Abstract

1,040,081. Developer compositions. ILFORD Ltd. June 22,1965 [June 24,1964],No. 26127/64. Addition to 999,145. Heading G2C. A photographic developer composition comprises a silver halide developing agent, an alkali metal hydroxide and/or carbonate, 2, 3-dihydroxy- 1, 4-dioxane, a water-soluble borate e.g. borax or boric acid and diacetyl. Specified developers are metal, hydroquinone, 1-phenyl -3-pyrazolidone and its 4-methyl or 4, 4-dimethyl derivatives gentisic acid or ascorbic acid or mixtures thereof. The composition may contain an additional hardener e.g . acetonyl acetone; antifoggants e.g. benzotriazole, 6-nitro-benzimidazole or 1 -phenyl- 5 -mercapto tetrazole; sulphites and bisulphites and development restrainers e.g. potassium bromide.
