Title:
COMPOSITE POLYMER, THERMOSETTING COATING COMPOSITION, AND MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2007/026529
Kind Code:
A1
Abstract:
Disclosed is a composite polymer obtained by reacting (a) an elastomer having a carboxyl group with (b) a metal oxide fine particle having an epoxy ring-containing group on the surface. The composite polymer enables to obtain a thermoset product which is suitable for forming a primer layer having not only high transparency but also good adhesion to a hard coat layer while being excellent in abrasion resistance, heat resistance, weather resistance, dyability, impact resistance and the like. A molded article such as an optical article whose primer layer contains a thermoset product of the composite polymer has high transparency and excellent heat resistance.
