No: 18/494087 Application Filed: October 25, 2023 Assignees: TMG – Tecidos Plastificados e Outros Revestimentos Para a Indústria Automóvel, S.A. (S Cosme do Vale, PT) Claim: 1. A composite structure comprising a translucent layer (1) having a light transmittance of 1 to 50%, an opaque layer (2) being covered by the translucent layer (1) and containing a translucent area (6), and a touch sensor (11) fully arranged below the opaque area of layer (2), wherein the translucent layer (1) or a lacquer layer (9) covering the translucent layer (1) is the uppermost layer of the composite structure, and the translucent area (6) of the opaque layer (2) is a void area surrounded by an opaque part. Claim: 2. The composite structure according to claim 1, wherein the opaque layer (2) containing the translucent area (6) is a mask layer printed on the underside of the translucent layer (1). Claim: 3. The composite structure according to claim 1, wherein the opaque layer (2) containing the translucent area (6) is a mask layer printed on the underside of the translucent layer (1) and the touch sensor (11) is printed on the underside of the mask layer. Claim: 4. The composite structure according to claim 1, containing, in this order, the translucent layer (1), the opaque layer (2) containing a translucent area (6), and a sensor layer (3), wherein the sensor layer (3) comprises a touch sensor area (5) and at least electric conductors connected thereto, wherein the touch sensor area (5) contains the touch sensor (11) and a translucent area (12) at least partially arranged below the translucent area (6) of the opaque layer (2). Claim: 5. The composite structure according to claim 4, wherein the opaque layer (2) containing a translucent area (6) is a mask layer printed on the underside of the translucent layer (1) and the sensor layer (3) is printed on the underside of the mask layer. Claim: 6. The composite structure according to claim 1, containing a support layer (4) at its underside, wherein the support layer (4) is translucent or at least partially translucent. Claim: 7. The composite structure according to claim 6, containing a light source (10) arranged in or attached to at least one of the layers selected from the sensor layer (3) and the support layer (4). Claim: 8. The composite structure according to claim 1, comprising a soft layer that is contained in the translucent layer (1) below one or more compact layers (7). Claim: 9. The composite structure according to claim 6, comprising a soft layer that is contained between the support layer (4) and the sensor layer (3). Claim: 10. The composite structure according to claim 1, wherein the translucent layer (1) is the visible side of the composite structure and is selected to render the other elements of the composite structure invisible in the absence of light emitted from the light source (10) arranged in or at the rear side of the composite structure. Claim: 11. The composite structure according to claim 10, wherein the translucent elements are selected to allow and the opaque areas are selected to inhibit transmittance of visible light emitted from the light source (10) arranged in or at the rear side of the composite structure.
