RESIN COMPOSITION AND CROSSLINKED MICROPARTICLE DISPERSED CURABLE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a curable resin composition capable of simultaneously satisfying the three performances of low viscosity, low shrinkage, and rapid curability. SOLUTION: This composition is prepared by dispersing (A) crosslinked microparticles obtained by polymerizing (a) a radical-polymerizable ethylenically unsaturated compound and (b) a compound having at least three (meth)acryloyl groups in the molecule and having a mean primary particle diameter in the range of 10-1,000 nm in (B) a compound having at least one (meth)acryloyl group on the molecule.
