A method for producing flakes of a resin thin film including: a step (1) of forming a resin thin film on a substrate film to obtain a multilayer film; a step (2) of pressing the multilayer film by a member having a concavo-convex shape to form cracks in the resin thin film; and a step (3) of stripping the resin thin film from the substrate film to obtain flakes. The step (2) is preferably performed with a pressing pressure of 100 MPa or less. The resin thin film is preferably formed of a cured product of a photocurable liquid crystal composition. The resin thin film is preferably a cholesteric resin layer.

An imprint apparatus that performs an imprint process of forming a pattern of an imprint material on a substrate using a mold, the apparatus including a control unit configured to control a mold driving unit and a substrate driving unit, and the imprint process including curing the imprint material, and releasing the mold from the cured imprint material, wherein the control unit includes a compensator configured to feedback-control driving of at least one of the mold driving unit and the substrate driving unit such that a positional relationship between the mold and the substrate in the releasing is maintained at a positional relationship between the mold and the substrate in the curing, and makes a gain of the compensator in the releasing smaller than a gain of the compensator in a step of the imprint process other than the releasing.

Disclosed are methods for forming a double-sided optical sheet, and a vehicle lamp assembly having the double-sided optical sheet integrated therein. A first optical pattern is imprinted on a first side of a material, and a second optical pattern is imprinted on a second side of the material, opposite the first side. The first and second optical patterns are thereby formed on opposing sides of the same sheet. When oriented adjacent a light source, the double-sided optical sheet homogenizes light emitted from the light source. For a light source having a plurality of lighting elements, the double-sided optical sheet is configured to blend light emitted from the plurality of lighting elements to form one homogenous beam of light output resulting from a single light-modifying member.

Forming features in the surface of a bicycle component involves depositing a substance onto a substrate in a geometric pattern to form a transfer medium. Forming features may also involve positioning the transfer medium relative to an unformed bicycle component, and forming a negative of the geometric pattern in the bicycle component through the application of heat and/or pressure to the transfer medium and the unformed bicycle component. The transfer medium may be configured for use in the molding of carbon fiber reinforced plastic (“CFRP”) bicycle components and may include a substrate formed of a flexible material, and a geometric pattern formed of a hard material, the hard material different than the flexible material.

The invention relates to a decorative panel and to a method for producing a decorative panel, in particular a floor panel, wall panel or ceiling panel. The method comprises the steps of providing at least one decorative panel, the panel comprising a core layer comprising an upper surface and a bottom surface, applying at least one uncured coating onto the upper surface of the panel such that a coating layer is formed, creating a surface texture in the coating layer and curing the coating layer via UV curing.

There is provided a simulation method of predicting a behavior of a curable composition in a process of bringing a plurality of droplets of the curable composition arranged on one of a first member and a second member into contact with an other of the first member and the second member and forming a film of the curable composition on the first member. The method includes generating a link by connecting two adjacent representative points of the plurality of droplets, generating a cell as a closed region formed by a plurality of links, and determining, based on the presence/absence of merging of droplets corresponding to each link forming the cell, whether a bubble is formed in the cell.
