ABSTRACT:
Titanocenes with silylated .pi.-cyclopentadienyl ligands in which one or two carbo- or heterocyclic aromatic rings are bonded to the titanium, the aromatic rings being substituted by fluorine, --CF.sub.3, --C.sub.2 F.sub.5, --CF.sub.2 CL or --CF.sub.2 CH.sub.3 in at least one of the two ortho-positions relative to the metal-carbon bonds, are suitable as photoinitiators for the photopolymerization of ethylenically unsaturated substrates. They are distinguished by a high sensitivity, stability to air and the action of heat, and a high activity in the region of UV light to visible light. They are furthermore readily soluble in the photopolymerizable compositions.
