Abstract

Colored, reflection-viewed images having improved stability to light, heat and moisture and improved storage stability while retaining the original color character thereof are produced using color photographic recording materials containing, on a light-reflecting layer support, a red-sensitive, a green-sensitive and a blue-sensitive silver halide emulsion layer, each with spectrally associated color coupler, the yellow coupler being a 2-equivalent yellow coupler derived from pivaloyl acetanilide, the magenta coupler a 3-anilinopyrazolone coupler and the cyan coupler a coupler corresponding to the following general formula (I): ##STR1## wherein R.sup.1 represents H or halogen; PA1 R.sup.2 represents alkyl having at least 2 carbon atoms; PA1 R.sup.3 represents H or alkyl having up to 5 carbon atoms; PA1 R.sup.4 represents acyl; and PA1 X.sup.1 represents H or a group releasable in the process of color coupling.
