Abstract
Pyrrolotriazole compounds of the formula (I) and silver halide color photographic light-sensitive materials containing the compound as a cyan coupler, are disclosed: wherein R1 and R2 each independently are an alkyl, cycloalkyl, alkenyl, aryl or heterocyclic group, or R1 and R2 may bond together to form a 5- or 6-membered nitrogen-containing heterocycle; R3 is an alkyl, cycloalkyl or alkenyl group; R5 is an alkyl or aryl group; R4, R6, R7 and R8 each independently are a hydrogen atom or a substituent, with the proviso that at least one of R4, R6, R7 and R8 is a substituent, and that two groups of R4 to R8, which adjoin each other, do not bond together to form any ring.
Claims7
A silver halide color photographic light-sensitive material containing a cyan coupler represented by the following formula (I):
- wherein R1 and R2 each independently represent an alkyl group, a cycloalkyl group, an alkenyl group, an aryl group or a heterocyclic group, or R1 and R2 may bond together to form a 5- or 6-membered nitrogen-containing heterocycle;
- R3 represents an alkyl group, a cycloalkyl group or an alkenyl group;
- R5 represents an alkyl group or an aryl group;
- and R4, R6, R7 and R8 each independently represent a hydrogen atom or a substituent, with the proviso that at least one of R4, R6, R7 and R8 represents a substituent, and that two groups of R4, R5, R6, R7 and R8, which adjoin each other, do not bond together to form any ring.
