| abstract |
Ethylenically unsaturated compositions such as acrylic and methacrylic acid esters, vinyl esters, vinyl halides, unsaturated amides such as acrylamide, vinyl aromatics such as styrene, and various aliphatic and aromatic polyesters containing any of the above or other modifying components such as maleic, fumaric, itaconic, citraconic and the like, are very effectively and rapidly cured with certain 5-halo-6-halomethyluracil photoinitiators. These curable systems have extensive utility in the surface coatings industry, particularly in regard to cured protective coatings. |
