Description

ABSTRACT:
A photoreactive group-containing siloxane compound is obtained by subjecting a system comprising (a) a photoreactive group-containing alkoxysilane and (b) a hydrolyzable group end-capped dimethylsiloxane to hydrolytic condensation in the presence of a basic catalyst and with an amount of water greater than the amount necessary for hydrolytic condensation of all alkoxy groups. It forms on a substrate a coating having mar resistance, crack resistance, anti-staining effect, and marker ink wipe-off ability.
