Abstract

Abstract A light-sensitive photographic element comprising a support and at least one light-sensitive silver halide emulsion layer coated thereon having associated therewith a magenta image dye-providing compound which releases a magenta dye or a precursor thereof corresponding to the imagewise exposure of said emulsion layer, said magenta dye-providing compound being a compound represented by formula [I]: ##STR1## wherein Car represents a carrier moiety which can be oxidized under alkaline conditions to release a diffusible dye or a precursor thereof from said compound; R 1 and R 2 , which may be the same or different, independently represent a hydrogen atom or an alkyl group having 1 to 3 carbon atoms (provided that the total sum of carbon atoms in R 1 and R 2 does not exceed 5), or R 1 and R 2 may form, together with the nitrogen atom, ##STR2## X represents a hydroxyl group, a salt thereof or a group, which can be converted into a hydroxyl group by hydrolysis, having the following formula: ##STR3## in which R 3 represents an alkyl or haloalkyl group having 1 to 18 carbon atoms or a phenyl group which may be substituted; Y represents a ##STR4## group in which R 4 and R 5 , which may be the same or different, independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms or a cycloalkyl group (provided that the total sum of carbon atoms in R 4 and R 5 does not exceed 6); Z represents a hydrogen atom, a chlorine atom, a methyl group or a methoxy group; l is 1 or 2 provided that when l is 2 each Z may be the same or different; m is 0 or 1; and J represents a bivalent linking group having the formula --R 6 --(O) n --R p 7 -- in which R 6 and R 7 , which may be the same or different, independently represent an alkylene group having 1 to 8 carbon atoms, a phenylene group which may be substituted; n represents 0 or 1; p represents 0 or 1 provided that p is 1 when n is 1 and 1 or 0 when n is 0 (provided that, when p is 1, the total sum of carbon atoms in R 6 and R 7 does not exceed 13).
