Problems solved by technology

However, they generally have the disadvantage that they can only be used very limitedly as embossing stamps in the sub-micron range, and that the cross-linked polymer material does not fully harden sufficiently rapidly in the embossing process so that the embossing is reliable sex relatively low, so it does not appear to be possible to achieve defect-free self-replication of impressions in the embossing process using currently available embossing lacquers

Embodiment 1

[0045] Preparation of embossing paints according to the invention

[0046] 84% acryloylmorpholine (ACMO), 10% 2-Ethylhexylthioglykolat (2-Ethylhexylthioglykolat), 5% 2-hydroxy-2-methyl as photoinitiator by gravure printing -1-Phenyl-propan-1-one and 1% polysiloxane surfactant applied on a PET film with a thickness of 50 μm, where the pickup volume of the gravure roll 1.6ml / m 2 , which corresponds to a wet layer thickness (Nassschichtdicke) of about 0.8 μm, and was carried out at an orbital speed (Bahngeschwindigkeit) of 10 m / min using a nickel embossing tool with a raised embossing structure with a structure width of 5 μm and a structure height of 1 μm embossed. The pneumatic pressure at the counter roll (Gegenwalze) was 4 bar. UV polymerization was carried out by irradiation with a Hg-medium pressure vapor lamp at 100 W / cm.

Abstract

In the case of embossing paints based on UV-polymerizable prepolymer compositions comprising at least one acrylate monomer, said prepolymer composition comprising, in addition to acrylate monomers, at least one selected from Thiols from the group: 3-mercaptopropionates, thioglycolates, 2-mercaptoacetates and alkylthiols and optionally surface-active anti-adhesive additives selected from the group: non-ionic surface-active agents such as polyether siloxanes, fatty alcohol ethoxylates such as polyoxyethylene‑(9)‑lauryl ether, monofunctional alkyl‑(meth)acrylates, polysiloxane‑( Meth)acrylates, perfluoroalkyl-(meth)acrylates and perfluoropolyether-(meth)acrylates, and photoinitiators, and methods for embossing substrate surfaces coated with embossing lacquers .

Description

technical field [0001] The invention relates to embossing paints based on UV-polymerizable prepolymer compositions comprising at least one acrylate monomer And a method of embossing the surface of a substrate coated with an embossing varnish based on a UV polymerizable prepolymer composition comprising at least one acrylate monomer. Background technique [0002] Due to the rapid development of nanotechnology in recent years, the production of nanostructured components, where such nanostructured components are usually made from photopolymerizable prepolymer compositions, has become significantly more important in industrial manufacturing. Particularly in the field of decoration, product marketing and the surface modification of various materials such as films, extremely fine structures are increasingly used to achieve specific additional functions, such as decorative optical effects. For this purpose structures prefabricated by nanotechnology are used, which are produced fr...
