摘要: A color photographic recording material having at least one spectrally sensitized silver halide emulsion layer, characterized in that said silver halide emulsion layer contains an oil former having a pKa value of less than 18 and a DIR coupler and the material contains at least one color coupler, wherein the color coupler and/or the DIR coupler have specific structures, is distinguished by an increased interimage effect in comparison with the prior art without sensitivity being reduced.
