Abstract

1395713 Photographic process IMPERIAL CHEMICAL INDUSTRIES Ltd 10 Aug 1972 [19 Aug 1971] 38934/71 Heading G2C A process of producing a permanent coloured non-metal image from an unstable coloured image formed by imagewise exposing a salt of Formula:- wherein R<SP>1</SP>-R<SP>10</SP> are H, halogen, or organic radicals, R<SP>1</SP><SP>1</SP> and R<SP>12</SP>, if present, are halogen or organic, Z is 0 or an integer, X is an anion of an acid of pKa less than 2.5, m is 1 or 2 and at least one of the nitrogen atoms is quartenary; the process comprises contacting the unstable image with a water-soluble compound which is reduced by the image to form a water-insoluble coloured image. Metal images produced from such salts by electroless deposition are disclosed in Specification 1385962. Specified water-soluble compounds are tetrazolium salts, as disclosed in Specification 908299, phthalocyanise precursors as in Specification 873054 and ferric ferricyanide. The photographic materials are those disclosed in Specification 1310812.
