FLAECHENFOERMIGES LASEROPTISCHES AUFZEICHNUNGSMATERIAL.

摘要

Flat laminated laser-optical recording material has an amorphous, thermally-modifiable, electroconductive recording layer, which contains dyestuff (I) and polymer (II) bound to one another through ionic bonds. (I) is anionic, pref. with carboxylate, phosphonate, O-phosphate, O-sulphate or sulphonate gps., esp. a phthalocyanine, porphin, tetraazaporphin, hemiporphyrazine or tetrathiolato metal complex deriv.. (II) is cationic, pref. with ammonium, imonium, sulphonium or phosphonium gps. and/or a positively charged bond system of several conjugated double bonds, esp. a pyrrole or thiophene homo- or copolymer or an aniline homopolymer.
