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 compound represented by the following general formula (I): ##STR1## wherein X.sup.1 represents --J--NR.sup.2 -- or --NR.sup.2 --J-- wherein R.sup.2 represents a hydrogen atom or an alkyl group, and J represents --SO.sub.2 -- or --CO--; R.sup.1 represents an alkyl group; X.sup.2 represents --R.sup.3 --L).sub.k (R.sup.4).sub.e -- wherein R.sup.3 and R.sup.4, which may be the same or different, each represents an alkylene group, a substituted alkylene group, a phenylene group or a substituted phenylene group, L represents --O--, --CO--, --SO.sub.2 NH--, --CONH--, --NHSO.sub.2 --, --NHCO--, --SO.sub.2 -- or --SO--, k represents 0 or 1, and e represents 1 when k is 1, or 1 or 0 when k is 0, provided that when X.sup.2 bonds to X.sup.1, X.sup.1 bonds to R.sup.3 ; i and j each represents 0 or 1; and Y represents a moiety which provides, as a result of development processing under alkaline conditions, an azo dye compound having a different diffusibility from that of the azo dye image-forming compound represented by the formula (I).
