Abstract

1291533 Processing photographic silver halide materials VISUAL GRAPHICS CORP 10 Feb 1971 [13 Feb 1970] 4388/71 Heading G2C Exposed photographic silver halide material is processed by treatment at 75‹ to 125‹F. with a first development bath containing about 4À7% by weight of hydroquinone, a second development bath free from developing agent but having a high pH, a fixer containing for example ammonium thiosulphate and ammonium thiocyanate, a wash solution containing dilute ammonium thiosulphate, and if desired a glycerine solution.
