Abstract
1324284 Light-sensitive; heat-developable photographic materials AGFA GEVAERT A G 26 April 1971 [29 April 1970] 11272/71 Heading G2C Lightsensitive, heat-developable photographic materials contain a non-light-sensitive silver salt (e.g. silver behenate), a light-sensitive heavy metal compound (e.g. a silver halide or salts of Hg or Au), and a reducing agent which is a pyrayolin-5-one, preferably having at least one hydrogen atom or a 4-aminophenylamino group in the 4-position. After exposure to light, the material is developed by heating to 60C. to 160C. to obtain a negative image. A positive image may be formed by heating the exposed material in contact with an image-receiving layer which contains a reagent which undergoes a colour forming reaction with unused pyrazolin-5-one transferred from the unexposed areas.
