The invention relates to a method for creating a surface structure on a mold, wherein first structural elements are created using a laser structuring process in a first step, and second structural elements, which are smaller than the first structural elements, are created using an anodic oxidation process in another step following the laser structuring process. The invention further relates to a mold of said type and finally to a plastic film or a plastic component having a surface structure as well as to a method for the production thereof.

There is provided a new and improved master manufacturing method, master, and optical body enabling more consistent production of optical bodies having a desired haze value, the master manufacturing method including: forming a first micro concave-convex structure, in which an average cycle of concavities and convexities is less than or equal to visible light wavelengths, on a surface of a base material body that includes at least a base material; forming an inorganic resist layer on the first micro concave-convex structure; forming, on the inorganic resist layer, an organic resist layer including an organic resist and filler particles distributed throughout the organic resist; and etching the organic resist layer and the inorganic resist layer to thereby superimpose and form on the surface of the base material a macro concave-convex structure and a second micro concave-convex structure.

A stamp comprised of a soft stamp and a carrier fixed to the soft stamp.

A method of processing a sheet material (20) for use in the manufacture of products such as, but not limited to, a shoe upper blank (10). The method comprises providing a sheet material (20); providing a two-dimensional mark (30) on a surface of the sheet material (20); imposing an indentation (40) on said surface of the sheet material (20), wherein at least part of the indentation (40) is arranged with respect to at least part of the two-dimensional mark (30) to create a three-dimensional mark (50) on said surface. A blank for such a product is also related. The blank (10) comprises a sheet material (20) shaped in accordance with the product such as a shoe upper, the sheet material (20) comprising a two-dimensional mark (30) is provided thereon and is positioned with respect to an indentation (40) formed in the sheet material (20) to thereby provide a three-dimensional mark (50) on said surface.

A seat trim cover for an automotive seat is formed into a 3-dimensional shape by compression molding a laminated moldable foam in a 3-dimensional. The laminated moldable foam comprises at least a layer of cellular polyurethane foam compression moldable in a temperature range of about 220° F. to about 260° F. The 3-dimensional mold is heated to a temperature range of about 150° F. to about 320° F. The layer of cellular foam is adhered to a cover material layer and pre-cut into a pre-laminated blank prior to molding into the 3-dimensional shape. Optionally, seat heaters or other components can be integrated with the laminated foam prior to compression molding the seat trim cover.

A textured release sheet includes a substrate, which has been electron beam treated, including a top side and a bottom side. A matte surface is formed on the bottom side thereof, wherein the matte surface of the surfacing material is a coating of an radiation curable material applied to the bottom side of the substrate. The coating is an UV curable acrylate mixture applied to the substrate, wherein the UV curable acrylate mixture is irradiated with UV-radiation via an excimer laser emitter to produce a UV-irradiated layer wherein the UV curable acrylate mixture is only crosslinked on the surface thereof, which produces a matting surface through the effects of a micro-convolution.

A pattern forming method of forming, with a mold, a pattern on a substrate held by a substrate holding unit capable of changing a holding force for each holding region includes setting, with a plurality of shot regions corresponding to a first holding region as a target for pattern formation, a first holding force in the first holding region smaller than a second holding force in a second holding region different from the first holding region, coating, with an imprint material, a region including the plurality of shot regions corresponding to the first holding region, and forming the pattern on the substrate by bringing the imprint material, with which the plurality of shot regions corresponding to the first holding region is coated, and the mold in contact with each other.

An imprinting method, which includes following steps. A workpiece is conveyed to a working region by a first conveyer unit. The workpiece is imprinted in the working region through an imprinting segment of a flexible imprinting mold film. The flexible imprinting mold film is driven by a driving roller set, such that at least another one of the imprinting segments of the flexible imprinting mold film rolled around the driving roller set is expanded from the driving roller set and moved to the working region.

According to one embodiment, under a condition that a substrate is installed on a substrate installation unit, a mold is installed on a mold installation unit, and a mask unit is installed in a mask-unit installation unit, a transfer apparatus controls an operation of a mold presser unit so as to press the mold against the substrate, the operation of a first positioning unit so as to position the mask unit with respect to the mold and the operation of an irradiation unit so as to irradiate an uncured material provided on the surface of the substrate with electromagnetic waves of a predetermined wavelength.

The method for fabricating pattern of a cured product includes a first step (arranging step) of arranging a layer formed of a liquid film of a curable composition (α1) containing at least a component (A1) serving as a polymerizable compound on a substrate and a second step (dispensing step) of dispensing liquid droplets of a curable composition (α2) containing at least a component (A2) serving as a polymerizable compound discretely onto a layer formed of a composition (α1′) of components of the curable composition (α1) except a component (D1) serving as a solvent, in which: the mixing of the composition (α1′) and the curable composition (α2) is exothermic.
