METHOD FOR VARNISHING SUBSTRATES AND VARNISHED SUBSTRATES Russian patent published in 2023 - IPC D21H19/82 B41M5/52 

Abstract RU 2810263 C2

FIELD: manufacturing printed products.

SUBSTANCE: invention concerns a method for manufacturing a varnished printed product. According to the method, a composition is applied to a substrate to form the first layer, which is a sealing layer, said composition containing at least one monomer, oligomer or prepolymer having at least one cross-linkable functional group. The first layer is then cured and overlaid, at least in places, by the second layer, the second layer having a closed surface in the sealed areas. The invention further relates to a printed product comprising a substrate, the first layer and the second layer, wherein the first layer and the second layer comprise an organic cross-linked varnish and have a closed surface, wherein the first layer is transparent and has a thickness of from 1 to 10 microns. The second layer is applied to at least areas of the first layer such that the first layer is located between the substrate and the second layer.

EFFECT: invention provides a varnishing method, in particular varnishing by inkjet printing of a substrate to produce coatings having a high surface quality regardless of the structure and characteristics of the surface, as well as creating a varnished printed product with a high surface quality.
