Complete Specification for the invention entitled: PROCESS OF PROCESSING SILVER HALIDE COLOR PHOTOGRAPHIC MATERIAL The following statement is a full description of this invention, including the best method of performing it known to me/us:- 6258A:rk ft- 1 4 PROCESS OF PROCESSING SILVER HALIDE COLOR PHOTOGRAPHIC MATERIAL FIELD OF THE INVENTION This invention relates to a process of processing silver halide color photographic materials, and more particularly to a processing process for color photographic materials, wherein the stability and the coloring property of a color developer are improved and the increase of the formation of stains in continuous o ood processing is greatly reduced.
o oo 0 BACKGROUND OF THE INVENTION o o0 ooc A color developer containing an aromatic primary O o 0 0 0amine color developing agent has hitherto been mainly o 0 00 used for the formation of color images but the aforesaid color developer is very liable to be oxidized by air or 0 oo metal and it sometimes happens that the oxidation product thereof causes coupling with couplers in color 0,00 o e photographic materials to form dyes or attaches to color photographic materials to cause undesirable stains.
o t ao It is well-known to add various kinds of 0000 o antioxidants (preservatives) to color developers for 00 preventing the occurrence of the oxidation of the color developing agent. However, hydroxylamines which are well-known preservatives and used for various kinds of color developers have such disadvantages that they 4 1* Irreduce the coloring property of couplers and are liable to be decomposed by iron ions or copper ions to form the decomposition products thereof, which are liable to cause fog and give bad influences on the r otographic properties. Thus, these preservatives are not always preferable.
Also sulfite ions are well-known as preservatives and have a function of preventing the formation of fog by decomposing dyes and causing reaction with the oxidation product of a color developing agent but have disadvantages of reducing the coloring property of 00 0o couplers by acting as competing compounds to couplers and causing the reduction of color density by acting as r o V a solvent for silver halide. Thus, sulfite ions are also not preferred preservatives.
For improving the stability of color developers, 0 various investigations of various preservatives and chelating agents have been made. For example, as preservatives, there are proposed aromatic polyhydroxy compounds described in JP-A-52-49828, JP-A-59-160142, o°and JP-A-56-47038 (the term "JP-A" as used herein means an "unexamined published Japanese patent application"), and U.S. Patent 3,746,544, hydroxycarbonyl compounds described in U.S. Patent 3,615,503 and British Patent 1,306,176, c-aminocarbonyl compounds described in JP-A- -2- 1 A I 52-143020 and JP-A-53-89425, alkanolamines described in JP-A-54-3532, and metal salts described in JP-A-57-44148 and JP-A-57-53749. Also, as chelating agents, there are proposed aminopolycarboxylic acids described in JP-B-48- 30496 and JP-B-44-30232 (the term "JP-B" as used herein means an "examined published Japanese patent application"), organic phosphonic acids described in JP-A-56- 97347, JP-B-56-39359,and West German Patent 2,225,639, phosphonocarboxylic acids described in JP-A-52-102726, JP-A-53-42730, JP-A-54-121127, JP-A-55-126241 and JP-Aooo 55-65956, and the compounds described in JP-A-58-195845 So o and JP-A-58-203440, and JP-B-53-40900.
oO However, by the use of these compounds, o sufficient preservativity is not obtained and also the prevention of the occurrence of stains at continuous S'processing or after processing and the improvement of the stability of processing solutions, which are the objects of this invention, have not been sufficiently obtained.
o00o Also, in processing of silver halide color photographic materials, shortening of the processing steps and processing time is becoming a very important technical theme since it greatly contributes to the promotion of mini processing laboratories for color photographic materials or shortening of the time for -3- .1 1 1 delivery of finished products as well as the reduction of the size of an automatic processor.
For silver halide color photographic materials, various kinds of dyes are used for the purposes of preventing irradiation at image exposure or at printing, or increasing the stability to so-called safelight without reducing the sensitivity, reducing the latent image sterage stability, giving bad influences on the photographic properties, and reducing the quality of o images by causing stains (color residue) after processing.
However, when in quick processing, washing is Sinsufficient or these dyes are dissolved 'in a color developer, wash water, and/or a stabilization solution, the processing solutions are colored or even the processed color photographic materials are colored to form undesirable stains as the case may be. These oo o o phenomena are serious problems in, particularly, quick processing.
otoo, For preventing the occurrence of stains (stains at background portions) caused by such dyes, it is preferred to use dyes which become colorless dyes by being decomposed by alkali or reducing agent in a color developer but it frequently happens that the decomposition is insufficient to cause undesirable color -4 stains and thus sufficiently satisfactory techniques of overcoming the aforesaid problems have not yet been found.
SUMMARY OF THE INVENTION A first object of this invention is, therefore, to provide a process of processing silver halide color photographic materials excellent in the stability of the color developer being used.
A second object of this invention is to provide Sa process of processing silver halide color photographic materials giving greatly reduced formation of stains at o° continuous processing.
o~o o A third object of this invention is to provide a process of processing silver halide color photographic materials giving less stains after processing the color photographic materials even in quick processing.
S0 It has now been discovered that the aforesaid ooo o0 objects can be effectively attained by the process of this invention as described herein below.

1 03 The cyan couplers shown by formula can be synthesized based on the descriptions in JP-A-59-166956 and JP-B-49-lJ.572.
In this invention, the graininess of the color images formed can be improved by using a coupler giving colored dye havIng a proper diffusibility together with the aforesaid couplers(s). About such couplers giving 106 diffusible dyes, specific examples of the magenta couplers are described in U.S. Patent 4,366,237 and British Patent 2,125,570 and specific examples of the yellow, magenta and cyan couplers are described in European Patent 96,570 and West German Patent Application (OLS) No. 3,234,533.
The dye-forming couplers and the specific couplers described above may form a dimer or polymer.
Typical examples of the polymerized dye-forming couplers o are described in U.S. Patents 3,451,820 and 4,080,211.
Also, specific examples of the polymerized magenta couplers are described in British Patent 2,102,173 and U.S. Patent 4,367,282.
The couplers for use in this invention can be used for one light-sensitive emulsion layer as a mixture of two or more for meeting the properties required for the color photographic material or the same kind of o 0' coupler may be incorporated in two or more photographic layers.
So The coupler for use in this invention can be o introduced into silver halide emulsions by an oil dropin-water dispersion method. Examples of a high-boiling organic solvent being used for the oil drop-in-water dispersion method are described in U.S. Patent 2,322,027. Also, the coupler can be introduced into the 107 silver halide emulsions by a latex dispersion method and specific examples of the step and the effect of the latex dispersion method and the latex for the impregnation are described in U.S. Patent 4,199,363 and West German Patent Application (OLS) Nos. 2,341,274 and 2,541,230.
A standard amount of the color coupler is in the range of from 0.001 mol to 1 mol per mol of the lightsensitive silver halide in the silver halide emulsion, with from 0.01 mol to 0.5 mol of a yellow coupler, from o 0.003 mol to 0.3 mol of a magenta coupler, and from 0.002 mol to 0.3 mol of a cyan coupler, per mol of the light-sensitive silver halide being preferred.
The color photographic materials being processed by the process of this invention is prepared by coating eo i S the aforesaid emulsions, etc., on a flexible support 0 00 such as plastic films (films of cellulose nitrate, o cellulose acetate, polyethylene terephthalate, etc.), papers, etc., or a solid support such as glass plates, etc.
SDetailed of such supports and. the coating methods are described in Research Disclosure, Vol. 176, No. 17643, XV (page 27) and XVII (page 28) (December, 1978).
108 L The process of this invention is preferably applied to color photographic materials using reflective supports. The "reflective support" is a support having high reflectivity for clearly viewing color images forming in silver halide emulsion layer(s) and includes a support coated with a hydrophobic resin having dispersed therein a light reflective material such as titanium oxide, zinc oxide, calcium carbonate, calcium sulfate, etc., and a support composed of a hydrophobic 2 resin containing the light reflective material described above.
The inven:tion is now illustrated in detail with reference to the following examples but the invention is not limited thereto.
