ABSTRACT:
A photographic light-sensitive sheet for the color diffusion transfer process which comprises a support having thereon at least one light-sensitive silver halide emulsion layer with at least one of said silver halide emulsion layers having associated therewith a compound represented by the following general formula (I): ##STR1## wherein Q represents a cyano group, a trifluoromethyl group or a carbamoyl group represented by the formula --CONR.sup.3 R.sup.4 wherein R.sup.3 represents a hydrogen atom or an alkyl group; R.sup.4 represents a hydrogen atom, an alkyl group, an aralkyl group or an aryl group; and R.sup.3 and R.sup.4 may combine directly or through an oxygen atom to form a ring; M represents a hydrogen atom, an alkyl group, an alkoxy group, a sulfamoyl group represented by the formula --SO.sub.2 NR.sup.3 R.sup.4, wherein R.sup.3 and R.sup.4 are as defined above, a group represented by the formula --COOR.sup.5 wherein R.sup.5 represents an alkyl group, a phenyl group or a substituted phenyl group; or a halogen atom; R.sup.1a and R.sup.1b, which may be the same or different, each represents an alkylene group having 2 or more carbon atoms; R.sup.2a and R.sup.2b, which may be the same or different each represents an alkyl group, Y represents a moiety which releases or provides, as a result of development processing under alkaline conditions, an azo dye having a different diffusibility from that of said dye image-providing material and m represents 0 or 1.
The compound is a dye image providing material which provides a yellow dye image having excellent properties.
