  • Publication number: 20210155031
    Abstract: A method for manufacturing a decorative material, the method including a step of creating density distribution data having a density value D(x, y) for each two-dimensional position (x, y); a step of converting the density value D(x, y) into a height H(x, y) corresponding to how large the concentration value is; a step of converting the height H(x, y) into a depth F(x, y) that corresponds to the height; a step of forming irregularities on a surface of a material to be a die based on the depth F(x, y) to form the die; and a step of shaping a resin with respect to the irregularities of the die to form irregularities on a surface of the resin.

  • Patent number: 9327435
    Abstract: The present invention provides a laminate-type decorative sheet for use in simultaneous decoration and injection molding, including a base film and at least a decorative layer provided on the base film, the decorative sheet having an elongation at break as measured at 25° C. of 3 to 10%, and an elongation at break as measured at 120° C. of 200% or more. The laminate-type decorative sheet exhibits good conformability to the molding surface of a mold during the course of preforming, and is less likely to produce wrinkling, blistering, breakage, etc. when laminated on and united with a resin molding through injection molding. In addition, the decorative sheet enables easy trimming.

  • Patent number: 9321203
    Abstract: Provided is a decorated sheet for insert molding in which at least a base sheet, a print layer and a surface resin layer are laminated, wherein the above base sheet comprises an ABS resin having a butadiene content of 10 to 33% by weight based on the total component, and the surface resin layer has a thickness of 50 to 150 ?m. Capable of being provided is a novel decorated sheet which does not generate harmful gases such as a chlorine gas and the like in burning and therefore does not bring about problems such as environmental pollution and the like and which is excellent in a so-called vacuum molding property and can suitably be used for various interior decorations of automobiles and the like.

  • Patent number: 9168722
    Abstract: A low glossiness-metallic luster decorative sheet with a low glossiness feeling added to a metallic luster feeling, and a laminated body thereof. Glossiness change at the time of molding is reduced. In a configuration with a metallic luster layer, and a low glossiness-resin layer containing a delustering agent provided to a substrate sheet in the order of the low glossiness-resin layer and the metallic luster layer from the closer side when viewed from one side, the low glossiness-resin layer has a large number of minute opening parts such that the metallic luster layer can be observed in the minute opening parts without the low glossiness-resin layer. By laminating the same onto the substrate by such as a molding method, a laminated body can be provided. The metallic luster layer viewed in the minute opening parts realizes a high brilliance metallic luster feeling while providing low glossiness.

  • Patent number: 9162429
    Abstract: A decorative sheet for injection-molding and decorating a resin simultaneously, the decorative sheet containing two resin sheets laminated on each other with at least one patterned layer intervening therebetween, and the two resin sheets having a difference in linear expansion coefficient of 4×10?5/° C. (41 to 50° C.) or less. Even after subjecting to three-dimensional processing, such as vacuum molding, the decorative sheet suffers no warpage, and can be easily released from a mold for the three-dimensional processing, and even when the decorative sheet is set in a mold for injection molding, the decorative sheet does not fall off from the mold, a resin injected does not permeate a gap between the outer surface of the decorative sheet and the mold, and the decorative sheet suffers no peeling between the sheets constituting the decorative sheet.
