초록 ▼

The present invention relates to a resin composition for optical molding which comprises (a) an actinic radical-curable and cationically polymerizable organic substance and (b) an actinic radiation-sensitive initiator for cationic polymerization. This composition can be cured without being affected

대표청구항 ▼

A resin composition for optical molding which comprises 50-90 parts by weight of (a) an actinic radiation-curable and cationically polymerizable organic substance containing at least 40% by weight of an epoxy resin having at least two epoxy groups in its molecule and at least 30% by weight of a vinyl ether resin having at least two vinyl groups in its molecule; (b) an actinic radiation-sensitive initiator for cationic polymerization; (c) 10-50 parts by weight of an actinic radiation-curable and radical-polymerizable organic substance at least 50% by weight of which is composed of a compound having at least three unsaturated double bonds in its molecule; and (d) an actinic radiation-sensitive initiator for radical polymerization the sum total of (a) and (c) being 100 parts by weight.
