Abstract
A photopolymerisable system comprises an organic-inorganic compound with a metal and an organic unit having a organic photopolymerisable subunit capable of undergoing a polymerisation, a support matrix compound being polymer or capable of forming a polymer upon polymerisation, and a photoinitiator system adapted to initiate the polymerisation of the photopolymerisable subunits. The molecules of the organic-inorganic compound are distributed on a molecular level in the photopolymerisable system.
