有するようになる。First, the heat-sensitive adhesive layer 4 provided on the label substrate 1 is activated by heating to a predetermined temperature.
At this time, the microcapsules contained in the foamed resin layer 2 expand at a temperature at which the heat-sensitive adhesive layer 4 is activated, so that the foamed resin layer 2 becomes a foamed layer, and the heat-sensitive adhesive layer 4 has an adhesive property. Simultaneously, the foamed resin layer 4 has a heat insulating effect.

面にはみ出すことがなく外観も損なわない。Then, one end 1a of the label substrate 1 in which the heat-sensitive adhesive layer 2 is activated is attached to the surface of the container 7, and the label substrate 1 is wound around the body of the container 7, and The other end 1b of the label substrate 1 is adhered to the upper surface of the one end 1a, and the thermosensitive label 10 is mounted on the container. At this time, as shown in FIG. 3, the foamed resin layer 2 is not provided at the other end 1b of the overlapped portion 6 of the label base material 1 which is superimposed on the one end 1a. Does not protrude from the space between the two end portions 1a and 1b to the outer surface, and the appearance is not impaired.

ることを防止できる。Although the foaming of the foamed resin layer 2 reduces the adhesiveness between the label substrate 1 and the resin layer 2, the foamed resin layer 2 is not provided at the end of the label substrate 1. In the portions 1a and 1b, the end of the label substrate 1 can be prevented from peeling off.

きる。Further, since the foamed resin layer 2 is not provided at the upper and lower ends of the label substrate 1, the foamed resin layer 2 does not protrude from the upper and lower portions 7 a and 7 b of the container 7. Also in the upper and lower parts 7a and 7b, the foaming of the foamed resin layer 2 reduces the adhesiveness to the label base material 1 and can prevent the label base material 1 from being turned up from the upper and lower ends.

することができ、また保温効果も有する。The label-equipped container 11 having the heat-sensitive label 10 attached thereto is, for example, provided with a beverage of 60 to 80 °.
Even when heated to about C, since the foamed resin layer 2 of the thermal label 10 has a heat insulating effect, the body of the container 7 to which the thermal label 10 is attached can be gripped or used without any trouble. It can also have a heat retaining effect.

And characters and pictures on the display print layer 3a can be clearly displayed. However, in addition to the white printed layer 3b, a similar effect can be obtained if a shielding layer such as a colored printed layer or an aluminum vapor-deposited layer is formed, that is, the label substrate 1 is made opaque and the lower surface cannot be seen through.
