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

摘要

PROBLEM TO BE SOLVED: To provide composite fine particles excellent in curability and having adequate adhesivity and dispersion stability in combination, and a simple method for producing such a composite fine particle.

SOLUTION: The composite fine particles comprise inorganic core particles and an organic polymer bonded to at least a part of the surface of the core particles. The organic polymer has an ethylenically unsaturated group in its side chain. The ethylenically unsaturated group is bound to the main chain of the organic polymer through a urethane bond. The organic polymer is preferably an acrylic polymer.
