Mixtures of aromatic-aliphatic ketones as photoinitiators and photopolymerizable systems containing them |
摘要 |
Mixtures containing at least one hydroxyalkylphenone of the formula <IMAGE> wherein R1 is H, alkyl of 1-4 C atoms or chlorine, R2 is H or methyl, R3 is H or methyl, R4 is alkyl of 1-6 C atoms and R5 is alkyl of 1-6 C atoms, and at least one 2-alkylthioxanthone of the formula <IMAGE> wherein R6 is alkyl of 1-8 C atoms, have a considerably increased reactivity in initiating the photopolymerization of ethylenically unsaturated compounds. The polymers fully hardened using these initiator mixtures suffer only little yellowing.
