であつてもよい。 3 is a thermosensitive coloring layer formed on the surface of the label base material 1. The heat-sensitive coloring layer 3 is formed by applying a heat-sensitive coloring agent consisting of solid particles of a dye such as leuco, lactone, or lactam that is colorless or light-colored at room temperature and a heat-sensitive element such as an acidic substance that causes the dye to develop color. Alternatively, an opaque porous layer is laminated on the surface of the label base material 1 as a thermosensitive coloring layer 3, and when heated, the thermosensitive coloring layer 3 is dissolved, and the fine irregularities and voids on the surface of the porous layer are removed. It may be one that disappears and becomes transparent, so that the color of the label base material 1 is developed.

外線吸収剤が添加されたものを用いるとよい。 4 is a protective sheet laminated on the surface of the thermosensitive coloring layer 3. As the protective sheet 4, for example, a synthetic resin sheet or film such as a stretched polypropylene film is used, and such a synthetic resin sheet or film is added with an ultraviolet absorber such as a benzotriazole type, benzophenone type, or substituted acrylonitrile type. It is better to use something similar.

It is something to do. When using the label base material 1, in order to make it easier to peel off than the release sheet 5, a release agent such as silicone resin is applied to the surface of the paper, processed paper, polyester, polyethylene, polypropylene, etc. used as the release sheet 5. You can use one coated with.

ことができることになる。 The present invention is configured as described above, and a heat-sensitive coloring layer is formed on the surface of the label base material, and a protective sheet is laminated on the surface of the heat-sensitive coloring layer.
It is less affected by humidity, etc., and the ultraviolet light is absorbed by the ultraviolet absorber in the protective sheet, making the energy of the light into a stable form, so the heat-sensitive coloring layer will not discolor even if exposed to sunlight. Therefore, even when used as a barcode label, predetermined optical characteristics can be maintained and reading by a reading device can be performed accurately, making it possible to widen the range of uses of the label.
