Abstract

1401112 Photographic silver halide developers FUJI PHOTO FILM CO Ltd 30 April 1973 [28 April 1972] 20566/73 Heading G2C A developer for the infectious development of photographic silver halide materials which contains a dihydroxybenzene developing agent, an alkali, 0.005 to 0.05 mole per litre of free sulphite, a sulphite ion buffer and at least 10 mg. per litre of the solution of a compound of the Formula:- wherein Z completes a 5- or 6- membered heterocyclic ring containing N, S, and/or O atoms and which may be fused to another ring and in which either ring may be substituted, X is hydrogen, alkyl or a cation and n is 1, 2 or 3. Specified compounds include 3-mercapto-4-phenyl-1:2:4- triazole, 5-ethyl-3-mercapto-4-phenyl-1:2:4- triazole, 6-undecyl- and 6-t-butyl-1:3:3a:7- tetrazaindene-4-thiols, 2-benzyl-6-methyl-1:3:3a:7- tetrazaindene-4-thiol and 2-methylthio-4-hydroxy- 6-methyl-1:3:3a:7-tetrazaindene. The compounds reduce bromide streaking in the automatic processing of lith materials. Reference has been directed by the Comptroller to Specification 1312864.
