<P>PROBLEM TO BE SOLVED: To provide a transparent base on the surface of which a cured coat excellent in adhesion to the base and particularly suitable as a reflection preventing film is formed. <P>SOLUTION: The cured coat is formed on the surface of the transparent base by using as a curable material a composition which comprises 10-90 pts.wt. of a copolymer constituted by radically polymerizing 10-99 wt.% of a radically polymerizable compound having an alkoxysilyl group and 1-90 wt.% of a (meth)acryloyloxy compound on a total monomer basis, and 10-90 pts.wt. of a porous silica. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
