Claim:
1. A polyacrylate obtained by radical polymerization of at least one acrylate monomer (Ac) in the presence of a polymeric photoinitiator, said polymeric photoinitiator being a co-polymer of at least one monomer (A) with at least one monomer (B), wherein: monomer (A) is a photoinitiator monomer (A) of the formula (I): monomer (B) comprises at least two functional groups W wherein W 1 , W 2 , W 3 and W 4 are selected such that—in the co-polymerization of monomers (A) and (B)—W 1 reacts with W 3 to form a urethane, thiourethane, urea, thiourea, ester, ether, amide, carbonate, allophanate or biuret moiety, and W 2 reacts with W 4 to form a urethane, thiourethane, urea, thiourea, ester, ether, amide, carbonate, allophanate or biuret moiety.
