In this paper, the photochemical properties of benzoyl derivatives, e.g. KI
P-100F and ESACURE TZT were studied using the N121 UV Curing Tester. It was
shown that their photochemical reactivity is higher; the photoactivation o
f triethanol amine(TEA) upon ESACURE TZT is greater, upon KIP-100F is unexp
ected; the sensitization of fluorescein upon KIP-100F is larger than upon E
SACURE TZT/TEA systems; the synergistic action of them is very effective; (
