A method may be provided for manufacturing coated panels of the type including at least a substrate and a top layer with a motif. The top layer may be provided on the substrate. The method may involve providing a synthetic material layer on the substrate. A relief may be provided on the surface of said synthetic material layer provided on the substrate. The relief may include a pattern of recesses. The pattern may be at least partially determined by at least one print that is applied by inkjet printing. The relief may be obtained by printing a mask directly on or in the synthetic material layer. After providing the mask, the synthetic material layer may be cured. The mask may provide for selective curing of the synthetic material layer, such that the synthetic material layer is not solidified or solidified at a lesser extent in correspondence of the mask. The not solidified or less solidified portions of the synthetic material layer may be removed by performing a material-removing treatment on the synthetic material layer thereby obtaining the relief.

According to examples, a substrate may be moved through a magnetic field, in which the substrate includes a fluid carrier containing magnetically-orientable flakes. The magnetic field may influence the magnetically-orientable flakes to be respectively oriented in one of multiple orientations. In addition, during movement of the substrate through the magnetic field, radiation may be applied onto a plurality of selected portions of the fluid carrier through at least one opening in a mask to cure the fluid carrier at the plurality of selected portions and fix the magnetically-orientable flakes in the plurality of selected portions at the respective angular orientations as influenced by the magnetic field.

A coating composition includes a binder component (A), a flake-like aluminum pigment (B) having an average particle diameter (d50) of 18 μm to 25 μm, and a flake-like pigment (C) being a flake-like pigment other than flake-like aluminum pigments and having an average particle diameter (d50) of 8 μm to 30 μm. A content of the flake-like aluminum pigment (B) is 10 parts by mass to 50 parts by mass and a content of the flake-like pigment (C) is 0.5 parts by mass to 10 parts by mass, based on 100 parts by mass of the binder component (A). A content ratio (B)/(C) of the flake-like aluminum pigment (B) to the flake-like pigment (C) is 2/1 to 50/1 in terms of a solid content mass ratio.

A workpiece composed of acrylic material can be modified to produce a highly visual and aesthetic prismatic effect in which white light entering the workpiece can exit the workpiece in separate colors and sets. By applying dichroic paint and primer to precision cuts made into one of the planar surfaces of the workpiece, preferably filling in the spaces with a resin epoxy and then preferably sanding the surface, many more colors can be generated by the white light exiting the workpiece.

The present invention relates to the field of magnetic assemblies and processes for producing optical effect layers (OELs) comprising magnetically oriented non-spherical magnetic or magnetizable pigment particles on a substrate. In particular, the present invention relates to magnetic assemblies processes for producing said OELs as anti-counterfeit means on security documents or security articles or for decorative purposes.

A method may be provided for manufacturing a panel that may include a substrate and a top layer provided on the substrate. The top layer may have a printed motif and a translucent or transparent synthetic material layer provided above the printed motif. The panel may have a structure or relief at the surface. The method may involve milling profiles into the substrate to obtain mechanical coupling means for coupling together two of the panels. The structure or relief and/or the printed motif may be realized after milling the profiles into the substrate.

A method for producing a labeled printed circuit board, as well as a labeled electric printed circuit board. In order to provide a method for producing a labeled printed circuit board that is particularly fast and energy-conserving and does not require any systems with high procurement and operating costs, initially a substrate with conductor tracks is supplied, which is then coated with a functional lacquer layer on at least one surface. A labeling of the substrate in different color shades of the functional lacquer layer is also carried out.

The present invention relates to the field of magnetic assemblies and processes for producing optical effect layers (OELs) comprising magnetically oriented non-spherical oblate magnetic or magnetizable pigment particles on a substrate. In particular, the present invention relates to magnetic assemblies processes for producing said OELs as anti-counterfeit means on security documents or security articles or for decorative purposes.

An optical article printed on a substrate may include an organic binder; and a plurality of reflective magnetic platelets provided in the organic binder, wherein the plurality of reflective magnetic platelets are substantially aligned in accordance with at least part of a surface of revolution, and wherein the plurality of reflective magnetic platelets are aligned to cause a first reflective effect of the optical article when the substrate is rotated around a first axis and to cause a second reflective effect of the optical article when the substrate is rotated around a second axis, wherein the first reflective effect is different from the second reflective effect.

According to examples, an article may include a base layer that extends along a first dimension and a second dimension, in which the second dimension is orthogonal to the first dimension. The article may also include reflective ribbons provided on an upper surface of the base layer, in which the reflective ribbons positioned along a common plane extending in the second dimension have dihedral angles that change as a function of distance across the common plane.
