Abstract: The invention relates to a recording material for the inkjet method having a particularly glossy surface, a substrate material having a metal layer on at last one of its surfaces and it being possible for this metal layer additionally to be provided with a protective layer. The material thus obtained carries an ink-accepting layer on one of the following surfaces: 1. on the metal layer, 2. on the protective layer cover the metal layer, 3. on that surface of the substrate material which faces away from the metal layer. When an image is recorded on the ink-accepting layer on a commercial inkjet plotter, particularly interesting reflecting color effects are obtained, in particular colors such as silver, gold, golden red, etc. being produced, which are not achievable by means of a conventional inkjet recording method.
