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:

• ##STR55## 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.l wherein R.sup.3 and R.sup.4, which may be the same or different, each represents an alkylene group, or a 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 l 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), wherein said photographic light-sensitive sheet further contains a dye image-forming compound represented by the following formula (X):

• 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.14a or a group represented by the formula --NHSO.sub.2 R.sup.14a wherein R.sup.14a has the same meaning as defined above;
• R.sup.11a and R.sup.11b, which may be the same or different, each represents an alkylene group having 2 or more carbon atoms provided that the two oxygen atoms in the --O--R.sup.11a and --OR.sup.11b --OR.sup.12b moiety are not connected to the same carbon atom;
• R.sup.12a and R.sup.12b, which may be the same or different, each represents an alkyl group, m 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 (X).
