ABSTRACT:
Polymeric dyes having pendent chromophore groups which are selected from azo, tricyanovinyl, anthraquinone, methine, and indoaniline groups fall into two classes, [A] condensation polymers, and [B] polymers derived from copolymerized ethylenically-unsaturated monomers, the dyes being capable of undergoing thermoplastic deformation by a focused laser beam when in a layer of thickness in the range of 0.1 to 100 micrometers and having an absorptivity in the range of 10 to 250 Lg.sup.-1 cm.sup.-1. They are film-forming, thermally- and light-stable, and solvent-coatable. These compounds are useful as coloring and light-absorbing agents, particularly as the light-absorbing agents in thin optical recording layers.
