Abstract
Ethylenically unsaturated polymerisable compounds can be cured with daylight or with light sources equivalent to daylight by using as hardener a photoinitiator of formula I ##STR1## wherein R.sub.1 is C.sub.1 -C.sub.12 alkyl, cyclopentyl, cyclohexyl, unsubstituted phenyl, naphthyl or biphenyl, PA1 R.sub.2 and R.sub.3 are each independently of the other C.sub.1 -C.sub.12 alkyl, PA1 R.sub.4 is hydrogen or C.sub.1 -C.sub.12 alkyl, and PA1 R.sub.5 is hydrogen or methyl.
