Disclosed is a reactive particulate resin which is characterized by each particle thereof having a core of three-dimensionally crosslinked resin having a degree of crosslinking from 0.05 to 2.0 mmol/g, and a shell formed thereon having a radical-polymerizable ethylenic unsaturated bond and is formed by polymerization of one or more polyfunctional monomers (A) and one or more non-aromatic radical-polymerizable monomers (B), the polyfunctional monomer (A) having in the molecule (a) at least one species of 1-monosubstituted and 1,1-disubstituted radical-polymerizable ethylenic unsaturated bonds and also (b) at least one of at least one species of 1,2-disubstituted, 1,1,2-trisubstituted, and 1,1,2,2-tetrasubstituted radical-polymerizable ethylenic unsaturated bonds.

Reactive particulate resin and method for its production

The invention provides a thermosetting resin composition for thermoforming which comprises 100 parts by weight of thermosetting resin, 100-400 parts by weight of inorganic filler, and 5-30 parts by weight of reactive particulate resin having on the surface reactive group(s) crosslinkable with said thermosetting resin.
