Abstract
The present invention provides a paper-laminated metal sheet having a structure in which at least one sheet of paper is laminated on at least one side of a metal plate via a pressure sensitive adhesive agent or an adhesive agent layer, and a protective layer is formed on a top surface of the paper-laminated side. With this structure, the paper-laminated metal sheet can be processed without wetting the paper with water, while thereby preventing the paper from being torn. In addition, the aesthetic appearance derived from the paper is kept for a long period of time. Due to high strength and processability derived from the metal base material, and high aesthetic appearance unbelievable for a metal plate derived from the paper, the paper-laminated metal sheet is valuable in various applications as a novel material.
