Abstract:
A resin-coated metal sheet consisting essentially of:a. a metal sheet as a base sheet; b. modified polyolefin layer of 5 to 100 microns thickness on the metal sheet; c. wherein said modified polyolefin layer is a propylene-based resin produced by blending propylene copolymer having a carboxyl group within a molecule with polypropylene in the following ratio; 100 parts by weight to 20 parts by weight propylene copolymer; 0 parts by weight to 80 parts by weight of polypropylene; d. a preformed transparent thermoplastic polyester resin film of 5 to 100 microns thickness on the modified polyolefin layer; e. a resin coating as a protective top coat layer on said thermoplastic polyester resin film; and f. an adhesive layer comprising polyester resin, epoxy resin, melamine resin, or urethane resin, between said polyester layer and said modified polyolefin layer; g. wherein on e surface or both surfaces of the metal sheet is/are overlaid by the modified polyolefin resin layer, the adhesive layer, and the polyester resin film.
