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.

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.

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 ΔE 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.
