Abstract
Abstract A color photographic material comprising a support having thereon a silver halide emulsion layer containing a coupler which can form a dye by the coupling reaction with the oxidation product of an aromatic primary amino developing agent and which contains a alkoxycarbonylarylene group represented by the formula wherein R1 and R2 represent a hydrogen atom or an alkyl group, R3 represents an aryl group, Ar represents an arylene group, and n represents an integer of from 1 to 7.
