| abstract | 1383399 Image receiving materials for transfer processes AGFA GEVAERT AG 10 Aug 1972 [12 Aug 1971] 37279/72 Heading G2C A material used as the receiving sheet for the imagewise transfer of a vaporizable reducing agent comprises a light-insensitive, reducible silver salt and a phthalimide of formula wherein R 1 and R 2 may be a saturated or unsaturated alkyl or alkoxy with 1-6 C atoms, cycloalkyl, cycloalkoxy, aralkyl, aralkoxy, hydroxy, aralkenyl or alkoxyarkenyl, and optionally a reducing agent which alone is insufficient to reduce the silver salt. The material may also contain a binder, a metal salt which improves image density as in Specification 1172425, a white pigment and 2, 6-di-t-butyl-pcresol. The material may be used with a light-sensitive material containing 4-methoxy-naphthol and erythrosin or 2-(p-chlorophenyl)-acetoacetonitrile, o-tolyl bignamidine and 1,3-diethyl-2-thio-5-[4- carboxymethoxy-cineamyidene] -barbituric acid wherein after imagewise exposure the non-exposed naphthol or acetoacetonitrile are transferred by heating to the silver material to produce a blueblack image. |
