Abstract

Organosilicon compounds with a siloxane portion and groups of the general formula --OR'OCH.dbd.CHR'' (i) linked via an Si--O--C bond, wherein R' is a divalent hydrocarbon radical or a group --R.degree.--(OR.degree.).sub.n --, wherein R.degree. is alkylene and n is from 1 to 12, R'' is H or alkyl are useful in radiation curable compositions, in which they are mixed with an initiator. The compositions are particularly useful in UV radiation curable relase coatings.
