An embossing lacquer containing radical polymerizable compounds (A) to (D) that have an overall aromatic content of at least 20 wt %: compound (A), which is a non-crosslinking compound and has an aromatic content of at least 40 wt %; compound (B), which is a crosslinking compound forming crosslinks via one or more aliphatic chain(s) each having a molecular weight of 200 to 2000 g/mol, wherein the content of the aliphatic chain(s) in compound (B) is at least 40 wt %; optionally compound (C), which is a crosslinking compound and has an aromatic content of at least 30 wt %; and optionally compound (D), which has a urethane group. A decorative article containing the cured embossing lacquer and a method of preparing the decorative article.

Elastic embossing lacquer having high optical dispersion

In the case of an embossing lacquer based on a UV-polymerizable prepolymer composition containing at least one acrylate monomer, the prepolymer composition&#x2014;in addition to the acrylate monomer&#x2014;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.

Embossing lacquer and method for embossing, and substrate surface coated with the embossing lacquer

With a prepolymer composition containing at least one mono or oligomer component with at least one polymerizable C&#x2014;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.
