F2A-20446/YN/78 ABSTRACT OF THE DISCLOSURE 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 having associated therewith a dye image providing material represented by the following general formula: Image wherein Ql is selected from the group consisting of (a) a hydrogen atom, (b) a halogen atom, (c) a sulfamoyl group represented by the formula -SO2NR3R4 wherein R3 represents a hydrogen atom or an alkyl group, R4 represents a hydrogen atom or an alkyl group, an aralkyl group or an aryl group, and R3 and R4 may combine directly or through an oxygen atom to form a ring; (d) a group represented by the formula -SO2R5 wherein R5 represents an alkyl group, a benzyl group or a carboxy group, (e) a group represented by the formula -COOR6 wherein R6 represents an alkyl group, a phenyl group or a substituted phenyl group, and (f) a group represented by the formula -CONR3R4 wherein R3 and R4 each has the same meaning as defined above; Q2 is positioned at the 5- or the 8-position to the hydroxy group and represents a hydroxy group, a group represented by the formula -NHCOR4a or a group represented by the formula -NHSO2R4a wherein R4a has the same meaning as R4 defined hereinbefore, except that R4a does not represent a hydrogen atom; Rla represents an alkylene group having 2 or more carbon atoms; R2a 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; m is 0 or 1; q is 0 or 1; J represents a divalent group selected from a sulfonyl group and a carbonyl group; Z represents a hydrogen atom, an alkyl group or a substituted alkyl group; Xl represents a divalent bonding group represented by the formula -Al-(L)n-(A2)p- wherein Al and A2 are the same or different and each represents an alkylene group or an arylene group; L represents a divalent group selected from an oxy group, a carbonyl group, a carboxyamido group, a carbamoyl group, a sulfonamido group, a sulfamoyl group, a sulfinyl group and a sulfonyl group, and n and p each represents 0 or 1; and G represents a hydroxyl group, a salt thereof, or a hydrolyzable acyloxy group represented by the formula Image or Image wherein E represents an alkyl group, a substituted alkyl group or an aryl group. The compound is a dye image providing material which provides a magenta dye image having superior properties.
