ABSTRACT:
A transparent cured film including organic fine particles having an ultraviolet absorbing group and an average particle diameter of 1 to 200 nm, the particles being dispersed in a matrix having an Si—O bond, and having a transmittance of visible light of 80% or more and a haze value of 10% or less. The coating composition can be produced, for example, from a coating composition containing (1) an alkoxysilane compound or polyalkoxysilane compound; (2) an aminosilane compound; (3) an epoxysilane compound; (4) a polymer ultraviolet absorber; (5) a curing catalyst; and (6) a solvent.
