ABSTRACT:
Titanocenes containing .pi.-cyclopentadienyl ligands, in which one or two carbocyclic or heterocyclic aromatic rings are attached to the metal atom, said aromatic rings being substituted by fluorine in at least one of the two ortho-positions relative to the metal-carbon bonds, are suitable photoinitiators for the photopolymerization of ethylenically unsaturated substrates. They are distinguished by high sensitivity, stability to air and heat, and are very effective in the range from UV light to visible light.
