Abstract
The invention is a composition made by mixing a multifunctional acrylate with an aminofunctional silane and an ethylenically unsaturated acid to form a reaction product, optionally dissolved in a solvent, characterized in that the multifunctional acrylate has a molecular weight of from about 100 to about 3000. The composition can be coated on a substrate, then optionally exposed to moisture and treated to initiate a free radical reaction. The invention can be applied to a variety of substrates used in packaging applications. The reaction mixture can further be cured by heating in the presence of moisture. The free radical reaction can be initiated by electron beam irradiation, ultraviolet radiation, gamma radiation, and/or heat and chemical free radical initiators.
