Abstract
Abstract A method for forming a silver halide color photographic image comprising forming a dye image in the presence of a phenol cyan coupler. The phenol cyan coupler has the following formula: ##STR1## wherein R is an alkyl, an aryl or a heterocyclic group; X is selected from the group consisting of an alkyl, acyloxy, acylamino, succinimide, and sulfoneamide moiety; Z is a hydrogen atom or a group capable of eliminating itself from the coupler during the coupling reaction with the oxidized product of a color developing agent; and n is an integer from 1 to 3, and when n is 2 or 3, X may be the same or different.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
115 words
A method for forming a silver halide color photographic image comprising the step of forming a dye image in the presence of a phenol cyan coupler, said phenol cyan coupler having the formula: ##STR7## wherein R is an alkyl, an aryl or a heterocyclic group; X is selected from the group consisting of an alkyl, acyloxy, acylamino, succinimide, piprolidine, piperidine and sulfoneamide moiety; Z is a hydrogen atom or a group capable of eliminating itself from said coupler during the coupling reaction thereof with the oxidized product of a color developing agent; and n is an integer from 1 to 3, wherein when n is 2 or 3, X may be the same or different.
Claim 2
Independent Claim
115 words
A method for forming a silver halide color photographic image comprising the step of forming a dye image in the presence of a phenol cyan coupler, said phenol cyan coupler having the formula: ##STR7## wherein R is an alkyl, an aryl or a heterocyclic group; X is selected from the group consisting of an alkyl, acyloxy, acylamino, succinimide, piprolidine, piperidine and sulfoneamide moiety; Z is a hydrogen atom or a group capable of eliminating itself from said coupler during the coupling reaction thereof with the oxidized product of a color developing agent; and n is an integer from 1 to 3, wherein when n is 2 or 3, X may be the same or different.
