Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 86 words
A color photographic material having a light-sensitive silver halide emulsion layer coated on a support, which comprises (1) a DIR compound which releases a diffusive development-inhibiting substance, said substance having an amino group, by a coupling reaction with an oxidation product of an aromatic primary amine developing agent (DIR compound (I)) and (2) a DIR compound which releases a diffusive development-inhibiting substance, said substance having no amino group, by a coupling reaction with an oxidation product of an aromatic primary amine developing agent (DIR compound (II)).
Claim 2
Dependent Claim 86 words
A color photographic material having a light-sensitive silver halide emulsion layer coated on a support, which comprises (1) a DIR compound which releases a diffusive development-inhibiting substance, said substance having an amino group, by a coupling reaction with an oxidation product of an aromatic primary amine developing agent (DIR compound (I)) and (2) a DIR compound which releases a diffusive development-inhibiting substance, said substance having no amino group, by a coupling reaction with an oxidation product of an aromatic primary amine developing agent (DIR compound (II)).
Claim 3
Dependent Claim 121 words
A color photographic material according to claim 1 wherein the DIR compound (I) and DIR compound (II) are those described by the formula (I) and (II) respectively: C.sub.p -Z.sub.1 (I) C.sub.p -Z.sub.2 (II), wherein the formulae C p is a coupler residue, being capable of coupling with an oxidation product of an aromatic primary amine developing agent, Z 1 is a residue which is released to be a diffusive development-inhibiting substance having an amino group, by coupling reaction with the oxidation product of the aromatic primary amine developing agent, Z 2 is a residue which is released to be a diffusive development-inhibiting substance having no amino group, by coupling reaction with the oxidation product of the aromatic primary amine developing agent.
Claim 4
Dependent Claim 121 words
A color photographic material according to claim 2 wherein Z 1 is represented by ##STR4## and Z 2 is represented by ##STR5## wherein X 1 is a 5 or 6 membered heterocycle containing a nitrogen, oxygen or sulfur, and having no amino group other than that described in the formula (III), X 1 ' is a 5 or 6 membered heterocycle containing a nitrogen, oxygen or sulfur and having no amino group, X 2 is a 5 membered heterocycle containing two nitrogen atoms and having no amino group other than that described in the formula (IV), X 2 ' is a 5 membered heterocycle containing two nitrogen atoms and having no amino group, and R is hydrogen, alkyl, aryl or heterocycle.
Claim 5
Dependent Claim 12 words
A color photographic material according to claim 3 wherein R is hydrogen.
Claim 6
Dependent Claim 28 words
A color photographic material according to claim 3 wherein Z 1 is represented by ##STR6## wherein X 1 and R have same meanings as defined in claim 3.
Claim 7
Dependent Claim 32 words
A color photographic material according to claim 3 wherein Z 1 and Z 2 are represented by ##STR7## respectively, wherein X 1 and R have same meanings as defined in claim 3.
