Laminating material, adhesive label-laminating material set, adhesive body and recovery method

Abstract

To provide a laminate material that allows for accurate determination of the material of an object even when an adhesive label is attached to its surface; to provide an adhesive label-laminated material set that allows for accurate determination of the material of an object even when attached to its surface; to provide an adhesive that allows for accurate determination of the material of an object with an adhesive label attached to its surface; and to provide a recovery method that allows for suitable separation and recovery of an adhesive with an adhesive label attached to its surface. [Solution] The laminate material of the present invention is a laminate material that is attached to an adhesive label attached to an adherend, and comprises a base material, an adhesive layer disposed on one side of the base material, and a release coating layer disposed between the base material and the adhesive layer, wherein the base material is made of the same type of resin material as the resin material constituting the adherend.

Claims

3. The laminate material according to claim 1 or 2, wherein the thickness of the substrate is 10 μm or more and 150 μm or less.

4. The laminate material according to claim 1 or 2, wherein the thickness of the desorbed coating layer is 0.01 μm or more and 3.0 μm or less.

5. The laminate material according to claim 1 or 2, wherein the desorbed coating layer is made of a material containing an aqueous polyester resin having an acid value of 10 KOH mg / g or more and a glass transition temperature Tg of 0°C or more and 70°C or less.

6. The laminate material according to claim 1 or 2, wherein the adhesive layer is made of a material containing an acrylic adhesive.

7. The invention comprises an adhesive sheet for labels used in the manufacture of adhesive labels to be attached to an object, and a laminating material to be attached to the adhesive label, The adhesive sheet for labels comprises a label substrate and an adhesive layer for labels disposed on one side of the label substrate. The laminate material comprises a base material, an adhesive layer disposed on one side of the base material, and a de-icing coating layer disposed between the base material and the adhesive layer. An adhesive label-laminating material set characterized in that the base material is made of the same type of resin material as the resin material constituting the adherend.

8. The adhesive label-laminating material set according to claim 7, wherein the adhesive layer for the label is a wash-off type adhesive layer.

9. The adhesive sheet for labels further has a label release coating layer on the side of the label substrate opposite to the side facing the adhesive layer for labels. The adhesive label-laminating material set according to claim 7, wherein the label substrate and the label adhesive layer are made of the same type of resin material as the resin material constituting the adherend.

10. It comprises a substrate, an adhesive label attached to the substrate, and a laminate material attached to the adhesive label. The adhesive label comprises a label substrate, an adhesive layer for labels disposed on one side of the label substrate, and a printing layer disposed on the other side of the label substrate. The adhesive layer for the label is in contact with the adherend. The laminate material comprises a base material, an adhesive layer disposed on one side of the base material, and a de-icing coating layer disposed between the base material and the adhesive layer. The adhesive layer is in contact with the printed layer, The adhesive is characterized in that the base material is made of the same type of resin material as the resin material constituting the adherend.

11. A recovery method characterized by applying a liquid to the adhesive according to claim 10, thereby separating and recovering at least the adherend and the substrate from the portion including the printed layer.

12. The recovery method according to claim 11, wherein the liquid is an alkaline liquid.

13. The adhesive layer for the label is a wash-off type adhesive layer. The recovery method according to claim 11 or 12, wherein the adherend and the substrate are separated and recovered from the portion including the printing layer and the label substrate.

14. The adhesive label further has a label release coating layer on the side of the label substrate opposite to the side facing the label adhesive layer. The label substrate and the label adhesive layer are made of the same type of resin material as the resin material constituting the adherend. The recovery method according to claim 11 or 12, wherein the substrate and the adherend to which the label substrate is bonded via the label adhesive layer are separated from the portion including the printing layer and recovered.
