Abstract
811,185. Photographic colour developmeat. ILFORD Ltd. July 29, 1957 [Oct. 3, 1956], No. 30156/56. Class 98(2) An exposed silver halide emulsion layer, especially one in a multilayer colour material comprising also one or more layer containing an unexposed and non- developable silver halides, is colour developed in an alkaline solution comprising an aromatic primary amino developing agent, a colour coupler, and a 3 - pyrazolidone developing agent. Hydroxylamine also may be present in the developer as described in Specification 805,174. The 3 - pyrazolidone may be one of those described in Specifications 542,502 and 757,271, and the primary amino developer may be N, N - diethyl p - phenylene diamine or 2 - amino - 5 - diethylamino toluene. Examples are given of developer compositions comprising 2 - amino - 5 - diethylamino toluene, 1 - phenyl - 3 - pyrazolidone hydroxylamine hydrochloride, sodium carbonate or sodium phosphate as alkali (with sodium hexametaphosphate when sodium carbonate is used) and, as colour coupler; 1 - hydroxy - 2 - naphthoyl - cyclohexamide, furoyl - acet - o - toluidine or 1 - p - nitrophenyl - 3 - methyl - 5 - pyrazolone. Specification 500,613 also is referred to.
