Abstract

1,148,483. Photographic dispersions. EASTMAN KODAK CO. April 15, 1966 [April 15, 1965], No.35567/68. Divided out of 1,148,482. Heading G2C. An aqueous dispersion of physical development nuclei has a peptising agent for the nuclei comprising a homopolymer of units of formula 1 or 2 (as defined below), or a copolymer of units of formula 1 or 2 and units of formula 3 in which the ratio of the total number of units to the number of units of formula 1 or 2 is not above 5:1. Formulae 1 and 2 are and formula 3 is wherein # is the repeating unit of a hydrophillic polysaccharide, e.g. α-amylose, or a hydrolyzed cellulose acetate; R 1 and R 2 are each alkyl of 1-8 C atoms, or aryl, or together form a heterocyctic ring which may contain further N, O or S atoms; R 3 is alkyl of 1-6 C atoms; and B and D are each H, OH, alkyl, aryl, acyl, acyloxy, cyano, diacylimido, alkyloxy, aryloxy, carbonyl or carboxy. The dispersion may be coated to form imagereceiving layers for the silver salt diffusion process, and may also contain gelatine in a gelatine: polymer ratio of 99À1. The polymers also have a black-toning effect on the transferred image.
