Silsesquioxane compound having polymerizable functional group

摘要

A composition containing a silsesquioxane compound which has excellent compatibility not only with general polymerizable unsaturated compounds but also with highly polar polymerizable unsaturated compounds. The composition provides a coating film having excellent heat resistance and abrasion resistance. Specifically disclosed is a composition containing a silsesquioxane compound which has organic groups each directly bonded to a silicon atom, said composition containing a silsesquioxane compound being characterized in that at least one of the organic groups each directly bonded to a silicon atom is an organic group having a urethane boned and one (meth)acryloyloxy group.
