| abstract | 1342523 Photographic light-sensitive heatdevelopable materials; thermographic materials EASTMAN KODAK CO 29 April 1971 [1 May 1970] 12182/71 Heading G2C Photographic light-sensitive, heat developable materials contain a light-sensitive silver compound such as a silver halide, a light-insensitive reducible metal compound such as silver behenate or a gold or mercury organic salt, a reducing agent for said metal compound such as hydroquinone or 2:2'-methylene bis(4-methyl-6-tertiary butyl-phenol), and an activator-toner which is (i) a 2-pyrazolin-5-one such as the 3-methyl or 3-phenyl derivatives, (ii) a cyclic imide of the formula:- where R 2 completes a ring and Z is H, OH, Hg, K, Na, Li or Au, such as succinimide or phthalimide, or (iii) a quinazolinone. After exposure to light, the materials are developed by heating to 70 to 250C to give a black image. |
