Abstract
A reactive component suitable for use in a radiation-curable composition, which comprises an acrylated epoxy-amine oligomer represented by the formula (I): C-B-[A-B]n-A-B-C wherein: n is from 2 to 500; each A is individually a unit derived from a diglycidyl ether; each B is individually a unit derived from a difunctional secondary amine or a monofunctional primary amine; and each C is individually a unit derived from a multifunctional acrylate monomer, radiation-curable compositions, such as inks, coatings and adhesives, comprising said reactive component and methods of making said reactive component.
Claims24
A UV or EB-curable reactive component, wherein said reactive component is the Michael addition reaction product of an amine-terminated copolymer and a multifunctional acrylate monomer, wherein said amine-terminated copolymer is the reaction product of a diglycidyl ether and an amine selected from a difunctional secondary amine or a monofunctional primary amine or a mixture thereof.
