Abstract (en)
[origin: EP0810468A1] A photothermographic recording material comprising a support; a photo-addressable thermally developable element comprising a substantially light-insensitive organic silver salt, photosensitive silver halide in catalytic association with the substantially light-insensitive organic silver salt spectrally sensitized to the infrared region of the electromagnetic spectrum and a binder; and in a hydrophobic layer an antihalation dye according to the general formula (I): <CHEM> wherein R<1> and R<15> independently represent an alkyl group or an alkyl group substituted with at least one fluorine, chlorine, bromine or an alkoxy-, aryloxy- or ester-group; R<2>, R<3>, R<16> and R<17> independently represent an alkyl group; R<4>, R<5>, R<6>, R<7>, R<18>, R<19>, R<20> and R<21> independently represent hydrogen, chlorine, bromine, fluorine or a keto-, sulfo-, carboxy-, ester-, sulfonamide-, substituted sulfonamide-, amide-, substituted amide-, dialkylamino-, nitro-, cyano-, alkyl-, substituted alkyl-, alkenyl-, substituted alkenyl-, aryl-, substituted aryl-, alkoxy-, substituted alkoxy-, aryloxy- or substituted aryloxy-group, which groups may be substituted; or each of R<4> together with R<5>, R<5> together with R<6>, R<6> together with R<7>, R<18> together with R<19>, R<19> together with R<20> or R<20> together with R<21> may independently constitute the atoms necessary to complete a benzene ring which may be substituted; R<8>, R<9>, R<10> and R<11> independently represent hydrogen, an alkyl group or each of R<1> together with R<8>, R<8> together with R<9>, R<9> together with R<10>, R<10> together with R<11> or R<11> together with R<15> may independently constitute the atoms necessary to complete a 5-atom or 6-atom carbocylic or heterocyclic ring which may be substituted; R<12>, R<13> and R<14> independently represent hydrogen, chlorine, bromine or fluorine; and A<-> is a fluorinated alkyl or aryl anion in which the degree of fluorination is greater than 70%; a production process therefor and a photothermographic recording process therefor.
