SINGLE HOLLOW PARTICLE, METHOD FOR PRODUCING THE SAME, RESIN COMPOSITION AND LIGHT DIFFUSION PLATE

摘要

PROBLEM TO BE SOLVED: To provide a single hollow particle having excellent light diffusion property.;SOLUTION: The single hollow particle comprises a vacancy, an inner polymer layer and an outer polymer layer in this order from the center to the outside, wherein the inner polymer layer comprises a (meth)acrylic ester-styrenic copolymer having a weight average molecular weight in a range of 50,000-400,000 as measured by GPC and containing 30 wt.% of a styrene component, and the outer polymer layer comprises a copolymer derived from a hydrophobic monomer mixture of 10-50 wt.% of a crosslinkable vinylic monomer and 90-50 wt.% of a styrenic monomer.;COPYRIGHT: (C)2009,JPO&INPIT
