Carbonyl derivatives of 1-phenylindan suitable for use as polymerization photoinitiators, their preparation and use

摘要

New carbonyl derivatives of 1-phenylindan suitable for use as photoinitiators in the photopolymerization of compounds or mixtures of compounds containing ethylenic double bonds. The carbonyl derivatives of 1-phenylindan according to the present invention possess high efficiency as photoinitiators in terms both of the concentration used and the photopolymerization rate.
