Abstract
Abstract A surface protecting material is prepared by having a soft aluminum foil having a thickness of 15 to 50μ superposed on the surface of a substrate of plastic film such as polyethylene, polyvinyl chloride, or polyester and further having a layer of resin containing at least 10% fluorine resin or silicone resin and having not more than 1μ in surface coarseness superposed directly on the surface of the aluminum foil or indirectly thereon through the medium of a colored layer formed thereon. This surface protecting material is useful for decorating and repairing various kinds of goods and to obtain a flat surface thereon.
