Title
(EN) "NOVEL PHOTOINITIATORS"
(FR) NOUVEAUX PHOTO-INITIATEURS
Abstract
(EN) The present invention relates to novel photoinitiators having improved performances and to their use in photopolymerization compositions. The invention also relates to a process for the photopolymerization of compositions comprising said photoinitiators as well as their use in articles of manufacture, including printed, coated, and fabricated assemblies.
