Photographic light-sensitive sheet for the color diffusion transfer

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 having associated therewith a dye image providing material represented by the following general formula: ##STR1## wherein Q.sup.1 represents a hydrogen atom, a halogen atom, a sulfamoyl group represented by the formula --SO.sub.2 NR.sup.3 R.sup.4 wherein R.sup.3 represents a hydrogen atom or an alkyl group; R.sup.4 represents a hydrogen atom or 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; a group represented by the formula --SO.sub.2 R.sup.5 wherein R.sup.5 represents an alkyl group or a benzyl group; a carboxy group, a group represented by the formula --COOR.sup.6 wherein R.sup.6 represents an alkyl group, a phenyl group or a substituted phenyl group or a group represented by the formula --CONR.sup.3 R.sup.4 wherein R.sup.3 and R.sup.4 each has the same meaning as defined above; Q.sup.2 is positioned at the 5- or the 8-position to the hydroxy group and represents a hydroxy group, a group represented by the formula --NHCOR.sup.4a or a group represented by the formula --NHSO.sub.2 R.sup.4a wherein R.sup.4a has the same meaning as R.sup.4 defined above, except for the absence of a hydrogen atom; R.sup.1a represents an alkylene group having 2 or more carbon atoms; R.sup.2a 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; X.sup.1 represents a divalent bonding group represented by the formula --A.sub. 1 --(L).sub.n --(A.sub.2).sub.p -- wherein A.sub.1 and A.sub.2 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 ##STR2## 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.
