PROBLEM TO BE SOLVED: To provide a method for preventing the loosening of a thermal roll paper wound in a rolled state, without using glue. SOLUTION: In this thermal roll paper 1 composed by winding a thermal paper 4 provided with a thermal coloring layer 3 containing a water-soluble resin binder on the surface of a paper base material 2, water is applied to the whole area or a required area of at least one roll end face for having the water-soluble resin binder oozed out. By drying the water-soluble resin binder, the thermal papers are temporarily bonded each other to form a loosening preventing end part 5. |
