ABSTRACT:
Disclosed are novel colorant compounds which contain one or more ethylenically-unsaturated (vinyl), photopolymerizable radicals which may be copolymewrized (or cured) with ethylenically-unsaturated monomers to produce colored compositions such as colored acrylic coatings and polymers, e.g., coatings and polymers produced from acrylate and methacrylate esters, colored polystyrenes, and similar colored polymeric materials derived from other ethylenically-unsaturated monomers. The present invention also pertains to processes for the preparation of certain of the photopolymerizable colorant compounds.
