Abstract

1,158,849. Optically sensitized emulsions. EASTMAN KODAK CO. Nov.28, 1966 [Nov. 26, 1965], No.53239/66. Heading G2C. Blue-sensitized silver halide emulsions, particularly in multi-colour materials, in which the blue-sensitive layer is nearest the support comprise a colour coupler and sensitizing dyes of the formula;- wherein R and R<SP>1</SP> represent alkyl (substituted or unsubstituted), or aryl, L represents methine (substituted or unsubstituted), n is 1 or 2, m is 1 or 2, d is 1 or 2, Q 1 is O 1 S or -N-R 3 wherein R 3 is alkyl (substituted or unsubstituted) or aryl, Q represents the non-metallic atoms necessary to complete an heterocyclic nucleus containing 5 atoms in the heterocyclic ring said heterocyclic nucleus containing at least one group selected from sulphoalkyl, sulpho alkoxy alkyl and the salt forms of such groups and Z represents the non-metallic atoms necessary to complete an heterocyclic nucleus containing 5 or 6 atoms in the heterocyclic ring.
