Abstract

Provided is one of labels 101, 120, 130 and 140 , top layer materials formed on a printing medium 201, 246 and 266 , information-bearing media 301, 330, 350 and 360 , a solid fuel 401 , and a wristband clip 510 , having the function of absorbing carbon dioxide to which a new carbon dioxide absorbent is added. Provided are also carbon dioxide reduction methods of absorbing carbon dioxide by burning the same.

First claim

The invention claimed is:

1. An information-bearing medium comprising:
a plurality of layers configured to form a medium body which is capable of bearing information; and
a vesicle encapsulating a carbon dioxide absorbent configured to absorb carbon dioxide generated during incineration of the information-bearing medium,
wherein the vesicle encapsulating the carbon dioxide absorbent is included in at least one layer of the plurality of layers.

2. The information-bearing medium according to claim 1 , wherein the information-bearing medium is a thermal paper.

3. The information-bearing medium according to claim 2 , wherein the vesicle encapsulating the carbon dioxide absorbent is included in a heat-sensitive color-forming layer of the thermal paper.

4. The information-bearing medium according to claim 1 , wherein the information-bearing medium is a thermal paper,
the thermal paper includes a lamination of a heat-sensitive color-forming layer on the medium body composed of a paper material, and
the vesicle encapsulating the carbon dioxide absorbent is included in the heat-sensitive color-forming layer.

5. The information-bearing medium according to claim 1 , wherein the information-bearing medium includes a lamination of a heat-sensitive color-forming layer on the medium body, the medium body being composed of a plastic material, and
the vesicle encapsulating the carbon dioxide absorbent is included in the heat-sensitive color-forming layer.

6. The information-bearing medium according to claim 1 , wherein the information-bearing medium is configured to be usable in a printer.

7. The information-bearing medium according to claim 1 , wherein the vesicle encapsulating the carbon dioxide absorbent is particulate.

8. The information-bearing medium according to claim 1 , wherein the vesicle encapsulating the carbon dioxide absorbent is nanometer in size.

9. The information-bearing medium according to claim 8 , wherein the vesicle encapsulating the carbon dioxide absorbent is about 10 to 100 nm in size.

10. The information-bearing medium according to claim 1 , wherein a plurality of vesicles encapsulating carbon dioxide absorbent are uniformly dispersed in said layer.

11. The information-bearing medium according to claim 1 , wherein a plurality of vesicles encapsulating carbon dioxide absorbent are included at a mixture ratio of 0.01 weight % or more and 0.10 weight % or less in one layer to which the plurality of vesicles encapsulating carbon dioxide absorbent are added.

12. The information-bearing medium according to claim 1 , wherein the carbon dioxide absorbent is a material that reacts with the carbon dioxide generated from the medium body during the incineration so that the carbon dioxide remains in ash formed by the incineration.

13. The information-bearing medium according to claim 12 , wherein carbon dioxide generated from the medium body during the incineration is not released into the air.

14. The information-bearing medium according to claim 1 , wherein the carbon dioxide absorbent comprises:
a carbon dioxide-absorbing substance;
a dispersion aid that covers a surface of the carbon dioxide-absorbing substance; and
a resin.

15. The information-bearing medium according to claim 1 , wherein the vesicle is a liposome that encapsulates the carbon dioxide absorbent.

16. The information-bearing medium according to claim 15 , wherein the liposome encapsulates the carbon dioxide absorbent in a phospholipid.

17. An information-bearing medium comprising:
a plurality of layers configured to form a medium body which is capable of bearing information, and
a vesicle encapsulating a carbon dioxide absorbent configured to absorb carbon dioxide generated during incineration of the information-bearing medium,
wherein the vesicle encapsulating the carbon dioxide absorbent is included in a layer and the layer is laminated on any one of the plurality of layers.

18. The information-bearing medium according to claim 17 , wherein the information-bearing medium is a thermal paper.

19. The information-bearing medium according to claim 18 , wherein the vesicle encapsulating the carbon dioxide absorbent is included in a heat-sensitive color-forming layer of the thermal paper.

20. The information-bearing medium according to claim 17 , wherein the information-bearing medium is a thermal paper,
the thermal paper includes a lamination of a heat-sensitive color-forming layer on the medium body composed of a paper material, and
the vesicle encapsulating the carbon dioxide absorbent is included in the heat-sensitive color-forming layer.

21. The information-bearing medium according to claim 17 , wherein the information-bearing medium includes a lamination of a heat-sensitive color-forming layer on the medium body, the medium body being composed of a plastic material, and
the vesicle encapsulating the carbon dioxide absorbent is included in the heat-sensitive color-forming layer.

22. The information-bearing medium according to claim 17 , wherein the information-bearing medium is configured to be usable in a printer.

23. The information-bearing medium according to claim 17 , wherein the vesicle encapsulating the carbon dioxide absorbent is particulate.

24. The information-bearing medium according to claim 17 , wherein the vesicle encapsulating the carbon dioxide absorbent is nanometer in size.

25. The information-bearing medium according to claim 24 , wherein the vesicle encapsulating the carbon dioxide absorbent is about 10 to 100 nm in size.

26. The information-bearing medium according to claim 17 , wherein a plurality of vesicles encapsulating carbon dioxide absorbent are uniformly dispersed in said layer.

27. The information-bearing medium according to claim 17 , wherein a plurality of vesicles encapsulating carbon dioxide absorbent are included at a mixture ratio of 0.01 weight % or more and 0.10 weight % or less in one layer to which the plurality of vesicles encapsulating carbon dioxide absorbent are added.
