Abstract

1306176 Photographic Developer MINNESOTA MINING & MFG CO 11 June 1971 [12 June 1970] 27600/71 Heading G2C A photographic developer for silver halide material comprises an oxidisable developing agent and an oxidation inhibitor of the general formula R<SP>1</SP> -CO-[CH 2 ] n -CHOH-R<SP>2</SP> in which R<SP>1</SP> is an alkyl group or the group - CH 2 OH, R<SP>2</SP> is a hydrogen or an aliphatic group, or R<SP>1</SP> and R<SP>2</SP> together represent the atoms necessary to complete a cycloaliphatic ring, and n is O or 1. Specified inhibitors are hydroxyacetone, dihydroxyacetone and its dimer, 3-hydroxy -2- butanone, 4-hydroxy-2- butanone and 2-hydroxy-cyclohexanone. The developing agent may be hydroquinone, 1-phenyl-3-pyrazolidone, pyrogallal, an aminophenal or a di-aminophenal or a derivative thereof or a mixture of two or more of these. A colour developing agent such as para-phenylene-diamine or a derivative thereof may be used. Examples of suitable developer compositions are given.
