Patent number: 12163653Abstract: A decorative sheet includes, from the front side to the back side, a skin layer, an intermediate layer, a design layer, and a soft layer. Recesses open on at least one of a front surface and a back surface of the design layer. The decorative sheet further includes display regions formed by the recesses. The display regions display a predetermined design on a front surface of the skin layer by light irradiated from the back side. Light is irradiated from the back side to the display regions via the soft layer. Light blocking partition parts of the soft layer are each disposed between two adjacent display regions as seen from the front side, and prevent light to be irradiated to one display region from leaking into the other display region via the soft layer.Type: GrantFiled: March 18, 2024Date of Patent: December 10, 2024Assignees: TOKAI CHEMICAL INDUSTRIES, LTD., Sumitomo Riko Company LimitedInventor: Takemasa Okumura
