Title:
DECORATIVE SHEET AND INTERIOR MEMBER
Document Type and Number:
WIPO Patent Application WO/2023/190260
Kind Code:
A1
Abstract:
A decorative sheet (2) comprises, from the front side to the back side, a skin layer (3), an intermediate layer (4), a design layer (5), and a soft layer (7). Recesses (6A to 6D) are open on a front surface and/or a back surface of the design layer (5). The decorative sheet (2) further comprises a plurality of display regions (A1 to D1) formed by the recesses (6A to 6D). The plurality of display regions (A1 to D1) display a predetermined design on a front surface of the skin layer (3) by light emitted from the back side. Light is emitted from the back side to the plurality of display regions (A1 to D1) through the soft layer (7). Light-blocking partition parts (710AB to 710CD) of the soft layer (7) are each disposed between two adjacent display regions (A1 to D1) when viewed from the front side, and prevent light to be emitted to one display region (A1 to D1) from leaking into the other display region (A1 to D1) through the soft layer (7).
