    摘要: Process for the production of color images by the color photographic dye diffusion process in which development is brought about by heat and water. The combination of antifoggants added to the light-sensitive material, in particular the combination of compounds of formulae I and II, produces a marked improvement in storage stability and constancy of sensitivity with good D.sub.min /D.sub.max ratios. ##STR1## R.sup.1 denotes hydrogen, alkyl with up to 6 carbon atoms, hydroxy, halogen, alkoxy or substituents which together form a condensed benzene ring, and in formula II below: ##STR2## R.sup.2 denotes a group which can be split off in the process of development of the material andR.sup.3 denotes hydrogen, halogen, alkyl with up to 4 carbon atoms, alkoxy, carboxy, carbalkoxy, carbonamido or sulphonamido.
