Abstract
The present invention bonds a label to an adherend with a heat-sensitive adhesive layer disposed therebetween, by sufficiently activating the heat-sensitive adhesive layer. Prepared is a label which comprises a label base and a heat-sensitive adhesive layer disposed on the back surface of the label base, wherein an ultraviolet-absorbing heating agent is contained in an area of the label base which at least includes the disposed heat-sensitive adhesive layer and/or in the heat-sensitive adhesive layer. Before or after the label is applied to an adherend, irradiation with ultraviolet is conducted to activate the heat-sensitive adhesive layer.
