Abstract

With a prepolymer composition containing at least one mono or oligomer component with at least one polymerizable C—C double bond as well as at least one multifunctional monomer component, the multifunctional monomer component a multifunctional monomer component is contained with at least two thiol groups selected from the group: 3-Mercaptopropionates, 3-Mercaptoacetates, thioglycolates, and alkylthiols, wherein the mono or oligomer component with at least one polymerizable double bond is selected from the group acrylates, methyl acrylates, vinyl ethers, allyl ethers, propenyl ethers, alkenes, dienes, unsaturated esters, allyl triazines, allyl isocyanates, and N-vinyl amides, and wherein at least one surface-active anti-adhesive additive selected from the group alkyl (meth)acrylates, polysiloxane (meth)acrylates, perfluoroalkyl (meth)acrylates, perfluoropolyether (meth)acrylates, alkyl vinyl ethers, polysiloxane vinyl ethers, perfluoroalkyl vinyl ethers, and perfluoropolyether vinyl ethers, as well as a photoinitiator are contained, as well as the use thereof.
