发明名称 A RESIN-COATED METAL SHEET WITH HIGHER VIVID REFLECTIVITY HAVING THE EXCELLENT WORKABLE ADHESION STRENGTH
摘要 In a resin-coated metal sheet, at least one surface of a metal sheet 10 as a base sheet is overlaid by a transparent polyester resin film A of 5 to 100 .mu. m thickness through a paint layer E, a modified olefin resin layer D of 5 to 100 .mu. m thickness, a pattern or/and solid printing layer C and an adhesive layer B which layers are put one over another in order from the side of the metal sheet toward the transparent polyester resin film. Since the modified olefin resin layer which is provided in between the transparent polyester resin film and the metal sheet has the excellent adhesiveness against the printing layer, the paint layer and the polyester resin film, even if the resin-coated metal sheet is formed under the severe condition against the resin-coated metal sheet, for instance by deep drawing, delamination does not occur so that the excellent workable adhesion strength is shown. Further, the roughness of the surface of the metal sheet, and unevenness of several component resin layers are absorbed by a modified olefin resin layer so that the excellent vivid relectivity for a resin-coated metal sheet can be obtained.
