Abstract
1,157,617. Photographic developers. KODAK Ltd. Dec. 8, 1966 [Sept. 9, 1965], No. 38636/65. Addition to 1, 093, 281. Heading G2C. [Also in Division C2L] Silver halide developing Compounds of formula;- in which R 1 is a hydroxyalkyl group, R 2 is a hydroxayalkyl, alkyl or substituted alkyl group, in which the alkyl group contains up to 4 carbon atoms and R 3 is an aryl group are used as constituents of photographic silver halide developer concentrates. Examples are given of photographic developer solutions containing 4-hydroxymethyl-4- methyl-1 -phenylpyrazolid-3-ore.
