Metallocenes and photopolymerisable composition containing same 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 in at least one of the two ortho-positions relative to the metal-carbon bonds, are suitable photoinitiators for the photopolymerisation of ethylenic- ally unsaturated substrates. They are distinguished by high sensiti- vity, stability to air and heat, and are very effective in the range from UV light to visible light.
