Abstract

1512046 Heat-developable radiation sensitive colour silver halide material EASTMAN KODAK CO 14 July 1975 [12 July 1974] 29481/75 Heading G2C [Also in Division C4] A heat-developable radiation-sensitive material comprises a support and, in one or more layers on one side thereof, a photographic silver halide, a silver salt of a fatty acid having at least 10 carbon atoms, a phenolic leuco dye reducing agent for the fatty acid silver salt and a synthetic polymeric binder. The reducing agent may have the formula:- where R1 is halogen, 1-7C alkyl, 5-10C carbocyclic, 1-5C alkoxy or -CONR4R5; R4 and R5 are each H, 1-10C alkyl or 6-12C aryl; R2 is halogen, 1-7 C alkyl, 5-10C carbocyclic, 1-5C alkoxy, 2-6C alkoxycarbonyl or -CONR6R7 or with R3 completes a naphthalenic ring; R6 and R7 are each H, 1-10C alkyl or 6-12C aryl; R3 is H or with R2 completes a naphthalenic ring; and Q is a group which enables the reducing agent to be oxidizable to a quinone methide dye or azomethine dye. Specified phenolic leuco dye reducing agents are 2-(3, 5-di-tert-butyl-4-hydroxy-phenyl)-4, 5-diphenylimidazole, 2-(4-hydroxy -3, 5-dimethoxyphenyl) -4, 5-bis (p-methoxyphenyl) imidazole, bis- (3, 5-di-tert-butyl-4-hydroxyphenyl) phenylmethane, 2-(3-5-di-tert-butyl-4-hydroxyphenyl)-4-(2, 4, 6- trimethylphenyl)-5-phenylimidazole and 3, 3′- dicarbomethoxy-4, 4′-dihydroxy-5, 5′-dimethyl-4- dimethylamino-triphenylmethane. In Examples 3, 4 and 7 an image is formed in the support. In Example 5 an image is transferred to an imagereceiving layer containing a mordant using a solvent. In Example 8 the material comprises a transparent support bearing, in order, a mordanted imagereceiving layer, a titanium dioxide opacifying layer and the light-sensitive heat-developable layer, and a dye image is formed in the last-mentioned layer and transferred to the receiving layer on imagewise exposure to tungsten light and overall heating with a metal block. Alternatively the integral material may contain no opacifying layer in which case the sensitive layer is removed to reveal the transformed image. In another embodiment, not exemplified, the developed negative silver plus dye image is contacted in the presence of a solvent with an image-receiving layer containing a mordant capable of oxidizing the leuco dye to the dye, residual leuco dye being transferred to the receiving layer where it is oxidized to the dye, and the material optionally being integral.
