Abstract
1355625 Heat-developable photographic material MINNESOTA MINING and MFG CO 31 Jan 1972 [2 Feb 1971] 4482/72 Heading G2C In heat developable photographic material having one or more coating layers including a light-stable oxidisable silver salt, a reducing agent therefor and a small proportion of a photosensitive silver halide as catalyst, there is also included a photo-sensitive halogen-containing organic oxidising agent as stabilizer. The reducing agent may be 2, 2' -methylene bis- (4-methyl-6-tertiary-butylphenol). The stabilizer may be 1, 2, 3, 4-tetrabromobutane, hexabromoethane, tribromoquinaldine, or 1, 2, 3, 4-hexabromocyclohexane. 0À5-3À5 mols of stabilizer per mol of silver halide may be employed. The constituents may be contained in a single layer or in two layers. In the latter case, the second coating may contain the reducing agent or the reducing agent and the stabilizer.
