More Information
Summary:A radiation curable resin which is a reaction product of: having at least two (meth)acryloyl groups at both terminal ends of a molecular chain which is obtained by reaction of (1) a polyester polyol and/or polycarbonate polyol, (2) a diisocyanate, (3) a polyfunctional (meth)acrylate containing a hydroxyl group therein, and optionally (4) a compound having at least two active hydrogens in the molecule is disclosed. The resin has at least two (meth)acryloyl groups at a terminal end of the molecular chain. The molecular weight of the resin is 1,000 to 50,000, the urethane bonding concentration is not more than 3,000 equivalent/10 g and the (meth)acryloyl group concentration is 100 to 6,000 equivalent/10 g. A radiation curable resin composition containing the resin and a precoated metal using the composition are also disclosed.
