Abstract
Abstract Compounds of the formula I, II or III ##STR1## in which Ar and Ar' are an oxygen-containing aromatic radical, R 1 and R 2 are a monovalent hydrocarbon radical which is substituted or unsubstituted, or R 1 and R 2 together form alkylene, oxaalkylene or azaalkylene, R 3 is a direct bond or a divalent hydrocarbon radical, X and X' are a monovalent amino group and Y is a divalent amino or diamino group, are excellent photoinitiators for the photocuring of colored, especially pigmented, compositions containing an olefinically unsaturated, photopolymerizable binder.
