Abstract
The present invention provides a cation-polymerizable resin composition comprising (A) a multi-branched polyether polyol obtained from a ring-opening reaction of (a1) a hydroxyalkyloxetane and (a2) an epoxy compound having one epoxy group, (B) an alicyclic epoxy compound having at least two alicyclic epoxy groups, and (C) an acid generator, which may be used in various uses including, for example, an adhesive agent or tackiness agent for optical elements, various kinds of coating agents and the like.
Claims21
A cation-polymerizable resin composition comprising:
- (A) a multi-branched polyether polyol obtained from a ring-opening reaction consisting of (a1) a hydroxyalkyloxetane, (a2) an epoxy compound having one epoxy group, a polymerization initiator and an organic solvent, wherein (a1) and (a2) are mixed at the same time, and the epoxy compound (a2) is at least one selected from the group consisting of propylene oxide, 1-butene oxide, 1-pentene oxide and 1-hexene oxide;
- (B) an alicyclic epoxy compound having at least two alicyclic epoxy groups;
- and
- (C) an acid generator.
