Abstract
1315498 Photographic silver halide development AGFA-GEVAERT 22 Sept 1970 [27 Oct 1969] 52568/69 Heading G2C An exposed photographic silver halide emulsion layer is developed with an aqueous alkaline composition in the presence of a substituted or unsubstituted N, N-dialkylhydroxylamine developing agent and a quaternary ammonium compound of the formula:- wherein Q<SP>+</SP> completes a cydic or acyclic quaternary ammonium group; R is a 7-20C alkyl group or the group Q<SP>+</SP>]X<SP>-</SP>; X<SP>-</SP> is an anion; n is an integer from 1-250 with the proviso that n is at least 2 when R is alkyl; and x is 2 when n is different from 1 and is an integer from 2-16 when n is 1. This process may be used in the silver salt diffusion transfer process (see Example 2). The developing agent and the quaternary ammonium compound are both preferably present in the developing composition. Development is accelerated by use of this combination of developing agent and quaternary ammonium compound.
