| 摘要 |
The invention relates to copolymerizable photoinitiators of the general formula I <IMAGE> (I) in which R1 and R2 are each H, C1-C6-alkyl or phenyl, R3 is H, C1-C6-alkyl, C1-C6-alkyl, C1-C6-alkanoyl or the group Z, R4 is H, halogen, C1-C12-alkyl, C1-C12-alkoxy, C1-C12-alkylthio or the group -X[(CH2-CH2-O)n-Z]m and X os O, S or N n is an integer from 0 to 4, m is the integer 1 for X=O and S or the integer 1 or 2 for X=N, Z is the group -CO-CR=CR'R'' with R, R', R'' each being H or CH3, always at least one of the R3 or R4 groups containing the group Z.
