Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
144 words
A silver halide color photographic light-sensitive material comprising a support provided thereon a hydrophilic colloidal layer containing at least one kind of phenol cyan coupler having the Formula [I] in which an ureido radical is 2-position and being dispersed by making use of a phthalic ester having the Formula [II]: ##STR6## wherein R 1 represents a straight or branched alkyl, cycloalkyl radical, R 2 represents a hydrogen atom, a halogen atom or a monovalent organic radical, R 3 represents a straight or branched alkyl radical, R 4 and R 5 each represents a branched alkyl radical, Z represents a hydrogen atom or a radical capable of eliminating in a coupling reaction with an oxidation product of a color developing agent, n represents an integer of 0 to 3; ##STR7## wherein R 6 and R 7 each represent an alkyl, alkenyl, aryl or cycloalkyl radical.
