Abstract
878,675. Photographic processes. KODAK Ltd. Nov. 1, 1957 [Nov. 5, 1956], No. 34118/57. Class 98(2) A photographic colour developer comprises an alkaline solution of an aromatic primary amino developing agent, an alkali metal sulphite, a hydroxylamine salt, an ethylene diamine salt and 1, 3-diamino-2-propanol tetracetic acid. The alkali may be sodium metaborate, carbonate or hydroxide. An example is given wherein the developer is 4-amino-N-ethyl-N-[#-methylsulphonamidoethyl]-m-toluidine sesquisulphate and the other organic salts are the sulphates. A black and white metol/hydroquinone developer contains sodium hexametaphosphate, metaborate, sulphite and chloride, and 5-methylbenztriazole. A stop bath for use after black and white or colour development comprises sodium diacetate and bisulphite, to which may be added sodium acetate, boric acid and potassium aluminium sulphate. A fixing solution contains hypo, sulphite, acetic acid, potassium aluminium sulphate and zinc sulphate. Specifications 725,573 and 804,662 are referred to.
