Abstract
A method of manufacturing a reversible heat-sensitive recording medium capable of manufacturing a reversible heat-sensitive recording medium invulnerable toward scratches, etc. even when printing/erasing is repeated under situation where dirt and dust tend to attach to the reversible heat-sensitive recording medium, thus providing increase durability of the reversible heat-sensitive recording medium against repeated printing/erasing. In the method of manufacturing the reversible heat-sensitive recording medium containing a reversible heat-sensitive recording layer and a substrate sheet, a reversible heat-sensitive recording sheet or a reversible heat-sensitive recording transfer sheet having the reversible heat-sensitive recording layer applied to the substrate sheet through welding, after which a protective layer is formed on the reversible heat-sensitive recording layer.
