of 0.01 to 0.5 .mu.m, preferably 0.02 to 0.2 .mu.m. 
The non-photosensitive silver halide fine grains can be prepared by the 
same method as that of preparing ordinary photosensitive silver halide 
grains. The surface of each silver halide grain need not be sensitized 
optically. Nor do they need to be sensitized spectrally. It is desirable, 
however, that a known stabilizer such as a triazole compound, an azaindene 
compound, a benzothiazolium compound, a mercapto compound, or a zinc 
compound be added thereto, prior to the addition to a coating solution. 
Conventional photographic additives for use in the present invention are 
also described in the above two RDs and listed in the Table below.

In order to prevent degradation in photographic properties caused by 
formaldehyde gas, a compound which can react with and set formaldehyde 
described in U.S. Pat. Nos. 4,411,987 or 4,435,503 is preferably added to 
the photosensitive material.

4,004,929 and 4,138,258, and British Patent 1,146,368. 
It is advisable to use a coupler disclosed in U.S. Pat. No. 4,774,181 which 
releases a fluorescent dye at the time of coupling, the fluorescent dye 
correcting unnecessary absorption of a colored dye, or a coupler disclosed 
in U.S. Pat. No. 4,777,120 which contains, as a releasing group, a

The couplers for use in this invention can be introduced in the 
photosensitive materials by various known dispersion methods. 
Examples of a high-boiling solvent used in an oil-in-water dispersion 
method are described in, e.g., U.S. Pat. No. 2,322,027. 
Examples of a high-boiling organic solvent to be used in the oil-in-water 
dispersion method and having a boiling point of 175.degree. C. or more at 
normal pressure are phthalate esters (e.g., dibutylphthalate, dicyclohexyl 
phthalate, di-2-ethylhexyl phthalate, decyl phthalate, 
bis(2,4-di-t-amylphenyl) phthalate, bis(2,4-di-t-amylphenyl) isophthalate, 
and bis(1,1-di-ethylpropyl) phthalate), phosphate or phosphonate esters 
(e.g., triphenyl phosphate, tricresyl phosphate, 
2-ethylhexyldiphenylphosphate, tricyclohexylphosphate, 
tri-2-ethylhexylphosphate, tridodecylphosphate, tributoxyethylphosphate, 
trichloropropylphosphate, and di-2-ethylhexylphenylphosphonate), benzoate 
esters (e.g., 2-ethylhexyl benzoate, dodecyl benzoate, and 
2-ethylhexyl-p-hydroxybenzoate), amides (e.g., N,N-diethyldodecaneamide, 
N,N-diethyllaurylamide, and N-tetradecylpyrrolidone), alcohols or phenols 
(e.g., isostearylalcohol and 2,4-di-tert-amylphenol), aliphatic 
carboxylate esters (e.g., bis(2-ethylhexyl)sebacate, dioctylazelate, 
glyceroltributyrate, isostearyllactate, and trioctylcitrate), aniline 
derivatives (e.g., N,N-dibutyl-2-butoxy-5-tert-octylaniline), and 
hydrocarbons (e.g., paraffin, dodecylbenzene, and diisopropylnaphthalene). 
An organic solvent having a boiling point of about 30.degree. C. or more, 
and preferably, 50.degree. C. to about 160.degree. C. can be used as a 
co-solvent. Typical examples of the co-solvent are ethyl acetate, butyl 
acetate, ethyl propionate, methylethylketone, cyclohexanone, 2-ethoxyethyl 
acetate, and dimethylformamide. 
Steps and effects of a latex dispersion method and examples of an 
impregnating latex are described in, e.g., U.S. Pat. No. 4,199,363 and 
west German Patent Application (OLS) Nos. 2,541,274 and 2,541,230. 
Preferably, the color photographic photosensitive material according to the 
invention contains phenethyl alcohol, an antiseptic agent, or an antifungal 
agent. Examples of the antiseptic agent and the antifungal agent are: 
1,2-benzisochiazoline-3-one, n-butyl-p-hydroxybenzoate, phenol, 
4-chloro-3,5-dimethylphenol, 2-phenoxyethanol, 2-(4-thiazolyl) 
benzimidazole disclosed in JP-A-63-257747, JP-A-62-272248, JP-A-1-80941. 
The present invention can be applied to various color photosensitive 
materials. Examples of the material are a color negative film for a 
general purpose or a movie, a color reversal film for a slide or a 
television, color paper, a color positive film, and color reversal paper. 
Examples of a support suitable for use in this invention are described in 
the above-mentioned RD. No. 17643, page 28 and ibid., No. 18716, page 647, 
right column to page 648, left column. 
The hydrophilic colloid layers in the color photographic photosensitive 
material according to the invention preferably have a total thickness of 
28 .mu.m or less, more preferably 23 .mu.m or less, most preferably 16 
.mu.m or less. It is preferred that the hydrophilic colloid layers has a 
swelling speed T.sub.1/2 of 30 seconds or less, preferably 20 seconds or 
less. The thickness of the colloid layers is one measured after these 
layers had been left to stand for two days at 25.degree. C. at relative 
humidity of 55%. The swelling speed T.sub.1/2 can be measured by the 
techniques known in the art, by means of, for example, a swellometer of 
the type which A. Green et al. describe in Photographic Science and 
Engineering, Vol. 19, No. 2, pp. 124-129. The swelling speed T.sub.1/2 is 
the period of time which a colloid layer requires to swell to half the 
saturated thickness, i.e., 90% of the maximum swollen thickness when it is 
immersed in a color developing liquid at 30.degree. C. for 3 minutes and 15 
seconds. 
The swelling speed T.sub.1/2 can be adjusted by adding a proper amount of a 
hardening agent to gelatin which is used as a binder, or by changing the 
conditions under which each colloid layer is allowed to age after it has 
been coated. It is desirable that each hydrophilic colloid layer be 
swollen to a swelling ratio of 150 to 400%, said swelling ratio calculated 
as follows: 
EQU (Tmax-T)/T 
where T is the thickness of the colloid layer mentioned above, and Tmax is 
the maximum swollen thickness the layer can have when treated under the 
above-mentioned conditions. 
The color photographic photosensitive materials of the present invention 
can be developed by the ordinary processes as described, for example, in 
the above-described Research Disclosure, No. 17643, pages 28 and 29 and 
ibid., No. 18716, page 651, left to right columns. 
A color developer used in developing of the photosensitive material of the 
present invention is an aqueous alkaline solution mainly consisting of, 
preferably, an aromatic primary amine-based color developing agent. As the 
color developing agent, although an aminophenol compound is effective, a 
p-phenylenediamine compound is preferably used. Typical examples of the 
p-phenylenediamine compound are 3-methyl-4-amino-N,N-diethylaniline, 
3-methyl-4-amino-Nethyl-N-.beta.-hydroxyethylaniline, 
3-methyl-4-amino-N-ethyl-N-.beta.-methanesulfonamidoethylaniline, 
3-methyl-4-amino-N-ethyl-.beta.-methoxyehtylaniline, and sulfates, 
hydrochlorides and p-toluenesulfonates thereof. Of these, the most 
preferable is a sulfate salt of 
3-methyl-4-amino-N-ethyl-N-.beta.-hydroxyethylaniline. These compounds can 
be used in a combination of two or more thereof in accordance with 
applications. 
In general, the color developer contains a pH buffering agent such as 
carbonate salts, borate salts or phosphate salts of an alkali metal, and a 
development restrainer or antifoggant such as bromides, iodides, 
benzimidazoles, benzothiazoles or mercapto compounds. If necessary, the 
color developer may also contain a preservative such as hydroxylamine, 
diethylhydroxylamine, a hydrazine sulfite, a phenylsemicarbazide, 
triethanolamine, a catechol sulfonic acid or a 
triethylenediamine(1,4-diazabicyclo[2,2,2]octane); an organic solvent such 
as ethyleneglycol or diethyleneglycol; a development accelerator such as 
benzylalcohol, polyethyleneglycol, a quaternary ammonium salt or an amine; 
a dye forming coupler; a competing coupler; an auxiliary developing agent 
such as 1-phenyl-3-pyrazolidone; a viscosity imparting agent; and a 
chelating agent such as an aminopolycarboxylic acid, an 
aminopolyphosphonic acid, an alkylphosphonic acid or a phosphonocarboxylic 
acid. Examples of the chelating agent are ethylenediaminetetraacetic acid, 
nitrilotriacetic acid, diethylenetriaminepentaacetic acid, 
cyclohexanediaminetetraacetic acid, hydroxyethyliminodiacetic acid, 
1-hydroxyethylidene-1,1-diphosphonic acid, 
nitrilo-N,N,N-trimethylenephosphonic acid, 
ethylenediamine-N,N,N',N'-tetramethylenephosphonic acid and 
ethylenediamine-di(o-hydroxyphenylacetic acid) and salts thereof. 
In order to perform reversal development, black-and-white development is 
performed and then color development is performed. As a black-and-white 
developer, well-known black-and-white developing agents, e.g., a 
dihydroxybenzene such as hydroquinone, a 3-pyrazolidone such as 
1-phenyl-3-pyrazolidone, and an aminophenol such as N-methyl-p-aminophenol 
can be used singly or in a combination of two or more thereof. 
The pH of the color and black-and-white developers is generally 9 to 12. 
Although a quantity of replenisher of the developer depends on a color 
photographic light-sensitive material to be processed, it is generally 3 
liters or less per m.sup.2 of the photosensitive material. The quantity of 
replenisher can be decreased to be 500 ml or less by decreasing a bromide 
ion concentration in a replenisher. In order to decrease the quantity of 
replenisher, the contact area of a processing solution in a processing 
tank with air is preferably decreased to prevent evaporation and oxidation 
of the solution upon contact with air. 
The area in which the photographic treating liquid contacts air in a 
treatment bath can be represented by an opening ratio which is obtained by 
dividing the liquid-air contact area (cm.sup.2) by the volume (cm.sup.3) of 
the treatment liquid. The opening ratio is preferably, 0.1 or less, more 
preferably 0.001 to 0.05. To reduce the opening ratio to a value falling 
within this range, a shield, such as a floating cover, can be placed on 
the surface of the treatment liquid in the bath. Another method is to use 
a movable cover of the type disclosed in JP-A-1-82033. Another alternative 
is the slit development disclosed in JP-A-62-216050. It is advisable to 
reduce the opening ratio, not only in the color development process and 
the black-and-white development process, but also in all other processes 
such as bleaching, bleach-fixing, fixing, water-washing, and 
stabilization. 
The quantity of replenisher can be decreased by suppressing the 
accumulation of bromide ions in the developer. 
A color development time is normally set between 2 to 5 minutes. The 
processing time, however, can be shortened by setting a high temperature 
and a high pH and using the color developing agent at a high 
concentration. 
The photographic emulsion layer is generally subjected to bleaching after 
color development. The bleaching may be performed either simultaneously 
with fixing (bleach-fixing) or independently thereof. In addition, in 
order to increase the processing speed, bleach-fixing may be performed 
after bleaching. Also, processing may be performed in a bleach-fixing bath 
having two continuous tanks, fixing may be performed before bleach-fixing, 
or bleaching may be performed after bleach-fixing, in accordance with 
applications. Examples of the bleaching agent are a compound of a 
multivalent metal such as iron (III); a peroxide; a quinone; and a nitro 
compound Typical examples of the bleaching agent include an organic 
complex salt of iron (III), e.g., a complex salt of an aminopolycarboxylic 
acid such as ethylenediaminetetraacetic acid, diethylenetriaminepentaacetic 
acid, cyclohexanediaminetetraacetic acid methyliminodiacetic acid, 
1,3-diaminopropanetetraacetic acid, and glycoletherdiaminetetraacetic 
acid, or a complex salt of citric acid, tartaric acid or malic acid. Of 
these compounds, iron (III) complex salts of aminopolycarbosylic acid 
including iron (III) complex salts of ethylenediaminetetraacetic acid and 
1,3-diaminopropanetetraacetic acid are preferred because they can increase 
a processing speed and prevent an environmental contamination. The iron 
(III) complex salt of aminopolycarboxylic acid is effective in both the 
bleaching and bleach-fixing solutions. The pH of the bleaching or 
bleach-fixing solution containing the iron (III) complex salt of 
aminopolycarboxylic acid is normally 4.0 to 8. In order to increase the 
processing speed, however, processing can be performed at a lower pH. 
A bleaching accelerator can be used in the bleaching solution, the 
bleach-fixing solution and their prebath, if necessary. Examples of 
effective bleaching accelerators are compounds having a mercapto group or 
a disulfide group described in, e.g., U.S. Pat. No. 3,893,858, West German 
Patents 1,290,812 and 2,059,988, JP-A-53-32736, JP-A-53-57831, 
JP-A-53-37418, JP-A-53-72623, JP-A-53-95630, JP-A-53-95631, 
JP-A-53-104232, JP-A-53-124424, JP-A-53-141623, and JP-A-53-28426, and RD 
No. 17129 (July, 1978); thiazolidine derivatives described in 
JP-A-50-140129; thiourea derivatives described in JP-B-45-8506, 
JP-A-52-20832 and JP-A-53-32735, and U.S. Pat. No. 3,706,561; iodide salts 
described in West German Patent 1,127,715 and JP-A-58-16235; 
polyoxyethylene compounds described in West German Patents 966,410 and 
2,748,430; a polyamine compound described in JP-B-45-8836; compounds 
described in JP-A-49-42434, JP-A-49 -59644, JP-A-53-94927, JP-A-54-35727, 
JP-A-55-26506, and JP-A-58-163940; and a bromide ion. The compounds having 
a mercapto or disulfide group are preferred since they have a large 
accelerating effect. Of these, the compounds described in U.S. Pat. No. 
3,893,858, West German Patent 1,290,812, and JP-A-53-95630 are 
particularly preferred. The compound described in U.S. Pat. No. 4,552,834 
is also preferred. These bleaching accelerators may be added in the 
photosensitive material. These bleaching accelerators are effective 
especially in bleach-fixing of a colorphotosensitive material for picture 
taken with camera. 
Preferably, the bleaching solution and the bleach-fixing solution contain, 
besides the compounds specified above, an organic acid for preventing 
bleaching stain. Desirable as organic acid is a compound whose 
acid-dissociation constant (pKa) ranges from 2 to 5. More specifically, 
acetic acid and propionic acid are preferable. 
Examples of the fixing agent which is contained in the fixing solution or 
the bleach-fixing solution are: a thiosulfate salt, a thiocyanate salt, a 
thioether compound, a thiourea, and a large amount of iodide. 0f these 
compounds, a thiosulfate salt, especially ammonium thiosulfate, can be 
used in a widest range of application. It is also desirable that a 
thiosulfate salt be used in combination with a thiocyanate salt, a 
thioether compound, or a thiourea. As a preservative of the fixing 
solution or the bleach-fixing solution, a sulfite salt, a bisulfite salt, 
or a carbonyl bisulfite adduct, or a sulfinic acid compound disclosed in 
European Patent 294769A is preferred. Further, it is desirable that the 
fixing solution and the bleach-fixing solution contain aminopolycarboxylic 
acids or organic sulfonic acids, which stabilize the solution. The total 
time of desilvering should be as short as possible, but should be long 
enough to perform the desilverization sufficiently. The total desilvering 
time is preferably 1 to 2 minutes. It is advisable to perform the 
desilverization at a temperature ranging from 25.degree. C. to 50.degree. 
C., preferably 35.degree. C. to 45.degree. C. When performed at any 
temperature falling within this range, the desilvering will be 
accelerated, and stain generation will be effectively prevented. 
It is recommendable that the stirring be performed as vigorously as 
possible in the desilvering step. To achieve vigorous stirring, a liquid 
jet can be applied to the emulsion surface of the photographic material as 
is disclosed in JP-A-62-183461, or the solution bath can be rotated as is 
taught in JP-A-62-183461. Another method of vigorously stirring the 
treating solution is to move the photographic material immersed in the 
bath, with its emulsion surface kept in contact with a wiper blade also 
immersed in the bath, causing a turbulent flow over the emulsion surface. 
Still another alternative is to increase the amount of the treating 
solution circulating within the bath, thereby intensifying the stirring. 
Any of the stirring methods described above is efficient for the bleaching 
solution, the bleach-fixing solution, and the fixing solution. The 
vigorous stirring of the solution, thus accomplished, is believed to 
accelerate the supply of the bleaching agent or the fixing agent into the 
emulsion layer, thus increasing the desilvering speed. The methods can be 
effectively used in combination with the use of the bleaching accelerator, 
helping to accelerate the bleaching or preventing the bleaching accelerator 
from hindering the fixing. 
The automatic developing machine which may be used for the color 
photographic photosensitive material of the the present invention should 
preferably have a transporting means of the type disclosed in 
JP-A-60-1911257, JP-A-60-191258, and JP-A-60-191259. If equipped with such 
a transporting means, the machine can greatly decrease the amount of the 
solution taken from the pre-bath to the after-bath, thereby maintaining 
the ability of the solution at a sufficiently high level. Since the 
solution preserves high ability, each photographing step can be completed 
within a short time, and the quantity of replenishing solution may be 
small. 
The photographic photosensitive material of the present invention is 
normally subjected to washing and/or stabilizing steps after desilvering. 
An amount of water used in the washing step can be determined over a broad 
range in accordance with the properties of the photosensitive material 
(e.g., a property determined by the substances used such as couplers), the 
application of the material, the temperature of the washing water, the 
number of water tanks (the number of stages), a replenishing scheme 
representing a counter or forward current, and other conditions. The 
relationship between the amount of water and the number of water tanks in 
a multi-stage counter-current scheme can be obtained by a method described 
in "Journal of the Society of Motion Picture and Television Engineers", 
Vol. 64, PP. 248-253 (May, 1955). 
According to the above-described multi-stage counter-current scheme, the 
amount of water used for washing can be greatly decreased. Since washing 
water stays in the tanks for a long period of time, however, bacteria 
multiply and the produced floating substances may be undesirably attached 
to the photosensitive material. In order to solve this problem in the 
process of the color photographic photosensitive material of the present 
invention, a method of decreasing calcium and magnesium ions can be 
effectively utilized, as described in JP-A-62-288838. In addition, a 
germicide such as an isothiazolone compound and cyabendazole described in 
JP-A-57-8542, a chlorine-based germicide such as chlorinated sodium 
isocyanurate, and germicides such as benzotriazole described in Hiroshi 
Horiguchi, "Chemistry of Antibacterial and Antifungal Agents", 1986, 
published by Sankyo Shuppan, Eiseigijutsu-Kai ed., "Sterilization, 
Antibacterial, and Antifungal Techniques for Microorganisms", 1982, 
published by Kogyo Gijutsukai, and Nippon Bokin Bobabi Gakkai ed., 
"Dictionary of Antibacterial and Antifungal Agents", 1986. 
The pH of the water for washing the photographic photosensitive material of 
the present invention is 4 to 9, and preferably, 5 to 8. The water 
temperature and the washing time can vary in accordance with the 
properties and applications of the photosensitive material. Normally, the 
washing time is 20 seconds to 10 minutes at a temperature of 15.degree. C. 
to 45.degree. C., and preferably, 30 seconds to 5 minutes at 25.degree. C. 
to 40.degree. C. The photosensitive material of the present invention can 
be processed directly by a stabilizer in place of washing. All known 
methods described in JP-A-57-8543, JP-A-58-14834, and JP-A-60-220345 can 
be used in such stabilizing process. 
Stabilization is performed in some cases, after the water-washing. The 
stabilization is performed in a stabilizing bath containing, for example, 
a dye-stabilizing agent and a surface-active agent. This stabilizing bath 
is used as a final bath of the color photographic photosensitive material 
for use in taking pictures by a camera. Examples of the dye-stabilizing 
agent are aldehydes such as formalin and glutaraldehyde, N-methylol 
compounds, hexamethylenetetramine, or an aldehyde sulfite adduct. 
Various cheleting agents or various antifungal agents can be added to the 
stabilizing bath. 
An overflow solution produced upon washing and/or replenishment of the 
stabilizing solution can be used again in another step such as 
desilvering. 
The treatment solutions described above may condense as the solvents 
evaporate while the solutions are being used in the automatic developing 
machine. If this is the case, it is preferred that water is added to the 
solutions, thereby adjusting the concentrations thereof. 
The silver halide color photographic photosensitive material of the present 
invention may contain a color developing agent in order to simplify 
processing and increase a processing speed. In order to incorporate the 
color developing agent in the photosensitive material, various precursors 
of the color developing agent are preferably used. Examples of the 
precursor are an indoaniline-based compound described in U.S. Pat. No. 
3,342,597; Schiff base compounds described in U.S. Pat. No. 3,342,599 and 
Research Disclosure Nos. 14,850 and 15,159; an aldol compound described in 
RD No. 13,924; a metal complex salt described in U.S. Pat. No. 3,719,492; 
and a urethane-based compound described in JP-A-53-135628. 
The silver halide color photosensitive material of the present invention 
may contain various 1-phenyl-3-pyrazolidones in order to accelerate color 
development, if necessary. Typical examples of the compound are described 
in JP-A-56-64339, JP-A-57-144547, and JP-A-58-115438. 
Each processing solution used in the present invention is used at a 
temperature of 10.degree. C. to 50.degree. C. Although a normal processing 
temperature is 33.degree. C. to 38.degree. C., processing may be 
accelerated at a high temperature to shorten a processing time, or image 
quality or stability of a processing solution may be improved at a lower 
temperature. 
The color photographic photosensitive material of the invention can also be 
applied to thermal development photosensitive materials of the types 
described in U.S. Pat. No. 4,500,625, JP-A-60-133449, JP-A-59-218443, 
JP-A-61-238056, and European Patent 210,660A2. 
If the photosensitive material according to the present invention is used 
in the form of a roll, it should better be contained in a cartridge. The 
cartridge, which is most popular at present is a 135-format patrone. Also, 
use can be made of the cartridges disclosed in JU-A-58-67329 and 
JU-A-58-195236 ("JU-A" means Published Unexamined Japanese Utility Model 
Application). Further, use can be made of the cartridges disclosed in 
JP-A-58-181035, JP-A-58-182634, U.S. Pat. Nos. 4,221,479, 4,846,418, 
4,848,693, and 4,832,275, JP-A-1-231045, JP-A-2-124565, JP-A-2-170156,

The present invention will be described in greater detail, with reference 
to the following examples. Nonetheless, the invention is not limited to 
these examples.

Layers 2 and 3 of sample 101 were modified as follows: 
a. Layer 2 
ExC-2: Added in an amount of 0.07 g/m.sup.2 
ExC-3: Changed from 0.26 to 0 
b. Layer 3 
ExC-2: Added in amount of 0.02 
ExC-3: Changed from 0.12 to 0 
Samples 101 to 107, thus prepared, were subjected to wedge exposure by 
using white light (C light source), and then to development which will be 
described later. Further, the densities of the samples, thus developed, 
were measured by means of the density detector (i.e., a status M filter) 
manufactured by Macbeth Co., Ltd. Samples 101 to 107 exhibited very 
similar sensitometry curves, indicating that the samples had almost 
identical sensitivity gradations for all color-filter densities, except 
green-filter density. 
Using the seven samples, a red rose with leaves were photographed under the 
same conditions. The samples were so processed, that images of the rose 
were printed from the processed samples onto Fuji-Color Paper Super HG 
(tradename) such that the prints had gray background of the same density. 
Five experts evaluated the hue of red-petal image and that of green-leaf 
image on each print. Each expert gave two points to an excellent red-petal 
image, one point to a good red-petal image, and no points to a poor 
red-petal image; he or she gave two points to an excellent green-leaf 
image, one point to a good green-leaf image, and no points to a poor 
green-leaf image. The total points the five experts gave to the red-petal 
and green-leaf images of each print were divided by 5, thereby evaluating 
each sample of the color photographic photosensitive material. The results 
were as is shown in Table 1.

______________________________________ 
As is evident from Table 1, the hues of the red petals and green leaves 
reproduced by samples 102 and 105, both of the present invention, were 
evaluated at a value over the average of 1.0. This means that the five 
experts recognized that samples 102 and 105 had excellent color 
reproducibility, and hence the advantages of the present invention.
