The invention relates to a prepolymer composition containing at least one mono- or oligomer unit with at least one polymerizable C-C double bond and at least one multifunctional monomer unit, said multifunctional monomer unit being a multifunctional monomer unit with at least two thiol groups selected from the group consisting of: 3-mercaptopropionates, 3-mercaptoacetates, thioglycolates and alkyl thiols, that the mono- or oligomer unit with at least one polymerizable double bond is selected from the group consisting of acrylates, methyl acrylates, vinyl ethers, allyl ethers, propenyl ether, alkenes, dienes, unsaturated esters, allyl triazines, allyl isocyanates and N-vinyl amides and that at least one surface-active anti-adhesive additive selected from the group consisting of alkyl(meth)acrylates, polysiloxane (meth)acrylates, perfluoroalkyl(meth)acrylates, perfluoropolyether(meth)acrylates, alkylvinyl ethers, polysiloxane vinyl ethers, perfluoroalkyl vinyl ethers and perfluoropolyether vinyl ethers, as well as a photo-initiator are contained, and use thereof. |
