摘要:
Compositions polymerizable by ultraviolet irradiation which contain photopolymerizable monomers possessing at least one polymerizable carbon-carbon multiple bond and monoketals of the formula ##STR1## as photoinitiators. The compositions have a particularly long shelf life and show very little yellowing after curing by irradiation.
