Abstract:
The present disclosure relates to a process for producing matt coatings on sheetlike substrates. The method includes providing an uncured lacquer layer of a UV radiation-curable liquid lacquer formulation F on a surface of the substrate to be coated. The method also includes irradiating the lacquer layer with UV radiation substantially in the wavelength range of 250 to 420 nm with a radiation dose which results in partial curing of the lacquer layer. The method further includes irradiating the partially cured lacquer layer with UV radiation in the wavelength range of 150 to
Abstract:
The invention relates to a novel stabilizer mixture comprising certain UV absorbers and specific (meth)acrylates, which are stable during storage and which are easily miscible with radiation curable coatings.
Abstract:
Aqueous polymer compositions and their use as coatings are disclosed. A composition includes at least one polyurethane (meth)acrylate A and at least one compound B having a molecular weight of below 1000 g/mol and having at least two ethylenically unsaturated double bonds per molecule. The polyurethane (meth)acrylates A include the following components: component A1 includes at least one polyisocyanate A1a and at least one diisocyanate A1b; component A2 includes at least one compound having at least one ethylenically unsaturated double bond, and at least one functional group F; component A3 includes at least one neutral polyol including at least one aliphatic, polymeric polyol A3a and at least one low molecular weight diol A3b; component A4 includes at least one compound having at least one ionic or ionizable group I′ and at least one functional group F′; and component A5 includes at least one poly-C2-C3 alkylene ether.
Abstract:
The present invention describes radiation-curable, water-dispersible polyurethane acrylates which feature good grain highlighting, their use, and the method for producing them.

Abstract:
Described are radiation-curable formulations which produce coatings having high adhesion to sheets and low contraction. Also described is use of the radiation-curable formulations, and processes for coating sheets by means of these formulations.
