发明名称 Photopolymerisation processes and novel compounds therefor
摘要 A process for photopolymerizing a photopolymerizable compound having at least one ethylenically unsaturated double bond, comprises contacting said photopolymerizable compound with a photoactive oxide and irradiating it, wherein the photoactive oxide includes one or more moieties together with a moiety wherein there are at least 2 atoms between moiety I and moiety II in the additive and where X represents an oxygen or sulphur atom. Novel compounds which exhibit beneficial effects on cure in the presence of oxygen, which may be especially advantageous when LEDs are used, are also described.

主权项 1. A process for photopolymerising a photopolymerisable compound having at least one ethylenically unsaturated double bond, which comprises contacting said photopolymerisable compound with a photoactive oxide and irradiating it, wherein the photoactive oxide includes a moiety of the following formula wherein X represents an oxygen or sulphur atom; where R2, R3 and R4 independently represent C1-20 alkyl and R5 represents a hydrogen atom; and R8 is an optionally-substituted phenyl group.
