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.
