US 6,319,652 B1 · Energy beam curable epoxy resin composition

Abstract

The energy beam curable epoxy resin composition comprising as essential components, (1) specific cationically polymerizing organic substance,(2) energybeam sensitive cation polymerization initiator, (3) cationically polymerizing organic substance except for the specific cationically polymerizing organic substance, described above, (4) radically polymerizing organic compound, and (5) energy beam sensitive radical polymerization initiator. The cured articles resulted from said resin composition, have superior properties and particularlly superior dimensional stability on humidity absorption. Therefore, a stereolithographic resin composition and a stereolithographic method are also provided.
