摘要

The present invention provides a compound represented by the following formula (I):;;wherein
R1 and R2 each independently designates an alkyl group of 1 to 12 carbon atoms or a cycloalkyl group of 5 or 6 carbon atoms or R1 and R2 form together with the carbon atom to which they are attached a cycloaliphatic ring of 5 or 6 carbon atoms,Si* represents an organopolysiloxane residue bonded via a silicon atom of this residue to the oxygen shown in formula (I), or a silane group SiR4R5R6, wherein R4, R5 and R6 each independently designates an alkyl group of 1 to 12 carbon atoms, a cycloalkyl group of 5 or 6 carbon atoms or an aryl group of 6 to 10 carbon atoms, andR3 designates a hydrogen atom or a group represented by the following formula (II);;wherein
R7 and R8 each independently designates an alkyl group of 1 to 12 carbon atoms or a cycloalkyl group of 5 or 6 carbon atoms or R7 and R8 form together with the carbon atom to which they are attached a cycloaliphatic ring of 5 or 6 carbon atoms, andSi** represents an organopolysiloxane residue bonded via a silicon atom of this residue to the oxygen shown in formula (II), or a silane group SiR9R10R11, wherein R9, R10 and R11 each independently designates an alkyl group of 1 to 12 carbon atoms, a cycloalkyl group of 5 or 6 carbon atoms or an aryl group of 6 to 10 carbon atoms,a method to produce this compound and the use thereof as photoinitiator and/or photosensitizer.
