Abstract
Abstract Compounds of the formula I, II or III <IMAGE> I <IMAGE> II <IMAGE> III in which Ar is a sulfur-containing aromatic radical, R1 and R2 are a monovalent hydrocarbon radical which is substituted or unsubstituted or R1 and R2 together form alkylene, oxaalkylene or azaalkylene, R3 is a direct bond or a divalent hydrocarbon radical, X is a monovalent amino group and X' is a divalent amino or diamino group, are excellent photoinitiators for the photocuring of colored, in particular pigmented, compositions containing an olefinically unsaturated, photopolymerizable binder.
