Abstract
1411181 Heat-processable colour photographic silver salt material MINNESOTA MINING AND Mfg CO 2 Jan 1973 [3 Jan 1972] 259/73 Heading G2C A heat-processable light-sensitive material, which becomes coloured when first exposed to light and then uniformly heated in the presence of a paraphenylene diamine developing agent, comprises a light-sensitive layer containing a normally lightstable organic silver salt, a source of mercuric ions, a source of halide ions and a colour coupler, the amounts of the components being so selected as to provide, for each equivalent of silver ions, 0.5-0.9 equivalent weight of each of the mercuric and halide ions, and at least one mole of the colour coupler. The material may comprise a separate second layer containing a reducing agent for silver ion e.g. a p-penylenediamine developing agent. A reducing agent for silver ion may be in the lightsensitive layer and may be the coupler (see Example 3). The light-sensitive layer may be on one surface of a transparent support having on its other surface a similar light-sensitive layer containing a different colour coupler (see Example 4). Negative images are produced in Examples 1 and 2 and a positive image in Example 3.
