Abstract

1,146,719. Photographic anti-foggant. GENERAL ANILINE & FILM CORP. June 14, 1966 [June 25, 1965], No.26513/66. Heading G2C. Photo-sensitive silver halide materials contain, or are processed in the presence of, ananti-foggant of formula wherein X is a halogen and R and R<SP>1</SP> are halogen or a cation (e. g. Na<SP>+</SP> , Ag<SP>+</SP>, or ammonium or an organoammonium cation). The anti-foggant may be in the light-sensitive layer (optionally admixed with sulphamic acid and/or an ethylene oxide condensate) or a layer adjacent thereto, a predevelopment solution or the developer (e. g. a hydroquinone, Metol/hydroquinone, or borax type).
