A method for producing a multilayer body and a multilayer body, wherein the method includes: providing a single-layered or multi-layered substrate with a first surface and a second surface, providing one or more sensor films which each have at least one sensor area and have a first surface and a second surface facing away from the first surface, applying the one or more sensor films to the second surface of the substrate such that the first surface of the respective sensor film rests on the second surface of the substrate at least in areas, thermoforming a series of layers comprising the substrate and the one or more sensor films applied to the second surface of the substrate such that, during the thermoforming, on the first surface of the substrate a surface relief is formed which is determined by the shaping, of one or more of the one or more sensor films.

Aspects of the present invention relate to a resilient multilayer decorative surface covering and a method for producing a resilient multilayer decorative surface covering. The method comprises providing a substrate (36) and digitally embossing a coating on the substrate. Digitally embossing the coating comprises applying a plurality of plastisol or organosol layers (40a, 40b) so as to produce a coating having a three-dimensional surface relief, wherein at least one of the plurality of plastisol or organosol layers is structurally patterned.

A safety device designed to be provided in or on a substrate or in or on one or more layers applied to the substrate, comprising: a. a surface relief structure and b. a coating, wherein i. the surface relief structure is filled with the coating to form a flat surface, and wherein the coating has a refractive index greater than the refractive index of the surface relief structure, or ii. the coating forms all or part of the surface relief structure, wherein the surface relief structure of the coating is filled with one or more transparent lacquer layers to form a flat surface, wherein, for each alternative, the coating comprises particles of at least one metal oxide dispersed in a transparent lacquer, wherein the coating comprises 1 to 60 wt.-% metal oxide comprises, wherein the particles have a primary crystallite size of 1 to 100 nm, and wherein the concentration of the particles in the coating is high enough to induce a refractive index shift, so that the optical effect of the surface relief structure remains essentially unaffected or is even enhanced.

The present application belongs to the technical field of laser manufacturing, and relates to a surface morphology control method based on laser shock wave effect. In laser shock strengthening, different surface relief microstructure phenomena of different morphological characteristics appear on the material surface due to laser energy distribution defects. The method of the present application can realize the acquisition of different surface roughness. A pretest needs to be set, different parameters of porous pipes are used to generate bubbles of different volumes and concentrations in the water constraint layer, the laser energy distribution is guided, and the appropriate parameter range is determined. Further adjustment of laser energy, bubble volume and concentration can finally obtain different surface roughness on the material surface. In the absence of a mold, the present application realizes different surface roughness of the material in a non-contact manner, and has the advantages of high efficiency and wide adaptability.
