摘要： A reflective silver halide photographic light-sensitive material is disclosed. The light-sensitive material comprises a reflective support having thereon a silver halide emulsion layer wherein the support have an oxygen permeability of not more than 2.0 ml/m.sup.2 .multidot.hr.multidot.atm and the silver halide emulsion layer contains a magenta coupler represented by the following Formula I; ##STR1## wherein Ar is an aryl group; Y is a hydrogen atom or a substituent capable of splitting off upon reaction with the oxidation product of a color developing agent; X is a halogen atom, an alkoxy group or an alkyl group; R is a strait- or branched-chain alkyl group having 1 to 20 carbon atoms; J is a strait- or branched-chain alkylene group; and n is an integer of from 0 to 4, when n is 2 or more, the plurality of Xs may be the same or different. The light-sensitive material is excellent in red color reproducibility and light fastness of red colored images.
