Abstract:
A polymerizable composition which consists essentially of(a) at least one ethylenically unsaturated monomer or oligomer, and(b) an initiator compound of formula I ##STR41##whereinn is 0,R.sub.1, R.sub.2 and R.sub.3 are each independently of one another NO.sub.2, cyano, --C(O)--R.sub.7, --OR.sub.8, unsubstituted C.sub.1 -C.sub.12 alkyl or phenyl, which is unsubstituted or substituted by C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, cyano, hydroxy, carboxy, C.sub.1 -C.sub.4 alkylamino or di(C.sub.1 -C.sub.4 alkyl)amino; orR.sub.2 and R.sub.3, together with the linking carbon atom, form a C.sub.5 -C.sub.7 cycloallyl radical;R.sub.7 is C.sub.1 -C.sub.8 alkyl or phenyl;R.sub.8 is C.sub.1 -C.sub.8 alkyl or C.sub.2 -C.sub.8 alkyl which is substituted by at least one hydroxy group; andR.sub.10 is C.sub.4 -C.sub.18 alkyl bound via a tertiary C-atom to the nitrogen atom, phenyl or C.sub.9 C.sub.11 phenyl-alkyl; orwhen n is 1;R.sub.11 is C.sub.1 -C.sub.12 alkyl; orR.sub.10 and R.sub.11 together for a C.sub.2 -C.sub.6 alkylene bridge which is unsubstituted or substituted with C.sub.1 -C.sub.4 alkyl; andR.sub.12 is hydrogen, unsubstituted C.sub.1 -C.sub.4 alkyl or phenyl.
