In the dye diffusion transfer process for the production of colored images dye-providing compounds of the following formula give lower color fog values Dmin, as compared with known dye-providing compounds: <IMAGE> X = dye or dye precursor Z = intermediate member n = 0 or 1 R1 = -O-R2; -S-R2 or <IMAGE> R2 = hydrogen, alkyl, cycloalkyl or aryl R3 = a group as defined under R2 or acyl R4 = hydrogen or alkyl Y = a residue to complete a condensed benzene ring and R1 and/or a substituent on the condensed benzene ring is or contains a group that confers resistance to diffusion.
