ABSTRACT:
A photosensitive element comprising a support having thereon at least one photosensitive silver halide emulsion layer and one of said layers having associated therewith a yellow image dye-releasing compound having a formula as follows ##STR1## wherein Car represents a sulfonamidophenol or sulfonamidonaphthol carrier moiety which, as a function of oxidation under alkaline conditions, releases a diffusible dye from said compound.
X represents a bivalent linking group of the formula --R.sup.1 --L.sub.n --R.sup.1.sub.p -- where each R.sup.1 can be the same or different and each represents alkylene phenylene; or substituted phenylene; L represents a bivalent radical selected from oxy, carbonyl, carboxamido, carbamoyl, sulfonamido, sulfamoyl, sulfinyl or sulfonyl; n is an integer having a value of 0 or 1; p is 1 when n equals 1 and p is 1 or 0 when n equals 0, provided that when p is 1 the carbon content of the sum of both R radicals does not exceed 14 carbon atoms;
R represents hydrogen or alkyl;
J represents a bivalent radical selected from sulfonyl or carbonyl;
m and q each represent an integer having a value of 0 or 1;
E represents hydrogen, halogen, alkyl or alkoxy;
Z represents hydrogen or an electron withdrawing group selected from cyano, trifluoromethyl, alkylsulfonyl, substituted alkylsulfonyl, phenylsulfonyl, or substituted phenylsulfonyl; a carboxylic acid ester having the formula --COOR.sup.2 wherein R.sup.2 is alkyl, phenyl or substituted phenyl; sulfo, a sulfamoyl radical having the formula --SO.sub.2 NR.sup.3 R.sup.4 wherein R.sup.3 represents hydrogen or alkyl, and R.sup.4 represents hydrogen, alkyl, substituted alkyl; benzyl, phenyl, substituted phenyl; alkylcarbonyl, or phenylcarbonyl, with the proviso that the carbon content of the sum of R.sup.3 and R.sup.4 not exceed 14 carbon atoms; a carbamoyl radical having the formula --CON(R.sup.3).sub.2 wherein each R.sup.3 can be the same or different and is as described previously; and
M represents hydrogen, a solubilizing group or precursor thereof selected from carboxy, sulfo, a sulfamoyl radical as described for Z or a carboxylic acid ester as described for Z.
