A method for using a rewritable thermal label of the non-contact type
which comprises recording and erasing information repeatedly in
accordance with a non-contact method on a rewitable thermal label which
remains attached to an adherend. The label contains (a) an anchor coat
layer comprising a crosslinked resin, (b) a heat-sensitive color
development layer, (c) a light absorption and a photo-thermal conversion
layer and (d) an adhesive layer. The layers (a), (b), (c) and (d) are
laminated on a first face of a substrate successively. The anchor coat
layer is placed next to the substrate. The layer (c) is an outermost
layer. The adhesive layer is placed on a second face of the substrate.
