Claim 15:
16. A method for transferring an embossed structure using an embossing tool, which comprises at least the steps
(1-i) applying a coating composition to at least a part of a surface of a substrate, to give a composite, and
(2-i) at least partially embossing the coating composition, applied at least partially to the surface of the substrate, by means of at least one embossing tool comprising at least one embossing die,
or
(1-ii) applying a coating composition to at least a part of an at least partially embossed surface of an embossing die of an embossing tool and
(2-ii) applying a substrate to at least a part of the surface of the coating composition, applied to the embossing die, to give a composite on the embossing die,, which comprises pretreating the at least one embossing die of the embossing tool, before the implementation of step (2-i) and before the implementation of step (1-ii), with at least one organic solvent and/or at least one reactive diluent, and, through step (2-i) and step (1-ii), transferring microstructures having a structure depth >30 μm as embossed structure onto the coating composition;, wherein the at least one organic solvent used for the pretreatment is selected from the group consisting of C1-C4 alcohols, and the at least one reactive diluent used for the pretreatment is selected from the group consisting of monofunctional, difunctional, trifunctional and polyfunctional (meth)acrylates and also mixtures thereof.
