摘要:
A silver halide color photographic light-sensitive material comprising at least one yellow color developable light-sensitive silver halide emulsion layer, at least one magenta color developable light-sensitive silver halide emulsion layer, and at least one cyan color developable light-sensitive silver halide emulsion layer, each of which is provided on a support: which comprises at least one yellow coupler of formula (I) and at least one cyan coupler of formula (A); wherein Q represents a group of non-metal atoms that form a 5- to 7-membered ring in combination with —N═C—N(R1)-, each of R1 and R2 represents a substituent, m represents an integer of 0 to 5, and X represents a hydrogen atom or a group capable of being split-off upon a coupling reaction; wherein R11 and R12 each represent an alkyl group or an aryl group, J represents an alkylene group, and X represents a hydrogen atom or a group that can split off upon a coupling reaction.
