A carbonate compound having ethylenically unsaturated and acetylenically unsaturated functions are disclosed. The compound is represented by the formula: ##STR1## wherein, A is the residue of a hydroxy group-containing, ethylenically unsaturated monomer with removal of the hydroxyl group, R.sup.1 and R.sup.2 are independently a hydrogen atom or a C.sub.1 -C.sub.20 alkyl.
A curable resin composition comprising (a) an acrylic, polyester, epoxy or polyol resin having a plurality of alkynyl groups, (b) an organohydrogenpolysiloxane, and (c) an amount of platinum catalyst effective to catalyze the cross link reaction between (a) and (b). The composition is useful for coating and molding purposes and gives a cured product having excellent acid resistance, water resistance and other properties.
