Title:
ACTINIC RADIATION-CURABLE COMPOSITION FOR CAST POLYMERIZATION AND PRODUCT OF CAST POLYMERIZATION
Document Type and Number:
WIPO Patent Application WO/1988/008434
Kind Code:
A1
Abstract:
An actinic radiation-curable composition for cast polymerization and products of cast polymerization are disclosed. The composition comprises: (A) 40 to 90 parts by weight of a urethane poly(meth)acrylate having two or more (meth)acryloyl groups per molecule; (B) 10 to 60 parts by weight of a vinyl monomer having a boiling point of 100°C or above and capable of undergoing radical polymerization; and (C) at least one of methyl phenylglyoxylate, 2-hydroxy-2-methyl-1-phenylpropan-1-one, hydroxycyclohexyl phenyl ketone13nd a photo initiator represented by general formula (I) (wherein R1 and R2 each represents phenyl, methoxy, ethoxy or isopropyloxy) in an amount of 0.005 to 5 parts by weight per 100 parts by weight of the sum of components (A) and (B). The cast polymerization product is obtained by radical polymerization of the composition using actinic radiation.
