ABSTRACT OF THE DISCLOSURE This invention provides a thermal recording medium which has a metallic thin layer, a heat sensitive layer formed on said metallic thin layer and a contrast layer formed on either said heat sensitive layer or the above metallic thin layer and visually contrasting with the above metallic thin layer. A thermal recording medium having a roughed metallic thin layer can be produced by using a material containing minute particles to form a roughed heat sensitive layer or a roughed contrast layer prior to the formation of the metallic thin layer and depositing it on the roughed heat sensitive layer or the roughed contrast layer. A desired pattern is thermally recorded by heating in said desired pattern the heat sensitive layer and the metallic thin layer of the above thermal recording medium to melt the heated areas of said metallic thin layer and disperse the molten metallic thin layer as fine particles into the heat sensitive layer touching said metallic thin layer thereby destroying it in the above desired pattern.
