A method for producing a multilayer composite comprising: (a) a surface structure in the form of an image or pattern having at least one element (D) different from geometric elements, numbers and letters; Preparing a female or male mold by power-modulated laser engraving, with varying raster angles, pore depths or tapering shapes within the surface structure, (b) optionally from male to female mold (C) spraying the plastic compound onto the female mold, wherein the female mold has a temperature in the range of 50-200 ° C. and (d) solidifying the plastic compound. (E) The step of bonding the coating to the substrate (A), (f) The step of removing the mold are sequentially performed, and the working steps (e) and (f) are optional. It can be carried out in the order of The process of the layer composite. |
