Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 269 words
A silver halide color photographic light-sensitive material comprising a reflective support bearing thereon a green light-sensitive silver halide emulsion layer containing a magenta forming coupler represented by the following Formula (I); a blue light-sensitive silver halide emulsion layer containing a yellow-forming coupler represented by the following Formula (II); and a red light-sensitive silver halide emulsion layer containing a cyan-forming coupler represented by the following Formula (III) or (IV); ##STR21## wherein R 1 represents a tertiary alkyl group; R 2 represents an alkyl group or an aryl group; and X represents a split-off group other than hydrogen, which is capable of splitting off through a reaction with the oxidation products of a color developing agent; ##STR22## wherein X 1 represents a halogen, an alkoxy group or an alkyl group; Y 1 represents a group capable of splitting off when a dye is formed by coupling the group with the oxidation products of an aromatic primary amine color developing agent; R 4 represents a group substitutable to a benzene ring; and n is an integer of 1 or 2; ##STR23## wherein R 5 represents an alkyl group having 1 to 4 carbon atoms; R 6 represents hydrogen or an alkyl group having 1 to 15 carbon atoms; and R 7 represents a halogen, an alkyl group, a hydroxy group or an acyloxy group; ##STR24## wherein R 8 represents an alkyl group, a halogen, a sulfonamido group, a sulfamoyl group, an arylsulfonyl group, or a hydroxy group; R 9 represents hydrogen or an alkyl group; and R 10 represents hydrogen, a halogen, an alkyl group, a sulfamoyl group or a sulfonamido group.
Claim 2
Dependent Claim 269 words
A silver halide color photographic light-sensitive material comprising a reflective support bearing thereon a green light-sensitive silver halide emulsion layer containing a magenta forming coupler represented by the following Formula (I); a blue light-sensitive silver halide emulsion layer containing a yellow-forming coupler represented by the following Formula (II); and a red light-sensitive silver halide emulsion layer containing a cyan-forming coupler represented by the following Formula (III) or (IV); ##STR21## wherein R 1 represents a tertiary alkyl group; R 2 represents an alkyl group or an aryl group; and X represents a split-off group other than hydrogen, which is capable of splitting off through a reaction with the oxidation products of a color developing agent; ##STR22## wherein X 1 represents a halogen, an alkoxy group or an alkyl group; Y 1 represents a group capable of splitting off when a dye is formed by coupling the group with the oxidation products of an aromatic primary amine color developing agent; R 4 represents a group substitutable to a benzene ring; and n is an integer of 1 or 2; ##STR23## wherein R 5 represents an alkyl group having 1 to 4 carbon atoms; R 6 represents hydrogen or an alkyl group having 1 to 15 carbon atoms; and R 7 represents a halogen, an alkyl group, a hydroxy group or an acyloxy group; ##STR24## wherein R 8 represents an alkyl group, a halogen, a sulfonamido group, a sulfamoyl group, an arylsulfonyl group, or a hydroxy group; R 9 represents hydrogen or an alkyl group; and R 10 represents hydrogen, a halogen, an alkyl group, a sulfamoyl group or a sulfonamido group.
Claim 3
Dependent Claim 23 words
The silver halide color photographic light-sensitive material as claimed in claim 1, wherein X denoted in the Formula (I) represents a halogen atom.
Claim 4
Dependent Claim 30 words
