Coating compositions containing the oxygen sensitive diacrylate monomers 3-acrylyloxy-2,2-dimethylpropyl 3-acrylyloxy-2,2-dimethylpropionate, 1,3-bis(acrylyloxy)-2,2-dimethylpropane or mixtures thereof and further containing hiding pigment are cured by ionizing irradiation in the presence of a curing atmosphere containing from about 300 to about 1000 parts oxygen per million parts curing atmosphere. The resulting cured coating compositions are useful as protective coatings for many substrates.

Radiation cure of coating compositions containing diacrylate monomer and

This invention relates to radiation curable compositions having improved resistance to color bleaching, resistance to chalking and/or improved gloss retention. The compositions comprise ethylenically unsaturated diacrylate or an unsaturated polyester in admixture with a polymerized aminoalkyl alkoxysilane.

Radiation curable compositions containing organosilicon compounds

A composition comprising a vinyl resin and a mixture of acrylic compounds each having the formula: ##SPC1## Wherein n is from 0 to 10, or a mixture of acrylic compounds each having the formula: ##SPC2## Wherein n is from 0 to 10, may be coated on to a metal substrate and subjected to ionizing irradiation and used as a primer coating for numerous radiation-sensitive topcoats.

Method of coating a metal substrate and the coated substrate

Coating compositions comprising polyvinyl chloride are prepared by mixing a solution of polyvinyl chloride in an active solvent with an acrylic mixture and subjecting the mixture to ionizing irradiation. The cured films are hard, stain-resistant, heat-resistant, and mar-resistant.
