Abstract
Titanocenes with .pi.-cyclopentadienyl ligands, in which one or two carbocyclic or heterocyclic aromatic rings are bonded to the metal, the aromatic rings being substituted in at least one of the two ortho-positions relative to the metal-carbon bonds by CF.sub.2 Z (Z=F or substituted or unsubstituted alkyl), are suitable as photoinitiators for the photopolymerization of ethylenically unsaturated compounds. They are distinguished by a high radiation sensitivity, stability to air and thermal effects, and high effectiveness in the range from UV light to visible light.
