| abstract | 1,061,053. Processing photographic silver halide emulsions. OZALID CO. Ltd., A. J. O. AXFORD and F. S. SUTTON. Aug. 13, 1963 [May 17, 1962], No.19058/62. Heading G2C. An exposed and developed photographic silver halide emulsion is stabilized by treatment with a solution of ammonium or alkali-metal thiocyanate and a solution of a 4-aryl-2-hydroxy-tetronic acid or its imide, such as 4-sulphophenyl-2- hydroxy-tetronimide, in either order, or with a solution containing both the thiocyanate and tetronic acid or imide. The emulsion may contain a developer such as hydroquinone and be developed by treatment with alkali. The tetronic acid or imide prevents subsequent discolouration of the thiocyanate-stabilized image. |
