Abstract
Abstract A decorative object comprising an acrylic glass support plate and differently colored polymethyl methacrylate layers and zones thereupon, on one or both major surfaces of the plate, differently colored zones and vertically superposed layers of polymethyl methacrylate being separated from each other and from the support plate by barrier elements and layers respectively which are optically and mechanically compatible with but completely insoluble in and unpenetrable by polymethyl methacrylate.
