COMPOSITE FINE PARTICLE, METHOD FOR PRODUCING THE SAME, COATING COMPOSITION CONTAINING THE COMPOSITE FINE PARTICLE, AND OPTICAL FILM

摘要

Disclosed is a composite fine particle having adequate adhesion and dispersion stability at the same time, while exhibiting excellent curability. Also disclosed is a simple method for producing such a composite fine particle. Specifically disclosed is a composite fine particle comprising an inorganic core particle and an organic polymer bonded to at least a part of the surface of the core particle. The organic polymer has an ethylenically unsaturated group in a side chain. The ethylenically unsaturated group is preferably bound to the main chain of the organic polymer through a urethane bond. In addition, the organic polymer is preferably an acrylic polymer.
