GUIDES DE LUMIÈRE DOTÉS D'UN REVÊTEMENT DESTINÉS À ÊTRE UTILISÉS DANS L'EAU

摘要

The invention provides a layer stack (500) comprising a first silicone layer (510), wherein the first silicone layer (510) has a first surface (511) and a second surface (512), wherein the first silicone layer (510) is transmissive for UV radiation having one or more wavelengths selected from the range of 200-380 nm, wherein the layer stack (500) further comprises one or more of: - a first layer element configured at a first side of the first surface (511), wherein the first layer element is associated by a chemical binding with the first surface (511) directly or via a first intermediate layer, which is transmissive for UV radiation having one or more wavelengths selected from the range of 200-380 nm, wherein the first layer element at least comprises a first layer differing in composition from the first silicone layer (510), and wherein the first layer element is transmissive for UV radiation having one or more wavelengths selected from the range of 200-380 nm; and - a second layer element (620) configured at a second side of the second surface (512) wherein the second layer element (620) is associated by a chemical binding with the second surface (512) directly or via a second intermediate layer, wherein the second layer element (620) at least comprises a second layer (1220) differing in composition from the first silicone layer (510).
