  The pressure-sensitive adhesive sheet according to the present invention includes a mount made of a paper material, a non-adhesive layer made of a coating agent such as silicon coated on one surface side of the mount, and an ink formed on the other surface side of the mount The adhesive layer is disposed on the non-adhesive layer with a plurality of sheet-like laminates including a layer and an adhesive layer made of an adhesive applied on the other surface of the mount and the ink layer. It is characterized by overlapping.

  According to the above configuration, the recovered non-adhesive mount can be effectively used, and an environmentally advantageous structure can be realized.

  In the pressure-sensitive adhesive sheet according to the present invention, the mount and the non-adhesive layer form a non-adhesive mount, and the non-adhesive mount is recovered from a seal label on which the non-adhesive mount is previously lined. The ink layer is made of an ultraviolet curable ink, and the adhesive layer is made of a water-soluble adhesive. Even in this case, it is easy to handle and the recovered non-adhesive mount can be effectively used, and an environmentally advantageous structure can be realized.

  Furthermore, in the pressure-sensitive adhesive sheet according to the present invention, the mount is paper or a film, the ink is an ultraviolet curable ink or a gravure ink, and the pressure-sensitive adhesive is a water-soluble pressure-sensitive adhesive, a hot melt or a solvent-based pressure-sensitive adhesive. One of them.

  The pressure-sensitive adhesive tape according to the present invention includes a mount made of a paper material, a non-adhesive layer made of a coating agent such as silicon coated on one surface side of the mount, and an ink formed on the other surface side of the mount A tape-like laminate comprising a layer and an adhesive layer made of an adhesive applied on the other surface of the mount and the ink layer so that the adhesive layer is disposed on the non-adhesive layer It is characterized by being wound up.

  According to the above configuration, the mount having the collected non-adhesive layer can be effectively used, and an environmentally advantageous structure can be realized.

  As described above, according to the present invention, the recovered non-adhesive mount can be effectively used, and an adhesive sheet and an adhesive tape having an environmentally advantageous structure can be provided.

  Next, an embodiment of an adhesive sheet and an adhesive tape according to the present invention will be described based on the drawings.

  FIG. 1 is an external perspective view showing an example of the overall configuration of an adhesive sheet according to an embodiment of the present invention. Moreover, FIG. 2 is sectional drawing which shows an example of the structure of the laminated body which comprises the adhesive sheet. Moreover, FIG. 3 is sectional drawing which shows an example of the laminated structure of the laminated body which comprises the adhesive sheet.

  As shown in FIG. 1, the pressure-sensitive adhesive sheet 10 is formed, for example, in a rectangular sheet shape, and is configured by stacking stacked bodies 11 in a plurality of thickness directions. As shown in FIG. 2, the pressure-sensitive adhesive sheet 10 having such a configuration includes, for example, a mount 12 made of a paper material and a coating agent such as silicon (Si) coated on one surface 12 a side of the mount 12. A non-adhesive layer 13; an ink layer 14 formed on the other surface 12b side of the mount 12; and an adhesive layer 15 made of an adhesive applied on the other surface 12b of the mount 12 and the ink layer 14. As shown in FIG. 3, the sheet-like laminate 11 has a structure in which a plurality of stacked layers 11 are stacked in the thickness direction so that the adhesive layer 15 is disposed on the non-adhesive layer 13.

  The mount 12 is, for example, normally available tack paper, such as SS fine tack paper manufactured by Lintec Corporation, SS foil tack paper, SS art tack paper, SS gloss stack paper, high quality tack paper manufactured by Oji Tack, Mira Coat Tack paper, foil tack paper, art tack paper, and the like are suitable, but are not limited to these, and a film may be used. The mount 12 is not particularly limited as long as it is made of a material that can form the ink layer 14 on one side (the other surface 12b). The mount 12 may be a recycled sticker mount (that is, non-adhesive mount) of a conventional seal label.

  The non-adhesive layer 13 is made of a sliding agent (coating agent) such as silicon coated on the one surface 12 a side of the mount 12. As described above, when the mount 12 backed by the seal label is recovered as a non-adhesive mount, the non-adhesive layer 13 and the mount 12 constitute a non-adhesive mount. The ink layer 14 is formed, for example, by printing on the other surface 12b side of the mount 12 and is appropriately determined according to the material of the mount 12, such as mineral oil-based ink, dry vegetable oil ink, and resin-based ink. Although suitable, ultraviolet curable ink or gravure ink may be used.

  The pressure-sensitive adhesive layer 15 is composed of at least one type of pressure-sensitive adhesive applied on the surface 12b and the ink layer 14, and for example, a water-soluble pressure-sensitive adhesive is suitable in terms of the environment, such as an acrylic emulsion resin-based pressure-sensitive adhesive and a natural rubber-based pressure-sensitive adhesive. Adhesives, synthetic rubber adhesives, acrylic resin adhesives, urethane resin adhesives, silicon resin adhesives, polyvinyl ether resin adhesives, and the like are suitable. In addition, a hot melt or a solvent-based pressure-sensitive adhesive can also be used.

  According to the pressure-sensitive adhesive sheet 10 configured as described above, a release layer (release paper), a protective layer, and the like are not required as in a conventional seal label. Further, the non-adhesive backing sheet lined with the seal label can be recycled and used as the backing sheet 12 (including the non-adhesive layer 13) of the adhesive sheet 10. For this reason, the mount 12 (non-adhesive mount) having the collected non-adhesive layer 13 can be effectively used, and an environmentally advantageous structure can be realized.

  Further, according to the pressure-sensitive adhesive sheet 10, since the ink layer 14 is formed between the pressure-sensitive adhesive layer 15 and the surface 12 b of the mount 12, the adhesive force between the pressure-sensitive adhesive layer 15 and the ink layer 14 is increased. If it is set higher (stronger) than the adhesive strength with the adhesive 12, the ink layer 14 is also broken and peeled off when the backing 12 is peeled off from the adhesive after the backing 12 is attached to the adhesive. Can do. For this reason, when specific information (a character, a picture, etc.) is comprised by the ink layer 14, it can be used for uses, such as what is called an opening prevention label, and can also be used for uses, such as a falsification prevention.

  FIG. 4 is an external perspective view showing an example of the overall configuration of an adhesive tape according to another embodiment of the present invention. In the following description, the same parts as those already described are denoted by the same reference numerals and description thereof is omitted. As shown in FIG. 4, the adhesive tape 20 is formed in a tape shape, for example, and the laminate 11 shown in FIG. 2 is wound around the roll core 21 so that the adhesive layer 15 is disposed on the non-adhesive layer 13. Taken and configured. Since the structure of the laminated body 11 is the same as that of the adhesive sheet 10 mentioned above, description is abbreviate | omitted here. The roll core 21 may be wound up without being used.

  According to the pressure-sensitive adhesive tape 20 configured as described above, a release layer (release paper), a protective layer, and the like are not required as in a conventional sheet label. Further, the non-adhesive backing lined on the seal label can be recycled and used as the backing sheet 12 (including the non-adhesive layer 13) of the adhesive tape 20. For this reason, the mount 12 (non-adhesive mount) having the collected non-adhesive layer 13 can be effectively used, and an environmentally advantageous structure can be realized. Moreover, according to this adhesive tape 20, similarly to the said adhesive sheet 10, it can be used for uses, such as what is called an opening prevention label, and can be used for uses, such as a falsification prevention.
