PURPOSE:To improve the color tone of a yellow dye releasing compound for a diffusion transfer method by adding a carboxy group as a group convertible into a metallic complex on the benzene ring at the azo dye part and further adding an electron attractive group to the 3-position of the pyrazolone ring. CONSTITUTION:To an emulsion layer is added a compound represented by general formulaI(where G<1> is carboxy, its salt or a hydrolyzable precursor of the salt, G<2> is OH, its salt or a hydrolyzable precursor of the salt, X is an electron donative group or an electron attractive group having <+0.54 Hammett's value (sigma), l is an integer of 0-6, Y is an electron attractive group, Z is a ballasted carrier part releasing a dye as a function of silver halide development under an alkaline condition, S is sulfoxy, sulfamoyl or H, m is an integer of 1-3, J is a bivalent bonding radical, and n is 0 or an integer of <=m). |
