Abstract
A UV-curable resin composition, which comprises blending urethane acrylate with tris(2-acryloxyethyl)isocyanurate, or with tris(2-acryloxyethyl)isocyanurate and with diacrylate, which composition has a low viscosity and a good drawing workability before curing and cures rapidly by ultraviolet radiation to give cured products having a high elastic modulus, a high elongation and a low water-absorption.
Claims8
A UV-curable resin composition which comprises blending 100 parts by weight of a urethane acrylate, which has been prepared by reacting 4,4'-dicyclohexylmethane diisocyanate with both ends of polytetramethylene glycol having a molecular weight of 650-1300 and then reacting the reaction product with a compound having a hydroxyl group and an acryloyl group in one molecule, with 10-140 parts by weight of a compound having the below-mentioned formula (1) or of a compound having the formula (1) and a compound having the below-mentioned formula (2):
