FIELD: material processing.

SUBSTANCE: invention relates to the field of production of embossed structures, which are used for giving material optical, bionic, and/or tactile properties and concerns a method for the transfer of an embossed structure to the coating surface, and combined material containing this coating. The method is proposed for the transfer of an embossed structure to part of the coating surface, using combined material of substrate (F1), and from at least partially embossed and at least partially cured coating (B1), wherein coating (B2) and coating (B1) of combined material (F1B1) have embossed structures mirror relatively to each other. In this case, the method includes at least steps (1) and (2), as well as, in necessary, (3). The invention also relates to combined material (B2B1F1), as well as the use of this combined material for the production of at least partially embossed coating (B2) in the form of free film or combined material (B2KF2) of substrate (F2), at least ne adhesive substance (K), and coating (B2).

EFFECT: invention provides for a method for the transfer of embossed structures to coatings, which makes it possible to transfer embossed structures, such as microstructures and/or nanostructures with sufficient accuracy of form copying, and makes it possible to make the most suitable for reuse matrix for embossing for transfer of embossed structures, or which can be implemented using such a matrix for embossing, as well as which makes it possible to provide large parts or parts with non-planar geometry, having such an embossed structure with coating, which has sufficient resistance to atmospheric impacts.
