Abstract
The invention provides a cation polymerizable resin composition excellent in curing properties and corrosion resistance with less resin coloration and less cure shrinkage, which is a material suitable as a surface protective material for optical disk. Specifically, the cation polymerizable resin composition comprises an epoxy compound (A) as an essential ingredient represented by formula 1 wherein R1 and R2 each represent a saturated or unsaturated carbon atom, and R3 represents a hydrogen atom or a saturated or unsaturated carbon atom, a cation polymerizable compound (B) other than the epoxy compound represented by formula 1, a photo cation polymerization initiator (C) and a photo radical polymerization initiator (D).
