    摘要: A photothermographic recording material comprising a support and a photo-addressable thermally developable element, the photo-addressable thermally developable element containing a mixture of a substantially light-insensitive silver salt of a monocarboxylic acid and a substantially light-insensitive compound exclusive of silver succinate represented by formula (I): AgOOC—R1—COOAg wherein R1 is a straight chain saturated or unsaturated hydrocarbon group with two or three carbon atoms, optionally substituted with one or more of ═O, ═S, ═CR2R3, an alkyl group, an aryl group, an amino group, a substituted amino group, a cycloalkyl group, a hydroxy group, a thiol group, an alkyl sulphone group, an aryl sulphone group, an alkoxy group, an acyloxy group, a thioalkyl group, a thioaryl, a carbamic ester group, a halogen atom or a —(C═O)R4 group; wherein if R1 is substituted with two substituents selected from the group consisting of alkyl, thioalkyl, substituted amino and alkoxy groups the two substituents may jointly comprise the atoms necessary to complete a carbocyclic or heterocyclic ring; R2 and R3 are independently hydrogen or an alkyl, substituted alkyl, hydroxy or thiol; R4 is a hydroxy, —OAg, alkoxy, alkyl or —NHR6 group; R6 is hydrogen or an alkyl group; an organic reducing agent for the mixture of substantially light-insensitive organic silver salts in thermal working relationship therewith, a photosensitive silver halide in catalytic association with said mixture of substantially light-insensitive organic silver salts, and a binder; a photothermographic recording process therewith.

    摘要: In a light-sensitive material for tanning development containing unhardened or only slightly hardened gelatin silver halide emulsion layers, the silver content required to obtain maximum density is reduced by incorporating carbon black pretreated with water-miscible compounds which have a higher affinity for carbon black than gelatin. Suitable treatment may be provided by at least two of the following: poly-n-vinyl lactams, polyalkylene oxide derivatives, water-miscible compounds containing at least two OH groups, and polyalkylene oxides with a molecular weight of at least 400.
