FIELD OF THE INVENTION 
The present invention relates to a silver halide photosensitive material, 
and particularly to a silver halide color photosensitive material which is 
protected from a fading of a yellow color image. 
BACKGROUND OF THE INVENTION 
It has been well known that a silver halide color photosensitive material 
forms a dye image by an imagewise exposure of the photosensitive material 
to light and a color development of the material. The dyes in the obtained 
image, such as indophenol, indoaniline, indamine, azomethine, phenoxazine 
and phenazine dyes are formed by a reaction of an oxidized aromatic 
primary amine color developing agent with a coupler in the color 
development. 
In general, the quality of the obtained photographic image is not 
perpetual, and is gradually degraded while the photograph is preserved. A 
color photograph having an image made of an azomethine or indoaniline dye 
is particularly apt to be degraded. The degradation of the image is caused 
by a fading or discoloration of the dye image or a discoloration on a 
white ground (yellow stain), when the photograph is irradiated with light 
for a long term, or preserved at a high temperature and humidity. 
The degradation of the image quality is a serious disadvantage. An 
improvement is desirable to overcome the disadvantage. 
A color photograph generally contains cyan, magenta and yellow dye images. 
Each of the dye images has been independently investigated to stabilize 
the photograph. The magenta dye image has been particularly well 
investigated. The yellow dye image has not been so well investigated as 
the magenta dye image, since the yellow dye image was relatively stable 
compared with the magenta dye image. However, the stability of the magenta 
dye image has recently been so much improved as the results of the 
investigation that a fading or discoloration of the yellow dye image now 
becomes remarkable. Accordingly, it is now desirable to stabilize the 
yellow dye image. 
The use of a color image stabilizer has been proposed to improve the 
stability of the yellow dye image to light, heat or humidity. For example, 
hindered amine derivatives and phenol derivatives are disclosed in U.S. 
Pat. Nos. 4,452,884 and No. 4,465,765, and Japanese Patent Provisional 
Publications No. 54(1979)-48535, No. 59(1984)-3433, No. 59(1984)-5246, No. 
59(1984)-87456, No. 61(1986)-2151 and No. 61(1986)-86750; spirochroman 
derivatives are disclosed in Japanese Patent Publication No. 
59(1984)-52825; and amines other than hydrazines are disclosed in Japanese 
Patent Provisional Publications No. 63(1988)-149642, No. 63(1988)-149643, 
No. 63(1988)-149645 and No. 63(1988)-163347. 
In order to improve the stability of a yellow dye to light or heat, the 
compounds disclosed in the above-mentioned publications have an effect on 
the dye to some extent. However, the effect is relatively weak or is 
accompanied by a bad effect on the quality of the photograph. 
Further, the use of hydrazine derivatives is proposed in European Patent 
No. 255,722 and Japanese Patent Provisional Publication No. 
63(1988)-220142. The compounds disclosed in European Patent No. 255,722 
react with a developing agent which remains in a color photosensitive 
material after the development process to remove the remaining developing 
agent, which causes a fading. Accordingly, the effect of these compounds 
on dyes to prevent the fading is weak because they do not directly reacts 
with the dyes. The compounds disclosed in Japanese Patent Provisional 
Publication No. 63(1988)-220142 have some bad influences on the the 
quality of the photograph. For example, they inhibit the color development 
reaction of a coupler or cause a fog within the unexposed area. 
In contrast to the yellow dye image, various color image stabilizers have 
been proposed to improve the stability of the magenta dye image. Most of 
the color image stabilizers do not have any effect on the yellow dye 
image, and has the effect only on the magenta dye image. Moreover, many of 
the color image stabilizers adversely accelerate the fading of the yellow 
dye image. 
SUMMARY OF THE INVENTION 
An object of the present invention is to provide a silver halide color 
photosensitive material which is improved in the stability of the yellow 
dye image. 
Another object of the invention is to provide a silver halide color 
photosensitive material in which the yellow image can be stabilized by 
incorporating into a photographic layer a stabilizer which has a 
sufficient effect on the yellow dye image to improve the stability of the 
image without any of the change of hue, the occurrence of fog, the bad 
influence on disperse phase and the crystallization. 
A further object of the invention is to provide a silver halide color 
photosensitive material which is improved in the color balance with 
respect to the fading of three colors by the improvement of the stability 
of the yellow dye image to light or heat. 
In the course of studies of the present inventors, it is found that the 
above-mentioned objects are attained by a silver halide color 
photosensitive material of the present invention, which comprises a

SYNTHESIS EXAMPLE 1 
Synthesis of Yellow Coupler (Y-5) 
In 240 ml of dimethylacetamide and 210 ml of acetonitrile were dissolved 44 
g of 
.alpha.-chloro-.alpha.-pivaloyl-2-chloro-5-(n-hexadecanesulfonamido)acetoa 
nilide and 112 g of 3,3'-dichloro-4,4'-dihydroxydiphenylsulfone under 
reflux. 
To the solution was dropwise added 9.7 ml of triethylamine, and the 
reaction proceeded for 5 hours under reflux. 
The reaction mixture was poured into 500 ml of sodium hydroxide, and 
extracted with 300 ml of ethyl acetate. 
The oily phase was twice washed with water, dried on magnesium sulfate, and 
concentrated under reduced pressure to obtain a residue. 
The residue was chromatographed over silica gel, and the fraction 
containing a reaction product was concentrated under reduced pressure. The 
residue was crystallized in n-hexane/ethanol (10/1 as volume ratio) to 
obtain 45 g of the above-mentioned coupler (Y-5). The melting point was 
91.degree. to 93.degree. C.

while stirring at 10.degree. to 15.degree. C. The mixture was further 
stirred at 20.degree. to 25.degree. C. for 1 hour. The reaction mixture 
was poured into 200 ml of ice-cold water, and extracted with 200 ml of 
ethyl acetate. The oily phase was twice washed with water, dried on salt 
cake, and concentrated under reduced pressure. The residue was 
crystallized in 150 ml of methanol. The crystal was filtered off, and 
purified by column chromatography to obtain 25 g of the above-mentioned 
compound (A-4) as an oily substance. 
Synthesis of Compound (A-13) 
To 15.3 g of the compound (A.4) were added 30 ml of dimethylacetamide, 30 
ml of acetonitrile and 8 ml of triethylamine.To the mixture was dropwise 
added 15.0 g of 2,4-di-tert-amylphenoxyacetylchloride while stirring at 
10.degree. to 15.degree. C. The mixture was further stirred at 20.degree. 
to 25 .degree. C. for 30 minutes. The reaction mixture was poured into 200 
ml of ice-cold water, and extracted with 200 ml of ethyl acetate. The oily 
phase was twice washed with water, dried on salt cake, and concentrated 
under reduced pressure. The residue was crystallized in 200 ml of 
methanol. The crystal was filtered off, and washed with cold methanol to 
obtain 18.5 g of the above-mentioned compound (A-13). The melting point 
was 122.degree. to 124.degree. C. 
Some of the compounds having the formula [I] are described in Japanese 
Patent Provisional Publications No. 62(1987)-270954 and No. 63(1988)-43145 
as a color image stabilizer for a magenta coupler. Some of the compounds 
having the formula [II] are also described in Japanese Patent Provisional 
Publications No. 63(1988)-43145 and No. 63(1988)-115866 and Japanese 
Patent Publication No. 60(1985)-47573 as a color image stabilizer for a 
magenta coupler. But, the color image stabilizers for a magenta coupler do 
not always have any effect on a yellow coupler. 
The present inventors have found that the compound having the formula [I] 
or [II] shows a remarkable effect on the dye image formed by a yellow 
coupler. The effect is to improve the stability of the yellow image to 
heat or light without a bad effect on the quality of the photograph. 
The amount of the compound [I] or [II] is depend on the nature of the 
coupler used in combination. The amount is in the range of 5 to 400 mole % 
based on 1 mole of the coupler, and preferably in the range of 10 to 200 
mole %. If the amount is smaller than this range, the effect is too small 
for practical use. If the amount is larger than the range, the color 
density may be decreased by an inhibition of a development reaction. 
The compounds having the formula [I] or [II] can be used singly or in 
combination of two or more compounds. Further, the compounds may be used 
in combination with known color image stabilizers. 
Examples of the known color image stabilizers include phenols, hindered 
amines, phosphate esters, hydrazines and complexes. These known color 
image stabilizers are described in Japanese Patent Provisional 
Publications No. 58(1983)-14036, No. 59(1984)-5426 and No. 61(1986)-2151, 
Japanese Patent Publications No. 62(1987)-28182, No. 48(1973-31256, No. 
51(1976)-1420 and No. 52(1977)-6623, British Patents No. 1,326,889, No. 
1,354,313 and No. 1,410,846, U.S. Pat. Nos. 3,335,135 and No. 4,268,593, 
and European Patents No. 246,766 and No. 265,196. 
According to the present invention, the compound having the formula [I] or 
[II] is used in the layer containing a yellow coupler in such manner that 
the compound and the yellow coupler are together contained in droplets of 
a medium which are dispersed in the layer. The medium preferably is an 
organic solvent having a high boiling point. 
The color photosensitive material of the present invention preferably 
comprises a blue sensitive silver halide emulsion layer, a green sensitive 
silver halide emulsion layer and a read sensitive silver halide emulsion 
layer on a support in the order. This order may be changed. 
Examples of the silver halide used in the present invention include silver 
chloride, silver bromide, silver iodide, silver chloro(iodo)bromide and 
silver iodobromide. Silver chloride and silver chloro(iodo)bromide are 
particularly preferred. With respect to the halogen composition, the 
silver halide grains contained in an emulsion layer preferably are silver 
chlorobromide which substantially does not contain silver iodide and 
contains silver chloride in an amount of not less than 90 moles % based on 
the total amount of the silver halide. The term "substantially does not 
contain silver iodide" means that the iodide content is not more than 1.0 
mole %. It is more preferred that the silver halide grains contained in an 
emulsion layer preferably are silver chlorobromide which substantially 
does not contain silver iodide and contains silver chloride in an amount 
of not less than 95 mole % based on the total amount of the silver halide. 
The silver halide grains preferably have a phase where silver bromide is 
localized in an amount of 10 mole % to 70 mole %. The silver bromide 
localized phase may be arranged in the inside, surface or subsurface of 
the silver halide grains. The localized phase may be also divided into the 
inside, surface or subsurface. Further, the localized phase may have a 
layered structure surrounding the silver halide grain or have a 
discontinuous structure in the inside or surface of the grain. A preferred 
example of the arrangement of the silver bromide localized phase is that 
the localized phase containing silver bromide in an amount of not less 
than 10 mole % (more preferably not less than 20 mole %) is epitaxially 
formed in the surface of (particularly an edge of) the silver halide 
grain. 
It is more preferred that the localized phase contains silver bromide in an 
amount of not less than 20 mole %. If the content of silver bromide is 
relatively high, the localized phase sometimes affects the quality of the 
photosensitive material. In more detail, if the silver bromide content is 
high, the sensitivity of the photosensitive material tends to be lowered 
when pressure is applied to the material, and the sensitivity or gradation 
of the photosensitive material may be markedly changed according to the 
change of the composition of a processing solution. Accordingly, the 
silver bromide content in the localized phase more preferably is in the 
range of 20 to 60 mole %, and most preferably in in the range of 30 to 60 
mole %. The silver halide other than the localized phase preferably is 
silver chloride. The silver bromide content in the localized phase can be 
analyzed by X-ray analysis or XPS (X-ray photoelectron spectroscopy). The 
localized phase preferably has a silver content in the range of 0.1 to 20% 
(more preferably 0.5 to 7 %) based on the total silver content. 
The interface between the silver bromide localized phase and the other 
phase may be either a clear boundary or a transition area where the 
halogen composition is gradually changed. The position of the the silver 
bromide localized phase can be observed by an electron microscope or a 
method described in European Patent Provisional Publication No. 273430A2. 
The above-mentioned silver bromide localized phase can be formed by various 
methods. For example, the localized phase can be formed by a reaction of a 
soluble silver salt with a soluble halogen salt in a single jet process or 
a double jet process. The localized phase can also be formed by a 
conversion method which includes a process of converting the formed silver 
halide into another silver halide having a smaller solubility product. 
Further, the localized phase can be formed by recrystallization of silver 
bromide micrograins on the surface of silver chloride grains. These 
methods are described in various publications, such as European Patent 
Provisional Publication No. 273430A2. 
In the present invention, a metal ion other than silver ion (e.g., the 
metal ions of the VIII group in periodic table, the transition metal ions 
of the II group, lead ion and thallium ion) is preferably added to the 
localized phase or the base of the phase (i.e., the portion other than the 
localized phase) in the silver halide grain to improve the effect of the 
invention. 
Iridium ion, rhodium ion or iron ion is preferably added to the localized 
phase. Osmium ion, iridium ion, rhodium ion, platinum ion, ruthenium ion, 
palladium ion, cobalt ion, nickel ion, iron ion or a complex ion thereof 
is preferably added to the base of the phase. The phase may be different 
from the base in the nature and amount of the metal ion 
The metal ion can be contained in the localized phase and/or the base in 
the silver halide grain by adding the metal ion into a silver halide 
emulsion in preparation before or after the grain formation or at the 
stage of physical ripening. For example, the metal ion can be added to a 
gelatin solution, a halogen salt solution, a silver salt solution or the 
other solutions to form silver halide grains. 
Further, the metal ion can be introduced into the silver halide grain by 
adding silver halide micrograins which contain a metal ion to a silver 
halide emulsion, and dissolving the silver halide micrograins. This method 
is advantageous to the preparation of the silver halide grain in which the 
silver bromide localized phase is arranged on the surface of the grain. 
The method of adding the metal ion can be selected depending on the 
position where the metal ion is localized. 
At least 50% of iridium ion based on the total amount of the ion contained 
in the silver halide grain is preferably deposited together with the 
localized phase. 
The iridium ion can be deposited together with the localized phase by 
adding an iridium compound either before, simultaneously with or after the 
addition of silver and/or halogen. 
The silver halide grain used in the present invention preferably has a 
hundred and/or a hundred and eleven sides on the surface. The grain may 
have sides of a higher order. 
The shape of the silver halide grain may be either in the form of a regular 
crystal (e.g., cube, tetradecahedron and octahedron) or in the form of an 
irregular crystal (e.g., globular and tabular shapes). Further, the shape 
of the grain may be complex of two or more crystals. Two or more silver 
halide grains differing in the shape can be employed. At least 50% of the 
silver halide grains preferably (more preferably at least 70%, and most 
preferably at least 90%) are in the form of a regular crystal. A tabular 
silver halide grain having an aspect ratio (length/thickness) of not less 
than 5 (more preferably not less than 8) can be also employed in an amount 
of at least 50% based on the total projected area of the silver halide 
grains. 
The silver halide grains used in the present invention have a mean grain 
size in the conventional range, and preferably in the range of 0.1 to 1.5 
.mu.m. There is no specific limitation on the grain size distribution of 
silver halide grains. Silver halide grains having an almost uniform grain 
size distribution are preferably employed. In more detail, the silver 
halide grains preferably have such a grain size distribution that the 
coefficient of variation (S/d) is not more than 20%, wherein "S" means a 
standard deviation of the grain size as a circular approximation of the 
projected area and "d" means the average grain size. The coefficient of 
the variation more preferably is not more than 15%. 
A mixture of a silver halide emulsion containing tabular silver halide 
grains and an emulsion having an almost uniform grain size distribution 
can be employed. The latter emulsion preferably has the above-defined 
coefficient of the variation. It is more preferred that the mixture also 
has the coefficient of the variation. 
The portion other than the localized phase (i.e., the base) may be either 
heterogeneous from the inside to the surface of the grain or homogeneous. 
The silver halide emulsion used in the present invention is usually 
physically and chemically ripened and spectrally sensitized. Preferred 
examples of the chemical sensitizer used for the chemical ripening are 
described at pages 18 to 22 in Japanese Patent Provisional Publication No. 
62(1987)-215272. Preferred examples of the spectral sensitizer are 
described at pages 22 to 38 in Japanese Patent Provisional Publication No. 
62(1987)-215272. 
Further, preferred examples of the antifogging agent and the stabilizer 
which are used in the preparation or preservation of the silver halide 
emulsion are described at pages 39 to 72 in Japanese Patent Provisional 
Publication No. 62(1987)-215272. 
Examples of the magenta coupler used in the present invention include oil 
protected couplers, such as indazolone couplers, cyanoacetyl couplers 
5-pyrazolone couplers and pyrazoloazole couplers. The 5.pyrazolone 
couplers and the pyrazoloazole couplers (e.g., pyrazolotriazoles) are 
preferred. The 5-pyrazolone couplers are preferably substituted with an 
arylamino group or an acylamino group at 3-position from the viewpoint of 
the hue of the developed dye and the density of the color. Examples of the 
substituted 5.pyrazolone couplers are described in U.S. Pat. No. 
2,311,082, No. 2,343,703, No. 2,600,788, No. 2,908,573, No. 3,062,653, No. 
3,152,896 and No. 3,936,015. The elimination group of two equivalent 
5-pyrazolone coupler preferably is the nitrogen eliminating group 
described in U.S. Pat. No. 4,351,987 or an arylthio group described in 
International Provisional Publication No. WO-88-04795. The 5-pyrazolone 
coupler having a ballast group described in European Patent No. 73,636 
gives a high color density. 
Preferred examples of the pyrazoloazole couplers include 
pyrazolo[5,1-c][1,2,4]triazoles described in U.S. Pat. No. 3,725,067, 
pyrazolotetrazoles described in Research Disclosure 24220 (Jun., 1984) and 
pyrazolopyrazoles described in Research Disclosure 24230 (Jun., 1984). The 
above-mentioned couplers may be in the form of a polymer coupler. 
In more detail, the magenta couplers preferably are the compounds having 
the following formula [M-I], [M-II] or [M-III].

It is preferred that the unwanted absorption of the magenta coupler within 
the yellow range is small and the formed dye is stable to light. From 
these view points, imidazo[1,2-b]pyrazoles described in U.S. Pat. No. 
4,500,630 are preferred, and pyrazolo[1,5-b][1,2,4]triazoles described in

organic solvent can be used together with the couplers. Preferred examples 
of the polymers are homopolymers and copolymers described at pages 12-30 
in International Provisional Publication No. W088/00723. Acrylamide 
polymers are particularly preferred, since they improve the stability of 
the color image.

hydroquinone derivatives, aminophenol derivatives, gallic acid derivatives 
and ascorbic acid derivatives as anticolorfogging agents. 
The photosensitive material of the invention can contain an ultraviolet

hydrophilic polymers can be used singly or in combination with gelatin. 
In the present invention, limed gelatin and acid-processed gelatin are

Vice, "The Macromolecular Chemistry of Gelatin" (Academic Press, 1964). 
As the support for the photosensitive material of the present invention, a 
transparent film, such as cellulose nitrate film and polyethylene 
terephthalate film, and a reflective support are available. The reflective 
support is preferably used in the present invention. 
In the present invention, the reflective support has a function of making 
clear a dye image formed on the silver halide emulsion layer by the 
reflection. The reflective support can be prepared by coating a base sheet 
with a hydrophobic resin which contains reflective substances, such as 
titanium dioxide, zinc oxide, calcium carbonate, calcium sulfate. The

a paper coated with polyethylene and a polypropylene synthetic paper are 
available. Examples of the base sheet to be coated with the reflective 
substances include various transparent materials, such as grass board, 
polyester film (e.g., polyethylene terephthalate film, cellulose 
triacetate film and cellulose nitrate film), polyamide film, polycarbonate 
film, polystyrene film and vinyl chloride film. The support is selected 
from the above-mentioned materials according to use of the photosensitive 
material. 
It is preferred that the reflective substances, such as white pigments are 
finely dispersed on the support by mixing the substances and hydrophobic 
resin with a surface active agent. The surface of the pigments is 
preferably treated with a di-, tri- or tetrahydric alcohol. 
The ratio of the area occupied by the white pigments (%) is determined by 
measuring the ratio (%) (R.sub.i) of the area projected from the particles 
of the white pigments to a unit area. The observed area has been divided 
by the unit area (6 .mu.m.times.6 .mu.m). The coefficient of the variation 
with respect to the ratio of the occupied area is s.sqroot.R in which "s" 
means a standard deviation of R.sub.i, and "R " means the average value of 
R.sub.i. The number of the unit areas to be measured is preferably not 
less than 6. The coefficient of the variation (s.sqroot.R) is calculated 
from the following formula. 
##EQU1## 
In the present invention, the coefficient of the variation with respect to 
the ratio of the area occupied by the pigment is preferably not more than 
0.15, and more preferably not more than 0.12. When the coefficient is not 
more than 0.08, the particles are substantially "uniformly" dispersed. 
The color photosensitive material of the present invention is preferably 
processed by color development, bleach-fix and washing (or stabilization). 
The bleach and the fix can be separately conducted. 
In continuous processing, the amount of the replenishing developing 
solution is preferably as small as possible for saving resources and 
preventing pollution. 
The replenishing amount of the color developing solution is preferably not 
more than 200 ml per 1 m.sup.2 of the photosensitive material, more 
preferably not more than 120 ml, and most preferably not more than 100 ml. 
The above-defined replenishing amount only relates to the amount of the 
replenishing color developing solution, and does not include the additives 
which adjust the developing solution to change of the quality and 
concentration of the solution. Examples of the additives include water 
which dilutes the condensed solution, preservatives which tend to be 
degraded, and alkali which keeps the pH value high. 
The color developing solution used in the present invention preferably is 
an alkaline solution which mainly contains an aromatic primary amine color 
developing agent. Aminophenols and p-phenylenediamines are available as 
the color developing agent. P-phenylenediamines are particularly 
preferred. Examples of the developing agent include 
3-methyl-4-amino-N,N-diethylaniline, 
3-methyl-4-amino-N-ethyl-N-.beta.-hydroxyethylaniline, 
3-methyl-4-amino-N-ethyl-N-.beta.-methanesulfonamidoethylaniline and 
3-ethyl-4-amino-N-ethyl-N-.beta.-methoxyethylaniline. Sulfate, 
hydrochloride and p-toluenesulfonate of these compounds are also 
available. Two or more compounds can be used in combination. 
The color developing solution generally contains a pH buffer (e.g., 
carbonate, borate or phosphate of alkali metal) and a development 
inhibitor or an antifogging agent (e.g., bromide salts, iodide salts, 
benzimidazoles, benzothiazoles and mercapto compounds). The developing 
solution can further contain various preservatives (e.g., hydroxyamines, 
diethylhydroxyamines, hydrazines sulfites, phenylsemicarbazides, 
triethanolamine, catechol sulfates, triethylenediamine and 
1,4-diazabicyclo[2,2,2]octane); organic solvents (e.g., ethylene glycol 
and diethylene glycol); development accelerators (e.g., benzyl alcohol, 
polyethylene glycol and tertially ammonium salts); fogging agents (e.g., 
dye-forming couplers, competitive couplers and sodium boron hydride); 
complementary developing agents (e.g., 1-phenyl-3-pyrazolidone); viscosity 
agents; and chelating agent such as aminopolycarboxylic acids, 
aminopolyphosphonic acid and phosphorylcarboxylic acids (e.g, 
ethylenediaminetetraacetic acid, nitrilotriacetic acid, 
diethylenetriaminepentaacetic acid, cyclohexanediaminetetraacetic acid, 
hydroxyethyimidinoacetic acid, 1-hydroxyethylidene-1,1-diphosphonic acid, 
nitrilo-N,N,N-trimethylenephosphonic acid, 
ethylenediamine-di(o-hydroxyphenyl)acetic acid and the salts thereof). 
In a reversal development, a black and white development is usually 
followed by a color development. The developing solution for the black and 
white development contains the known black and white developing agents, 
such as dihydroxybenzenes (e.g., hydroquinone), 3-pyrazolidones (e.g., 
1-phenyl-3-pyrazolidone) and aminophenols (e.g., N-methyl-p-aminophenol). 
These agents can be used in combination. 
The pH value of the color developing solution or the black and white 
developing solution is generally in the range of 9 to 12. The replenishing 
amount of the developing solution is usually not more than 3 l per 1 
m.sup.2 of the color photosensitive material. The replenishing amount can 
be reduced to not more than 500 ml by reducing the concentration of 
bromide ion in the replenishing solution. When the replenishing amount is 
reduced, it is preferred to prevent the solution from the evaporation or 
the air oxidation by minimize the contact surface of the solution to the 
air. Further, a means of restraining accumulation of bromide ion in the 
developing solution can be employed to reduce the replenishing amount. 
After the color development, the photographic emulsion layer is usually 
bleached. The bleach can be conducted together with the fix (bleach-fix 
process). The bleach and the fix can be separately conducted. Further, the 
bleach process can be followed by the bleach-fix process for rapid 
development. Furthermore, a continuous processing using two bleaching 
baths, a fix process followed by a bleach-fix process and a bleach-fix 
process followed by a bleach process can be employed. As the bleaching 
agent, compounds of polyvalent metals such as iron (III), cobalt (III), 
chromium (VI), copper (II), peracids, quinones and nitro compounds are 
available. Examples of the bleaching agent include ferricyanides; 
bichromates: organic complexes of iron (III) or cobalt (III), such as 
complexes of aminopolycarboxylic acids (e.g., ethylenediaminetetraacetic 
acid, diethylene triaminepentaacetic acid, cyclohexanediaminetetraacetic 
acid, methyliminodiacetic acid, diaminopropanetetraacetic acid, 
glycoletherdiaminetetraacetic acid), citric acid, tartaric acid and malic 
acid; persulfates; bromates; permanganates; and nitrobenzenes. Iron (III) 
complexes of aminopolycarboxylic acids (e.g., iron (III) complex of 
ethylenediaminetatraacetic acid) and persulfates are preferred, since 
these compounds are advantageous to the rapid processing and the 
prevention of pollution. Iron (III) complexes of aminopolycarboxylic acids 
are available in both of bleaching bath and bleach-fix bath. The pH value 
in the bleaching or bleach-fix bath using the iron (III) complexes of 
aminopolycarboxylic acids is usually in the range of 5.5 to 8. The pH 
value can be further lowered for the rapid processing. 
A bleaching accelerator can be used in the bleaching bath, the bleach-fix 
bath or the prebath thereof. Examples of the bleaching accelerator include 
compounds having a mercapto group or a disulfide group (cf., U.S. Pat. No. 
3,893,858, German Patents No. 1,290,812 and No. 2,059,988, Japanese Patent 
Provisional Publications No. 53(1978)-32736, No. 53(1978)-57831, No.

3,706,561); iodides (cf., German Patent No. 1,127,715, and Japanese Patent 
Provisional Publication No. 58(1983)-16235); polyoxyethylene compounds 
(cf., German Patents No. 996,410 and No. 2,748,430); polyamines (cf., 
Japanese Patent Publication No. 45(1970)-8836); the other compounds 
described in Japanese Patent Provisional Publications No. 49(1974)-42434, 
No. 49(1974)-59644, No. 53(1978)-94927, No. 54(1979)-35727, No. 
55(1980)-26506 and No. 58(1983)-163940; and bromide ion. The compounds 
having a mercapto group or a disulfide group are preferred, since they 
have a strong effect. The compounds described in U.S. Pat. No. 3,893,858, 
German Patent No. 1,290,812 and Japanese Patent Provisional Publication 
No. 53(1978)-95630 are particularly preferred. The compounds described in 
U.S. Pat. No. 4,552,834 are also preferred. The above-mentioned bleaching 
accelerator can be added to the photosensitive material. The bleaching 
accelerator is particularly effective in the bleach-fix process of a color 
photosensitive material. 
Examples of the fixing agent include thiosulfates, thiocyanates, 
thioethers, thioureas and iodide salts which are used in a relatively 
large amount. Thiosulfates are usually used. Sodium thiosulfate is 
particularly available in various fields. Examples of the preservatives 
for the bleach-fix solution include sulfite salts, bisulfite salts and 
carbonyl adducts of bisulfite. 
In the process of the silver halide color photosensitive material of the 
present invention, a washing process and/or stabilization process is 
conducted after a desilvering process. The amount of water in the washing 
process is determined according to the nature of the photosensitive 
material (e.g., the nature of the components such as coupler), use of the 
material, temperature of washing water, the number of washing tanks 
(washing stages), the replenishing method (countercurrent or not), and the 
other conditions.The relation between the number of washing tanks and the 
amount of water in a multistage countercurrent method is described in 
Journal of the Society of Motion Picture and Television Engineers, vol. 
64, p. 248-253 (May, 1955). 
According to the multistage countercurrent method described in the 
above-mentioned document, the amount of washing water can be greatly 
reduced. However, this method has a disadvantage of increasing the 
stagnant time of water in a tank. This disadvantage further causes a 
problem that the propagation of bacteria causes a suspended matter, which 
is attached to the photosensitive material. In order to solve the problem, 
the method of reducing the amount of calcium ion and magnesium ion 
described in Japanese Patent Application No. 61(1986)-131632 is effective. 
Further, isothiazolone compounds and cyabendazoles described in Japanese 
Patent Provisional Publication No. 57(1982)-8542, chlorine germicides such 
as chlorinated sodium isocyanurate, and benzotriazole are available as 
germicide. 
The pH value of washing water in the process of the photosensitive material 
of the invention preferably is in the range of 4 to 9, and more preferably 
in the range of 5 to 9. The temperature of washing water and the washing 
time are determined according to the nature and use of the photosensitive 
material. The washing process is usually conducted at 15.degree. to 45 
.degree. C. for 20 seconds to 10 minutes, and more preferably at 
25.degree. to 40 .degree. C. for 30 seconds to 5 minutes. The 
photosensitive material of the invention can be directly processed by a 
stabilizer in place of the above-mentioned washing process. The 
stabilization process can be conducted by the known methods which are 
described in Japanese Patent Provisional Publications No. 57(1982)-8543, 
No. 58(1983)-14834 and No. 60(1985)-220345. 
The stabilization process can follow the washing process. A example of such 
process is the last bath of a color photosensitive material, which is a 
stabilization bath containing formaldehyde and a surface active agent. The 
stabilization bath can further contain various chelating agents and 
germicides. 
The overflow solution caused by replenishing the washing and/or 
stabilization solution can be recycled in the other process such as a 
desilvering process. 
The silver halide color photosensitive material of the present invention 
can contain a color developing agent for simple and rapid processing. The 
color developing agent is preferably in the form of a precursor to be 
contained in the photosensitive material. Examples of the precursor of the 
agent include indoaniline compounds (cf., U.S. Pat. No. 3,342,597), Schiff 
base compounds (cf., U.S. Pat. No. 3,342,599, and Research Disclosures No. 
14,850 and No. 15,159), aldole compounds (cf., Research Disclosure No. 
13,924), metal salt complexes (cf., U.S. Pat. No. 3,719,492) and urethane 
compounds (cf., Japanese Patent Provisional Publication No. 
53(1978)-135628). 
The silver halide color photosensitive material of the invention can 
contain various 1-phenyl-3-pyrazolidones to accelerate the color 
development. Examples of the compounds are described in Japanese Patent 
Provisional Publications No. 56(1981)-64339, No. 57(1982)-144547 and No. 
58(1983)-115438. 
In the present invention, the various processing solutions are used at 
10.degree. to 50 .degree. C., and usually at 33.degree. to 38 .degree. C. 
A higher temperature can be employed to accelerate the process or to 
shortening the processing time. A lower temperature can also be employed 
to improve the quality of the image or the stability of the processing 
solution. To save the amount of silver contained in the photosensitive 
material, an intensification process using cobalt or hydrogen peroxide is 
available. The intensification process is described in German Patent No. 
2,226,770 and U.S. Pat. No. 3,674,499. 
In order to exhibit the excellent character of the silver halide 
photosensitive material, the material is preferably processed for not more 
than 2 minutes and 30 seconds using a color developing solution which 
substantially es not contain benzyl alcohol and contains bromide ion in an 
amount of not more than 0.002 mole/1. 
The term "not contain benzyl alcohol" means the amount of not more than 2 
ml per 1 l of the color developing solution. The amount is preferably not 
more than 0.5 ml. It is most preferred that the developing solution 
completely does not contain benzyl alcohol. 
The present invention is further described by the following examples 
without limiting the invention.

A paper was laminated with polyethylene on the both side to prepare a paper 
support. On the paper support, the following coating solution were coated 
to prepare a multi-layered color photosensitive material. 
Preparation of Coating Solution for the First Layer 
In 27.2 ml of methyl acetate, 3.8 ml of a solvent (Solv-1) and 3.8 ml of a 
solvent (Solv-2) were dissolved 19.1 g of a yellow coupler (Y-45) and 0.46 
g of an antifogging agent (Cpd-2). The solution was emulsified in 185 ml 
of 10% aqueous gelatin solution containing 8 ml of 10% solution of sodium 
dodecylbenzenesulfonate. Separately, to the mixture of the silver halide 
emulsions (1) and (2) (the ratio of (1) to (2) is 6:4) was added the 
following blue sensitive spectral sensitizing dye in the amount of 
5.0.times.10.sup.-4 mole per the 1 mole of silver. The previously prepared 
emulsion is mixed with the mixture of the silver halide emulsions to 
prepare a coating solution for the first layer. 
The coating solutions for the second to seventh layers were prepared in a 
similar manner. 
As the hardening agent for the layers, sodium salt of 
1-oxy-3,5-dichloro-s-triazine (hardening agent for gelatin) was used. 
The following spectral sensitizing dyes were used for the layers. 
##STR53## 
To the red sensitive emulsion layer was added 2.6.times.10.sup.-3 mole (per 
1 mole of silver halide) of the following compound. 
##STR54## 
To the blue sensitive emulsion layer was added 1.2.times.10.sup.-2 mole 
(per 1 mole of silver halide) of 
4-hydroxy-6-methyl-1,3,3a,7-tetraazaindene. Further, to the green 
sensitive emulsion layer was added 1.1.times.10.sup.-2 mole of 
4-hydroxy-6-methyl-1,3,3a,7-tetraazaindene. 
To the green sensitive emulsion layer was added 1.0.times.10.sup.-3 mole 
(per 1 mole of silver halide) of 
1-(5-methylureidophanyl)-5-mercaptotetrazole. 
To the red sensitive emulsion layer was added 3.0.times.10.sup.-4 mole (per 
1 mole of silver halide) of 2-amino-5-mercapto-1,3,4-thiadiazole. 
As the antiirradiation dye, the following compounds were used.

Thus, a sample 1A was obtained. The other samples were prepared in the same 
manner except that the yellow coupler and an additive (color stabilizer) 
[50 mole % based on the amount of the coupler] contained in the first 
layer were changed according to the following Table 1. 
Each of the samples, on which an image had been formed, was irradiated with 
light for 8 days in a xenon tester at 200,000 lux. The density of the 
image was measured, and the remaining ratio to the density of the image 
(1.0) before the irradiation was obtained. 
The stability to heat was measured by placing the samples at 100 .degree. 
C. for 400 hours. The remaining ratio to the density of the image (1.0) 
before heating was obtained. 
The results are set forth in Table 1. The density was measured using 
Macbeth's densitometer RD.514 (Status, AA filter). In Table 1, the 
"Remaining Ratio to Light" shows the results of the remaining ratio after 
irradiation, and the "Remaining Ratio to Light" shows the results of the

Deionized water was used throughout for the processes. Water was deionized 
to contain calcium and magnesium ions in an amount of not more than 3 ppm 
(the conductivity at 25 .degree. C. was 5 .mu.s/cm). 
Thus, a sample 2A was obtained. The other samples were prepared in the same 
manner except that the yellow coupler and an additive (color stabilizer) 
[50 mole % based on the amount of the coupler] contained in the first 
layer were changed according to the following Table 2. 
Each of the samples, on which an image had been formed, was irradiated with 
light for 4 weeks in a fluorescent lamp fading tester at 15,000 lux. The 
density of the image was measured, and the remaining ratio to the density 
of the image (1.0) before the irradiation was obtained. 
Further, the maximum reflection density (Dmax) with respect to the yellow 
image was measured. The relative values to the sample 2A containing no 
stabilizer (100) were obtained. 
The results are set forth in Table 2. In the Table 2, the "Remaining Ratio"

inhibiting the color formation of the coupler, compared with the 
comparison compounds. 
EXAMPLE 6 
The experiments with respect to the samples 5A, 5B, 5C, 5D, 5E, 5L, 5M, 50 
and 5R were repeated except that the yellow couplers were changed to Y-10, 
Y-46, Y-47, Y-35 and Y-62 respectively. As the results, it is also 
apparent that the compounds of the present invention is much effective in 
preventing the color image from fading. 
EFFECT OF THE INVENTION 
The silver halide color photosensitive material of the present invention is 
characterized in that the layer containing a yellow coupler further 
contains a compound having the formula [I] or [II]. The photosensitive 
material of the invention is much improved in the stability of the 
photographic image. 
The silver halide color photosensitive material of the present invention 
does not affect the color formation of a yellow coupler, and gives a 
yellow dye image which is stable to light, heat and humidity.
