Multi-layer composite body having a surface-forming UV-hardened coating (1) with a thickness of 1 - 20 µm, said coating having the following properties: a) loss of gloss not in excess of 30%, preferably not in excess of 20% measured in accordance with a micro-scratch resistance test based on prEN 16094 (issue date 2010-05-15: "Laminate floor coverings - Test method for the determination of micro-scratch resistance"), b) a numerical evaluation of ≥ 3, measured during a chemical resistance test according to DIN EN 12720 (issue date July 2009: "Furniture - Assessment of surface resistance to cold liquids") using acetone as a test liquid for an exposure time of 1 h, c) a gloss of at least 80, preferably at least 85 GLE measured according to ISO 2813 (issue date 1999-06-01: "Paints and varnishes - Determination of specular gloss of non-metallic paint films at 20°, 60° and 85°") at an observation angle of 20° and d) reflection haze not in excess of 20, preferably not in excess of 15, measured according to ISO 13803 (issue date 2004-09-01: "Paints and varnishes - Determination of reflection haze on paint films at 20°"); bending device for the composite body. |
