Claims
- 1. A reversible thermosensitive recording label for reversibly forming images and erasing recorded images thereon comprising:
- a reversible thermosensitive recording member having a temperature-dependent transparency which reversibly changes depending upon the temperature thereof,
- an adhesive layer provided on the back side of said reversible thermosensitive recording member, and
- a disposable release sheet applied to said adhesive layer, wherein said adhesive layer has such an adhesion that when said adhesive layer is applied to a label receiving material, the adhesion between said adhesive layer and said label receiving material is not less than 0.5 kgf/25 mm in terms of the average tensile load at an angle of 180.degree. measured in accordance with JIS K-6854.
- 2. The reversible thermosensitive recording label as claimed in claim 1, wherein said adhesive layer comprises a material having elasticity.
- 3. The reversible thermosensitive recording label as claimed in claims 1 or 2, further comprising a printed layer between said reversible thermosensitive recording member and said adhesive layer.
- 4. The reversible thermosensitive recording label as claimed in claims 1 or 2, wherein said adhesive layer comprises at least two adhesive layers, and an intermediate support material which is interposed between said adhesive layers.
- 5. The reversible thermosensitive recording label as claimed in claims 1 or 2, wherein said adhesive layer comprises an air-containing vacant portion therein free of adhesive agent, through which light passes.
- 6. The reversible thermosensitive recording label as claimed in claims 1 or 2, wherein said adhesive layer comprises an adhesive agent having cushioning properties.
- 7. A reversible thermosensitive recording card for reversibly forming images and erasing images thereon comprising:
- a reversible thermosensitive recording member having a temperature-dependent transparency which reversibly changes depending upon the temperature thereof,
- an adhesive layer provided on the back side of said reversible thermosensitive recording member, and
- a label receiving material to which said adhesive layer is applied, wherein the adhesion between said adhesive layer and said label receiving material is not less than 0.5 kgf/25 mm in terms of the average tensile load at an angle of 180.degree. measured in accordance with JIS K-6854.
- 8. The reversible thermosensitive recording card as claimed in claim 7, wherein said adhesive layer comprises a material having elasticity.
- 9. The reversible thermosensitive recording card as claimed in claims 7 or 8, further comprising a printed layer between said reversible thermosensitive recording member and said adhesive layer.
- 10. The reversible thermosensitive recording card as claimed in claims 7 or 8, wherein said adhesive layer comprises at least two adhesive layers, and an intermediate support material which is interposed between said adhesive layers.
- 11. The reversible thermosensitive recording card as claimed in claims 7 or 8, wherein said adhesive layer comprises an air-containing vacant portion therein free of adhesive agent, through which light passes, and which serves as a display area.
- 12. The reversible thermosensitive recording card as claimed in claims 7 or 8, wherein said adhesive layer comprises an adhesive agent having cushioning properties.
- 13. The reversible thermosensitive recording card as claimed in claims 7 or 8, further comprising a magnetic recording layer.
- 14. The reversible thermosensitive recording card as claimed in claims 7 or 8, further comprising a reflection layer for improving the contrast of formed images.
- 15. The reversible thermosensitive recording card as claimed in claims 7 or 8, further comprising a coloring layer for improving the contrast of formed images.
- 16. The reversible thermosensitive recording card as claimed in claims 7 or 8, wherein the surface of said reversible thermosensitive recording member is positioned higher than the surface of said label receiving material.
