Abstract (en)
[origin: US4464464A] The color yield and color granularity of color photographic recording materials is improved by using compounds of the general formula I as the sole or as additional oil formers in coupler-containing internal layers. The effect is particularly clear in layers having the small amount of gelatine. <IMAGE> I wherein: R1 is an aliphatic group having at least 8 carbon atoms, R2 is hydrogen or alkyl, R3 is a heterocyclic group or -(X)n-R4, R4 is aryl, X is -O-, -NH-, -NCH3-, or -CH=CH-, m is 0, 1 or 2, and n is 0 or 1.
