Abstract

1,236,690. Colour photographic light-sensitive halide elements, FUJI PHOTO FILM CO. Ltd. May 13, 1969 [May 13, 1968], No. 24386/69. Heading G2C. A colour photographic light-sensitive element has on a support a silver halide emulsion layer containing a diffusion-resistant 4-azo-pyrazolone colour coupler having the general formula: - wherein R 1 and R 3 each represents an aryl group which may be substituted, or a heterocyclic group which may be substituted, and R 2 represents an alkyl group which may be substituted, an aryl group which may be substituted, or an amino, acylamino, ureido or suphonylamino group each bonded to an alkyl group which may be substituted, or an aryl group which may be substituted, and a colour coupler which is a diffusion-resistant colourless phenol derivative or a diffusion-resistant colourless α-naphthal derivative. Many examples are given of the three types of colour coupler referred to above. The object of the present invention is to provide a colour photographic light-sensitive element capable of giving image patterns of high contrast and good colour saturation, and to provide by a simple process coloured image patterns, from originals in black and white.
