Abstract

The present disclosure relates to a method for transferring an embossed structure to a surface of a coating composition (B2a), which includes the steps (1-i) and (2-i) or (1-ii) and (2-ii) and also the steps (3) and optionally (4), where the steps (1-i) and (2-i) or (1-ii) and (2-ii) are performed using a composite (F1B1) which is employed as an embossing die (p2) of an embossing tool (P2) and which is composed of a substrate (F1) and of an at least partially embossed and at least partially cured coating (B1), and the coating composition (B1a) used for producing (B1) of the composite (F1B1) is a radiation-curable coating composition of defined constitution. Also described herein is a composite (F1B1).
