Abstract
In the case of an embossing lacquer based on a UV-polymerizable prepolymer composition containing at least one acrylate monomer, the prepolymer composition—in addition to the acrylate monomer—contains at least one thiol selected from the group: 3-Mercaptopropianates, mercaptoacetates, thioglycolates, and alkylthiols as well as potentially a surface-active anti-adhesive additive selected from the group of anionic surfactants, such as polyether siloxanes, fatty alcohol ethoxylates, such as polyoxyethylene (9) lauryl ethers, monofunctional alkyl (meth)acrylates, polysiloxane (meth)acrylates, perfluoroalkyl (meth)acrylates, and perfluoropolyether (meth)acrylates as well as a photoinitiator, as well as a method for imprinting substrate surfaces coated with an embossing lacquer.
