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.

To deposit a photochromic substance 3 on a surface-forming portion 1 of an object; and, when light in an ultraviolet range 5 is projected onto the surface of the deposited photochromic substance 3 to change the color of the photochromic substance 3 by photochromism, cover the deposited photochromic substance 3 with a wavelength-cutoff agent 4 that blocks wavelengths in an ultraviolet spectrum contained in natural light and/or illumination light.

The apparatus and methods of the present disclosure relate to devices comprising spinning magnets driven by electric motors for use with printing or coating equipment. These devices and methods are for orienting magnetic or magnetisable pigment particles in an unhardened coating composition on a substrate. Specifically, these devices and methods are for producing optical effect layers. The apparatus comprises a holder, onto which is mounted a motor and a permanent magnet assembly. The motor is configured to spin the permanent magnet assembly. The holder is configured to be removably fixed to a base of a rotating magnetic cylinder (RMC) or a flatbed printing unit.

A deposition device may deposit, on a substrate, a binder layer that includes a first set of magnetic flakes and a second set of magnetic flakes and may cause, when a temperature of the binder layer satisfies a temperature threshold (e.g., a Curie temperature of the first set of magnetic flakes), a magnetic field to be applied to the binder layer to cause the first set of magnetic flakes and the second set of magnetic flakes to be oriented according to the magnetic field. The deposition device may cause, when the temperature of the binder layer ceases to satisfy the temperature threshold, another magnetic field to be applied to the binder layer to cause only the second set of magnetic flakes to be oriented according to the other magnetic field.

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.

A roofing material composition and a method of applying that roofing material composition using specific angles to deflect infra-red rays and provide aesthetically nice finish is disclosed. The first coat of the roofing material is light in color and the second color may be a light or a dark color. The rough surface is prepared using specific filler, resin and paint to deflect infra-red rays and reduce heating inside a building.

A method for manufacturing a golf ball having a multi-layered pattern is provided. Firstly, a semi-finished product of the golf ball is provided and includes a ball-shaped body and a base layer covering an outer surface of the ball-shaped body. Then, the semi-finished product of the golf ball is rotated at a predetermined rotation speed, and a color paint is applied to the semi-finished product of the golf ball by spraying from each of an upper position, a middle position, and a lower position. The multi-layered pattern includes an upper-layer pattern area, a mid-layer pattern area, and a lower-layer pattern area that are different in color from each other.

An article includes a substrate and an optical effect coating disposed on the substrate. The optical effect coating includes particles of a magnetically responsive material disposed in a polymer. At least a portion of the particles in a localized region of the optical effect coating are commonly oriented to produce an optical effect at the localized region.

The present invention discloses a manufacturing method of color filter. The method comprises the following steps. First, the method deposes a first color material on the substrate via a first pattern mask, forming a first color pattern, and a spray coating method is used for spraying a first color material on the substrate via the first pattern mask, therefore to form a first color pattern. Thereafter, the first pattern mask is removed and cleaned a first residual material of the first color material via laser or blow gun. The abovementioned steps will be repeated for three times to finish the color filter.
