  • Patent number: 11958219
    Abstract: The present disclosure provides a foam molded product and a manufacturing method. The foam molded product is includes a foam body, an insert material having a display unit or a detection unit attached to the foam body, and a surface material affixed to a surface to which at least the insert material is attached. A manufacturing method includes: preparing a pair of molds including a first mold and a second mold; affixing an insert material and a surface material together such that the surface material is in contact with a molding surface of the first mold; closing the pair of molds; injecting a foam resin into a molding space formed by closing the molds; foaming the foam resin to form a foam body; opening the pair of molds; and removing a molded product in which the affixed part and the foam body are integrated.

  • Publication number: 20240100879
    Abstract: In a decorative sheet according to the present invention, a design layer has a light passing area in which light passing through a transparent sheet is caused to pass through by a plurality of micro holes. Each of the plurality of micro holes includes a first slit and a second slit on which ink or a deposition film is not put. In each of the micro holes, the first slit and the second slit cross each other. Thus, visibility of a secondary object displayed by passing light is improved, while a reduction in quality of a primary object displayed mainly when light is not caused to pass through is prevented.

  • Patent number: 11697234
    Abstract: Provided is a decorative sheet in which a graphic is less deteriorated even after injection molding. First and second graphic layers contain a plurality of interference pigments that emit respective interference lights having respective colors in a first direction in first and second binders to exhibit first and second mixed colors. An optical functional layer changes a reflectance property of light. The first and second graphic layers represent a graphic visually recognizable from a front surface of a decorative sheet and allow visually recognizing an image displayed on a back surface from the front surface. The optical functional layer increases at least one of ratios of an amount of visible light representing the graphic and an amount of visible light representing the image that transmits through the first and second graphic layers to an amount of visible light reflected by and visible on the front surface.

  • Patent number: 11285693
    Abstract: To provide a decorative molded article that enables clear visual recognition of an arbitrary pattern on a surface of a skin material when a light source is turned on. The decorative molded article is a decorative molded article capable of being illuminated by a light source on a back surface and configured so that a skin material having an OD value of 1 or more and 3.5 or less, a light-shielding layer having an arbitrary pattern, and a transparent molded body are laminated together in sequence, and so that a color difference ?E between a light emitting unit and a non-light emitting unit of the skin material is 50 or more when the light source is turned on. The decorative molded article may further include a nonwoven fabric between the skin material and the light-shielding layer, or between the light-shielding layer and the molded body.

  • Patent number: 10981368
    Abstract: Provided are a decorative glass panel having a three-dimensional metal design and a manufacturing method for the decorative glass panel, the method exhibiting enhanced productivity. A decorative glass panel 10 includes: a glass substrate 15; an adhesive layer 11 formed on the glass substrate 15; a non-uniform pattern layer 12 formed on the adhesive layer 11; and a vapor-deposited metal layer 13 formed on the non-uniform pattern layer 12. In the glass substrate 15, a section that is a portion of a back surface of the glass substrate 15 and that is bent from a flat surface section 30 to an upright section 31 forms a curved surface 32. The non-uniform pattern layer 12 has, in a surface facing the vapor-deposited metal layer 13, which is a top surface thereof, a non-uniform pattern formed by depressions 40 and protrusions 41.

  • Publication number: 20180310553
    Abstract: Provided is an antiviral transfer sheet manufacturing method for increasing the density of an antiviral agent or antibacterial agent in a surface which becomes an upper-most layer after transfer. In particular, a manufacturing method that eliminates the need for a large amount of an antiviral agent and the like, and the opacity of the layer having antiviral function is provided. A functional layer 37 including an inorganic antiviral agent powder and a hard coat agent is formed on one surface of a base material sheet 31 by disposing on the base material sheet the inorganic antiviral agent powder 33, and positioning the hard coat agent 34 in layer shape from over the inorganic antiviral agent powder 33. Then, an adhesive layer 39 is formed on the functional layer 37 in contact with the functional layer 37 or via another layer, thereby manufacturing an antiviral transfer sheet 11.
