Abstract
Abstract The invention relates to multi-layered color photosensitive materials having a support, a red photosensitive silver halide emulsion layer containing a non-diffusible cyan coupler, a green photosensitive silver halide emulsion layer containing a non-diffusible yellow coupler and a blue photosensitive silver halide emulsion layer containing a non-diffusible magenta coupler coated on a support in the order recited and wherein the green photosensitive emulsion layer contains a compound capable of reacting with an oxidized color developing agent to release a development inhibiting substance.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
75 words
A multi-layered color photosensitive material comprising a support, and a red-photosensitive silver halide emulsion layer containing a nondiffusion cyan coupler, a green-photosensitive silver halide emulsion layer containing nondiffusion yellow coupler and a blue-photosensitive silver halide emulsion layer containing a nondiffusion magenta coupler provided in this order on the support, said green-photosensitive silver halide emulsion layer comprising a compound which is capable of releasing a development inhibiting substance by reacting with an oxidized color developing agent.
Claim 2
Dependent Claim
75 words
A multi-layered color photosensitive material comprising a support, and a red-photosensitive silver halide emulsion layer containing a nondiffusion cyan coupler, a green-photosensitive silver halide emulsion layer containing nondiffusion yellow coupler and a blue-photosensitive silver halide emulsion layer containing a nondiffusion magenta coupler provided in this order on the support, said green-photosensitive silver halide emulsion layer comprising a compound which is capable of releasing a development inhibiting substance by reacting with an oxidized color developing agent.
Claim 3
Dependent Claim
72 words
A multi-layered color photosensitive material according to claim 1, the compound is represented by the following general formula (1): A - TIME - Z (1) wherein A represents an ingredient which is, upon reaction with an oxidized color developing agent, capable of releasing TIME-Z radical therefrom, Z represents a development inhibiting ingredient, and TIME represent a timing radical which is capable of releasing Z subsequent to releasing of TIME-Z radical from A.
Claim 4
Dependent Claim
84 words
A multi-layered color photosensitive material according to claim 2, the compound is represented by the following general formula (2): ##STR9## wherein A represents an ingredient being capable of reacting with an oxidized color developing agent, X represents a substituted or unsubstituted benzene ring or a substituted or unsubstituted naphthalene ring, R 3 and R 4 independintly represent hydrogen atom, an alkyl radical or an aryl radical provided that the radical ##STR10## is substituted at orthoposition or para-position with respect to oxygen atom of formula.
Claim 5
Dependent Claim
106 words
A multi-layered color photosensitive material according to claim 2, the compound is represented by the following general formula (6): ##STR11## wherein A represents an ingredient being capable of reacting with an oxidized color developing agent, Nu represents oxygen, sulfur or nitrogen atom, G represents a radical capable of stracturally connecting Nu with E, E represents an electrophilic radical comprising carbonyl radical, thiocarbonyl radical, phosphinyl radical or thiophosphinyl radical, and Z represents a development inhibiting ingredient, provided that said -Nu-G-E-Z radical is one capable of causing, subsequent to release from A, intramolecular nucleophilic substitution reaction to form a 3 to 7 membered ring, thereby releasing Z therefrom.
Claim 6
Dependent Claim
67 words
A multi-layered color photosensitive material according to claim 3 or 4, wherein Z is represented by the following general formulas (a) to (f): ##STR12## wherein R 1 represents hydrogen atom, an alkyl radical having one to eight carbon atoms, phenyl radical or a substituted phenyl radical and R 2 represents hydrogen or halogen atom, a lower alkyl radical having one to four carbon atoms or nitro radical.
Claim 7
Dependent Claim
44 words
A multi-layered color photosensitive material according to claim 1, the chemical compound is represented by the following general formula (7): A--Z (7) wherein A represents an ingredient being capable of reacting with an oxidized color developing agent and Z represents a development inhibiting ingredient.
