More Information
Summary:A color photographic light-sensitive material which comprises a support having thereon at least one silver halide emulsion layer containing a coupler represented by the following general formula (I) wherein Q represents a coupler residue which can form a dye on reaction with an oxidation product of an aromatic primary amino developing agent; R1 represents an alkyl group, an aralkyl group, an alkoxy group, an alkoxyalkyl group, an acylamido group or an alkoxycarbonyl group, each having from 4 to 20 carbon atoms; R2 represents a hydrogen atom, a chlorine atom, a hydroxy group, an alkyl group having 1 to 5 carbon atoms or an alkoxy group having 1 to 5 carbon atoms; m represents an integer of 1 to 4; n represents an integer of 1 to 4; and the sum of m + n is 2 to 5; and R1 and R2 can combine to form a non-metallic atom-containing five membered or six membered ring. These couplers have excellent solubility in coupler solvents and good stability to heat.
