ABSTRACT:
A silver halide color photographic light-sensitive material comprising a support having provided thereon at least one silver halide emulsion layer, wherein the silver halide color photographic material contains at least one cyan coupler represented by the general formula (I) described below and at least one cyan coupler represented by the general formula (II) described below ##STR1## wherein R.sub.1 represents an alkyl group having at least 8 carbon atoms; R.sub.2 and R.sub.6 each represents an alkyl group having from 2 to 4 carbon atoms; R.sub.3 represents an alkyl group, an aryl group, a halogen atom, an alkoxy group, a hydroxy group, an acyloxy group or an alkoxycarbonyloxy group; n represents an integer from of 1 to 5, when n is 2 or more, two or more R.sub.3 's are the same or different; R.sub.4 represents a hydrogen atom or an alkyl group having not more than 16 carbon atoms; R.sub.5 represents a hydrogen atom or an alkyl group having not more than 4 carbon atoms; m represents an integer of from 1 to 4; X.sub.1 and X.sub.2 each represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group or an acylamino group; and Z.sub.1 and Z.sub.2 each represents a hydrogen atom or a group capable of being released upon a coupling reaction with a developing agent.
The silver halide color photographic material has a high dye forming rate and provides a high maximum color density even when a color developing solution which does not contain benzyl alcohol is used, exhibits substantially no reduction in color density in the case of processing in a bleaching solution having a weak oxidation power or an exhausted bleaching solution, and forms color images having excellent and well balanced fastness to heat and light.
