New Coinitiator-free Benzophenone Derived Photoinitiator

Radiation curing is a well established and highly efficient method for crosslinking of coatings, printing inks etc.' Photoinitiators 23 the key component in such systems have a great influence on storage life, curing rate and curing depth, but also on double bond conversion (DBC) and surface cure. Among the large group of P1 structures, benzophenones are one of the widespread used Pis due to their low costs, universal applicability and good reactivity.
