International Classification:

C09B 116

US Classification:

552238, 4302811, 430 7, 552221, 552234, 552261, 552268

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.
