Novel color forming couplers for use in silver halide color photography are described. These couplers upon oxidative coupling with an aromatic primary amino color developing agent produce dyes of improved stability against light and dyes having favorable spectral absorption characteristics. The couplers have high coupling activity and thus produce high color densities. The novel couplers are acylacetanilide compounds whereof the phenyl nucleus of the anilide group carries oxyhydrocarbon groups, preferably alkoxy groups in the 2-, 4- and 5-position with respect to the amido group.
