Abstract
761,301. Photographic developers. ILFORD, Ltd. Aug. 10, 1955 [Aug. 24, 1954], No. 24607/54. Class 98(2) A photographic developer comprises an alkaline solution containing p-hydroxyphenylaminoacetic acid and a 3-pyrazolidone, e.g. 1-phenyl-3-pyrazolidone and its 4-methyl-, 4-ethyl-, 5-methyl-, and 4: 4-dimethyl-derivatives. In examples, developers specified are solutions of p-hydroxyphenylaminoacetic acid, 1-phenyl-3- pyrazolidone (or, in Example 2, 1-phenyl-4- methyl-3-pyrazolidone or 1-phenyl-4:4-dimethyl-3-pyrazolidone), and, in Examples 1 and 2, sodium sulphite, borax and sodium carbonate, in Example 3, potassium sulphite and caustic soda, and, in Example 4, potassium sulphite, potassium bromide and potassium hydroxide. The use in the developers of ammonium and alkylolamine sulphites, sodium and potassium metabisulphites, benztriazole, and 1-phenyl-5 mercapto-tetrazole is referred to. Specification 542,502 is referred to.
