摘要：PROBLEM TO BE SOLVED: To demonstrate a visible image in various tones by disposing a heat- sensitive recording resin layer formed of a blend of a reversible heat-sensitive coloring material with a light transmitting resin matrix on a printed layer divided into a plurality of divisions. SOLUTION: Printing, in which a number of kinds of plastic printing materials of colors like red, yellow, gray and others are printed by the silk screen method or the like and printed divisions 2 of square shape of respective different colors are formed at intervals, is carried out on a substrate layer 1 formed of a white PET film. A support film layer 3 of a transparent PET base is so formed as to coat all the printing divisions 2, and a heat-sensitive recording resin layer 4 formed of a light transmitting resin matrix blended with a reversible heat-sensitive coloring material containing a leuco dye is overlapped thereon, and also a PET protective layer 4a is overlapped, heat pressure bonded and laminated integrally thereon. When printing is carried out by a thermal head on the reversible heat-sensitive recording sheet, blue characters can be visualized on red, yellow and gray printed layers by the coloring of the leuco dye, and various tones on respectively different divisions on the printed layer can be demonstrated on the surface of the sheet.
