Abstract

1,205,745. 745. Hardening photographic silver halide emulsions. EASTMAN KODAK CO. Jan.12, 1968 [Oct.14, 1966], No.45957/66. Heading G2C. A photographic silver halide emulsion, in which the binder is gelatine or a synthetic hydrophilic polymer such as an ethyl acrylate -acrylic acid copolymer or a mixture thereof, is hardened by adding a compound of the formula:- in which n is 0 or 1, R is alkyl of 1 to 6 carbons or the group -CH 2 -CH 2 -0-S-O M , Q is a divalent radical having from 1 to 10 aliphatic carbon atoms, M is an ammonium, alkali metal or alkaline earth metal ion, and X is an anion, or a zwitterion derived from a compound of the above general formula by the removal of one or more molecules of MX. The compound also acts an an antifoggant. The disodium salt of tris-(beta-sulphatoethyl) sulphonium inner salt is specified.
