The invention relates to the field of the protection of security documents such as for example banknotes and identity documents against counterfeit and illegal reproduction. In particular, the present invention provides methods for producing optical effect layers exhibiting one or more indicia on a substrate, said method comprising a step of exposing a coating layer comprising non-spherical magnetic or magnetizable pigment particles to a magnetic field of a magnetic-field generating device so as to orient at least a part of the magnetic or magnetizable pigment particles; a step of applying a top coating composition on top of the coating layer and in the form of one or more indicia, and a step of at least partially curing the coating layer and the one or more indicia with a curing unit.

A method of uniformly applying multicolor paint which comprises two or more paints of different colors in discrete domains. The method includes applying the multicolor paint to a paint roller cover and rolling the paint roller cover on a surface to form a painted surface. The paint roller cover comprises a foam having a surface extending between a first edge and a second edge and a groove on the surface wherein a portion of the groove is positioned at an angle relative to an edge of the foam and has a groove depth of 1 to 15 millimeters and an average cell size in the range of about 0.03 to about 0.5 cm, wherein the average cell size of the foam is within 25% of the average domain size in the multicolor paint.

This patent discloses an aluminum alloy hub polishing color register process, specifically comprising the following steps of: polishing a blank, pre-treating, spraying transparent powder 1, curing, placing a hard protector, spraying a colored paint, curing, polishing a color register boundary line off line, pre-treating, spraying transparent powder 2, curing and discharging. The process solves the problems that the polished surface is easily scratched in the color register boundary treatment process and that the treatment efficiency is relatively low in the traditional polished color register products, improves the yield and production efficiency of polished color register products and increases the additional values of the products.

This disclosure describes substrate(s) having a three-dimensional (3D) feature formed thereon and methods of forming the features. One method involves applying a first layer of UV-curable material on a surface of the glass container around a circumference of the container and curing the first layer of UV-curable material to produce a first cured material layer that forms at least a portion of a first 3D feature. The method further comprises applying a second layer of UV-curable material on the surface of the glass container, spaced apart from the first 3D feature, around the circumference of the container, and curing the second layer of UV-curable material to produce a second cured material layer that forms at least a portion of a second 3D feature. The portion of the glass container between the first and second 3D features has a circumference less than that of the first or second 3D features.

The invention relates to the field of the protection of security documents such as for example banknotes and identity documents against counterfeit and illegal reproduction. In particular, the present invention provides security documents and decorative articles comprising one or more optical effect layers (OELs) and methods for producing said OELs, said OELs comprising magnetically oriented platelet-shaped magnetic or magnetizable pigment particles in an at least partially cured coating layer (x40)

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.

Described herein are coating systems for preparing multi-layered finishes, multi-layered finish coated substrates, and methods of applying multi-layered finishes to substrates. A coating system for preparing the multi-layered finishes includes a base coating component and a clear coating component comprising non-lightfast colorant particles having a color intensity. The color intensity of the colorant particles decreases upon exposure to light.

A multilayer coating film includes a lower coating film 5 containing a colorant, and an upper coating film 6. If the upper coating film 6 has a refractive index n1 of greater than or equal to 1.2 and less than or equal to 1.5, the ratio n1/n2 of the refractive index n1 of this upper coating film 6 to the refractive index n2 of the lower coating film 5 is set to be greater than or equal to 0.67 and less than or equal to 1. If the upper coating film has a refractive index n1 of greater than or equal to 1.6 and less than or equal to 3.0, the refractive index ratio n1/n2 is set to be greater than 1 and less than or equal to 1.67.

A method for painting a skin component of a vehicle includes conveying the skin component along a conveying direction. The method further includes controlling first and second painting robots by a control installation such that a first spraying tool of the first painting robot applies a first paint of a first color in a first sub-region and a second spraying tool of the second painting robot applies a second paint of a second color in a second sub-region, where in an overlap region within which the first sub-region overlaps the second sub-region, the first paint is applied over the second paint such that a quantity of the first paint is kept constant perpendicular to a painting direction and is reduced along the painting direction such that a color gradient from the first color to the second color is formed in the overlap region.
