Abstract

1,035,034. Photographic development. POWERS CHEMCO Inc. March 4,1963 [May 14, 1962], No. 8509/63. Heading G2C. A replenisher solution for a photographic alkaline aldehyde-bisulphite bath in which the sole developing agent is hydroquinone contains sulphite and hydroxyl ions. The sulphite ions may be provided by an alkali metal sulphite or bisulphite and the hydroxyl ions by an alkali metal hydroxide, carbonate or borate. The developer bath may contain an alcohol, glycol or an ethylene glycol monomethyl or monoethyl ether and/or ethylene diamine tetracetic acid.
