Abstract
Abstract A signboard is provided which is comprised of a flexible weather-proof macromolecular sheet, a colored paint coated on the front surface of the sheet in the form of a design or message and a self-sticking adhesive layer containing rubber and bituminous material on the back surface of the sheet. The signboard may be stuck readily to substantially any surface to convey a message therefrom and it then forms a protective coating on the surface to which it is stuck. The signboard may also contain a luminous layer composed of glass granules and a transparent finish on the front surface of the sheet whereby the message or design may be seen readily, even at night, by reflected light.
