Substituted 4-nitrophenylazo-1-naphthol cyan dyes having improved light stability

In a photographic assemblage comprising:

• (a) a photographic element comprising a support having thereon the following layers in sequence:
• a dye image-receiving layer, a stripping layer, a substantially opaque layer and a photosensitive silver halide emulsion layer having associated therewith a dye image-providing material,
• (b) a transparent cover sheet superposed over said silver halide emulsion layer, and
• (c) an opaque alkaline processing composition and means containing same for discharge, during processing, between said cover sheet and said photosensitive element,
• the improvement wherein said dye image-providing material is a nondiffusible compound capable of releasing at least one diffusible cyan dye moiety, said compound having the formula:
• ##STR88## wherein:
• (a) J represents SO.sub.2 or CO,
• (b) R represents a substituted or unsubstituted alkyl group of from 1 to about 10 carbon atoms or a substituted or unsubstituted aryl group of from 6 to about 12 carbon atoms,
• (c) G represents a hydroxy group, a salt thereof, or a hydrolyzable precursor thereof,
• (d) CAR represents a ballasted carrier moiety capable of releasing said diffusible dye moiety as a function of development of said silver halide emulsion layer under alkaline conditions, and
• (e) D.sup.1, D.sup.2, and D.sup.3 each independently represents H or one or more electron-withdrawing groups selected from --SO.sub.2 Y.sup.1, --CONY.sup.1 Y.sup.2, --Cl, --COY.sup.1, --C.tbd.N and --SO.sub.2 NY.sup.1 Y.sup.2, where Y.sup.1 and Y.sup.2 each independently represents hydrogen, a substituted or unsubstituted alkyl group of from 1 to about 10 carbon atoms or a substituted or unsubstituted aryl group of from 6 to about 12 carbon atoms.
