摘要：The invention relates to novel radiation-hardening compositions containing (A)linear organopolysiloxanes with (meth) acryloxy groups of general formula (I): R1aR3-aSiO(R2SiO)c[R2Si-Y-SiR2O(R2SiO)c]dSiR3-bR1b wherein R can be the same of different,and can mean a monovalent, optionally substituted hydrocarbon radical with 1 to 18carbon atoms per radical, which is free from terminal aliphatic carbon-carbon-multiplebonds, R1 is a radical of formula (II), wherein Z is a whole number ranging from 1 to 10, R2is a hydrogen atom or a methyl radical, R3 is a linear or branched alkylene radical with 1to 6 carbon atoms per radical and R4 stands for a linear or branched alkylene radical with1 to 6 carbon atoms per radical, Y is a bivalent organic radical which is free from terminalaliphatic carbon-carbon-multiple bonds, a is 0 or 1, b is 0 or 1, with the proviso that thesum a+b per molecule is 1 or 2, on average 1.3 or 1.9, c is a whole number ranging from 1to 1,000 and d is 0 or a whole number ranging from 1 to 10, and (B) photosensitizers.
