Abstract
Abstract Amine acrylates are produced by the reaction of a diacrylate ester and an organic amine. The amine acrylates are rapidly cured by electron beam radiation as well as other types of radiation as well as by light curing means. These compounds and coating compositions containing them are highly useful in the field of protective coatings. Illustratively, the diacrylate ester of diethylene glycol is reacted with piperazine to produce piperazine diacrylate.
