Abstract
Abstract Compositions containing an amine acrylate and another radiation curable composition. The amine acrylates are produced by the reaction of a diacrylate ester and an organic amine. The compositions are rapidly cured by electron beam radiation as well as other types of radiation as well as by light curing means; they are useful in the field of protective coatings.
