Abstract

Multi-layer colour materials using colour couplers which contains two red sensitising dyes in the red sensitive layer above which is a purple or red colour filter layer. Improved colour reproduction results particularly in the purity of colours. Red sensitising dyes referred to in the example are 2-(3-ethyl-5-phenyl-benzoxazolyl) 2'-(3'-gamma-sulphopropyl-5',6'-dimethoxybenzselenazolyl)-9-ethyl- -carbocyanine; 3-ethyl-6'-S sulphobutyl-5: 5'-dimethyl-9-ethyl-thiocarbocyanine and 3: 3'-diethyl-9-methyl-selenacarboxyamine iodide.
