UNSATURATED GROUP-CONTAINING URETHANE RESIN AND ACTINIC ENERGY RAY-CURING RESIN COMPOSITION CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an unsaturated group-containing urethane resin having sufficient curability and giving a cured film excellent in flexibility and elongation and to provide an actinic energy ray-curing resin composition containing the same.;SOLUTION: The unsaturated group-containing urethane resin is obtained by reacting a polycarbonate diol (a) with a diepoxy (meth)acrylate (b) having two hydroxyl groups and two ethylenically unsaturated double bonds in the molecule and a polyisocyanate (c). The actinic energy ray-curing resin composition is obtained by adding 0.1-15 pts.mass photopolymerization initiator to 100 pts.wt. above unsaturated group-containing urethane resin.;COPYRIGHT: (C)2008,JPO&INPIT
