Abstract
1380795 Heat-developable photographic material AGFA GEVAERT AG 17 Aug 1972 [17 Aug 1971] 38387/72 Heading G2C The light-sensitive layer of a heat-developable photographic material comprises a light-sensitive metal salt, a light-insensitive reducible silver salt, a reducing agent and as toner a phthalic acid imide of the formula: . wherein R represents hydrogen, an alkyl or alkoxy group containing up to 6 carbon atoms, a cycloalkyl or cycloalkoxy group, or an aralkyl or aralkoxy group. 0À5-6 mol of phthalimide per mol of light-insensitive silver compound may be present in the light-sensitive layer. The phthali - mide may also be present in a layer adjacent to the light-sensitive layer.
