Abstract
Abstract WHEREIN Ar and Ar1 are an aryl group and X is hydrogen or a group capable of being released at the time of color development, is produced which is high in coupling reactivity, have spectral absorption characteristics suitable for the color reproduction principle of the tricolor substractive color photography and form dye images which are stable to heat, light and humidity. A yellow coupler of the general formula:
