The invention relates to a process for roughening metal surfaces to improve adhesion of layers which are thermally sprayed thereon, in that in a first process step recesses or depressions () are introduced into the surface in a material-detaching or material-removing treatment so that the protruding metal of the surface forms raised microstructures (), in particular projections, ridges, protuberances or bumps, these microstructures being reworked in at least a second process step by shaping and/or breaking so that a significant proportion of the structures form undercuts () in relation to the surface.

Surface conditioning for thermal spray layers

A radiation-curable composite layered sheet or film comprising at least one substrate layer and one outer layer, said outer layer being composed of a radiation-curable composition having a glass transition temperature of more than 40&#xb0; C.

Radiation-curable composite layered sheet or film

Self-coating or self-layering lacquer systems from at least two different resins, oligomers, or polymers, which are emulsifiable or dispersible in water, have different surface tensions, and form self-layering phases. After the application, the phases separate into the components of the formulation.

Coating composition for forming self-layering or self-coating lacquer systems

A radiation-curable composite layered sheet or film comprising at least one substrate layer and one outer layer, said outer layer being composed of a radiation-curable composition having a glass transition temperature of more than 40&deg; C.

The invention relates to a process for applying coating films to three-dimensionally curved substrates, and to a process for producing coating films. In order to apply the coating film, which has at least a coating layer and an adhesive layer, the radiation-curable coating layer of the coating film is partially cured so as to be free from tack before being applied to the substrate. Following application, the coating film is subjected to electromagnetic radiation at below the wavelength of the visible spectrum and is fully cured. To produce a coating film, the coating layer is partially cured so as to be free from tack and in this state is stored until it is applied to a substrate. The coating layer can be attached at least indirectly to a smooth support base in-conjunction with an adhesive layer. The coating layer and/or the coating film can be detached from a roller in applying the coating film to a substrate.

Coating film for coating on a three-dimensionally curved substrate

The invention relates to a pigment with color dependent on the viewing angle, which has been obtained by three-dimensional crosslinking of oriented substances of liquid-crystalline structure having a chiral phase. In order to stabilize the color of such a pigment at elevated temperatures, crosslinking is carried out in the presence of at least one additional, color-neutral compound comprising at least two crosslinkable double bonds.

The invention relates to platelet-shaped interference pigments for effect paints for painting objects of daily use, especially vehicle bodies, with the interference pigments including liquid crystal polymers (LCP) with main and/or side groups&mdash;mesogens&mdash;which are arranged at least approximately chirally-nematically or the like. In order to be able to paint different colored backgrounds in a covering fashion using the transparent interference pigments, the interference pigments are built up in several layers and also have at least one and preferably two interfering layer(s) of liquid crystal polymers and even of a single, preferably centrally located, light-absorbent layer, with the light-absorbent layer absorbing at least a portion of the visible light spectrum. Advantageously the light-absorbent layer can absorb light in the entire visible light spectrum, in other words appear black. It is also possible for it to be made light-absorbent within those partial areas of the visible light spectrum that lie outside one of the colors of the interference pigments. A method is also disclosed for manufacturing the multilayer interference pigments.

The invention relates to a coating comprising a photochromic material, its production and its use. The photochromic material of the coating has an optically reversible photochromic effect, wherein the switching threshold is disposed outside of or in the boundary region of the visible range of the spectrum. According to the invention, the photochromic material is coated with an influencing material, so that the switching threshold of the coated photochromic material is shifted towards wavelengths longer than the switching threshold of the uncoated photochromic material.

The invention relates to platelet-shaped interference pigments for effect paints for painting objects of daily use, especially vehicle bodies, with the interference pigments including liquid crystal polymers (LCP) with main and/or side groups--mesogens--which are arranged at least approximately chirally-nematically or the like. In order to be able to paint different colored backgrounds in a covering fashion using the transparent interference pigments, the interference pigments are built up in several layers and also have at least one and preferably two interfering layer(s) of liquid crystal polymers and even of a single, preferably centrally located, light-absorbent layer, with the light-absorbent layer absorbing at least a portion of the visible light spectrum.

The invention relates to a method for painting an object during a creative shaping process, for example an injection-molding, extrusion-molding, or back-foaming method with a paint film, as well as a paint film for working the method. In the method, a paint film is placed in an open mold that internally has the original shape of the part. The mold is closed and filled with a starting material, with the starting material curing and/or bonding and/or reacting inside the mold to at least shape the object. To simplify the method, the paint in the paint layer of the paint film is partially cured and/or partially crosslinked before the starting material is added, without adhesive, and is cured only during and/or after the starting material is placed in the mold.

A process for preparing a phosphor layer of a cathode ray tube. To prepare a phosphor layer located on the display screen rear side of the cathode ray tube, the display screen rear side is first coated with an electrically conductive electrode layer consisting of electrically conductive polymers; a solution containing the phosphors or their precursors as well as a solution containing an electrolyte are deposited on the electrode layer; an electric field is applied between the electrode layer and the solution; and the phosphors are electrophoretically deposited on the electrode layer to form the phosphor layer. Since polymers with an evaporation temperature below the destruction temperature of the phosphors are selected, the electrode layer can subsequently be removed by evaporating the polymers.

The invention relates to an effect paint for objects to be painted, as well as to a process for making the effect paint, wherein the effect paint comprises pigments. The pigments, produced by fragmenting a wiped and cross-linked film, are added to a starting paint of a paint coat of the object and result in a color effect which depends on the viewing angle, and are also provided with a marking used to recognize and characterize the object.
