Abstract: Provided herein is a process for the preparation of multilayered composite materials, and also multilayered composite materials which can be obtained according to this process.

Abstract: A process is disclosed for the preparation of multilayered composite materials comprising, as components: (A) a backing material, (B) optionally at least one tie layer and (C) a polymer layer, wherein a polymer layer (C) is formed using a mold, optionally at least one organic adhesive is applied all over or partially to backing material (A) and/or to polymer layer (C) and then polymer layer (C) is bonded with backing material (A) in point, strip or two-dimensional fashion, polymer layer (C) and/or at least one tie layer (B) being prepared from aqueous polymer dispersions which comprise at least one crosslinking agent C and from 0.1 to 5% by weight of at least one solvent selected from dipropylene glycol dimethyl ether and/or 1,2-propanediol diacetate.

Abstract: The present invention provides aqueous dispersions comprising a pigment (B) at least partially enveloped by polyurethane (A) and further comprising at least one polymerization inhibitor (C), said polyurethane (A) being obtainable by reaction of (a) 15% to 70% by weight of di- or polyisocyanate comprising on average from 1 to 10 allophanate groups and on average from 1 to 10 C—C double bonds per molecule, and optionally (b) 0% to 60% by weight of further di- or polyisocyanate, with (c) 5% to 50% by weight of compound having at least two isocyanate-reactive groups, weight % ages being based on total polyurethane (A).

Abstract: Process for producing multilayer composite structures, which comprises carrying out the following operations in succession: (a) use of power-modulated laser engraving to provide, to a female or male mold, a surface structure in the form of an image or of a pattern, where this has at least one element (D) which is not a geometric element, not a numeral, and not a letter, and where, within the surface structure, there are differences in screen angles, in depression depth, or in taper values, (b) optional molding of a female mold from the male mold, (c) spray-application of a plastics formulation onto the female mold, where the temperature of the female mold is in the range from 50 to 200° C., (d) solidification of the plastics formulation to give a film, (e) bonding the film to a substrate (A), (f) and removal of the mold, where the operations (e) and (f) can be carried out in any desired sequence.
