ABSTRACT OF THE DISCLOSURE The disclosure describes a silver halide color photographic light-sensitive material comprising a reflective support bearing thereon a green light sensitive silver halide emulsion layer containing a magenta forming coupler represented by Formula (I): a blue light-sensitive silver halide emulsion layer containing a yellow-forming coupler represented by the following formula (II); and a red light-sensitive silver halide emulsion layer containing a cyan-forming coupler represented by the following Formula (III) or (IV). Formula I, II, III and IV are as follows: Formula (I) Image wherein R1 represents a tertiary alkyl group; R2 represents an alkyl group or an aryl group; and X represents a split-off group other than hydrogen, which is capable of splitting off through a reaction with the oxidation products of a color developing agent. Formula (II) Image wherein X1 represents a halogen, an alkoxy group or an alkyl group; Y1 represents a group capable of splitting off when a dye is formed by coupling the group with the oxidation products of an aromatic primary amine color developing agent; R4 represents a group substitutable to a benzene ring; and n is an integer of 1 or 2. Formula (III) Image wherein R5 represents an alkyl group having 1 to 4 carbon atoms; R6 represents hydrogen or an alkyl group having 1 to 15 carbon atoms, and R7 represents a halogen, an alkyl group, a hydroxy group or an acyloxy group. Formula (IV) Image wherein R8 represents an alkyl group, a halogen, a sulfonamido group, a sulfamoyl group, an arylsulfonyl group, or a hydroxy group; R9 represents hydrogen or an alkyl group; and R10 represents hydrogen, a halogen, an alkyl group, a sulfamoyl group or a sulfonamido group. This material is capable of remaining stable for a long time especially when it is irradiated by light. It is also capable of displaying an excellent color development.
