    摘要: The present invention relates to the use of acetophenone or benzophenone derivatives of the formula I where R is unsubstituted or substituted C1 to C3 alkyl, C6 to C10 aryl or aralkyl having from 6 to 10 carbon atoms in the aryl moiety and from 1 to 6 carbon atoms in the alkyl moiety as copolymerizable photoinitiators. The invention further relates to copolymers containing acetophenone or benzophenone derivatives of the formula I in copolymerized form, to processes for preparing said copolymers, and to the use of said copolymers in UV crosslinkable compositions.
