Abstract

A label manufacturing method including: applying an adhesive to a base sheet to form an adhesive layer; applying an acrylate-based bonding adhesive to part of the adhesive layer to cure the adhesive layer so as to form a cured portion; and cutting the cured portion to define labels. A label having an adhesive layer 12 is laminated on a base sheet 13 . A part of the adhesive layer 12 is cured to form a cured portion 14 , wherein the cured portion 14 is cured by an acrylate-based bonding adhesive for enabling cutting labels off the laminated base sheet.

First claim

The invention claimed is:

1. A label manufacturing method comprising:
applying a first adhesive to a base sheet to form an adhesive layer;
partially applying a second adhesive which is an acrylate-based bonding adhesive to the applied adhesive layer, on the same side of the base sheet as the adhesive layer, to form a mixture of the first adhesive and the second adhesive;
curing the mixture so as to form a cured portion where the second adhesive has been applied; and
cutting the cured portion and the base sheet to define a separated label.

2. The label manufacturing method according to claim 1 , further comprising:
peeling-off waste by removing an unnecessary portion of the base sheet outward of the separated label.

3. The label manufacturing method according to claim 1 , wherein the second adhesive is a radical-polymerizable ultraviolet ray-curable composition.

4. The label manufacturing method according to claim 1 , wherein
the cured portion has a thickness between 1 μm and 30 μm.

5. The label manufacturing method according to claim 1 , further comprising forming the cured portion on a line to be subsequently cut in the cutting step and in a vicinity of the line.

6. The label manufacturing method according to claim 1 , wherein the cured portion is formed in a range of 0.1 mm to 3 mm in width including a line to be cut in the cutting step.

7. The label manufacturing method according to claim 1 , wherein the first and second adhesives are different adhesives.

8. The label manufacturing method according to claim 1 , wherein the cured portion is formed along an edge of the base sheet.

9. The label manufacturing method according to claim 1 , wherein the cured portion is formed along a line spaced from an edge of the base sheet.

10. The label manufacturing method according to claim 1 , wherein the first adhesive is an adhesive based on synthetic rubber or natural rubber.

11. The label manufacturing method according to claim 1 , further including:
attaching a label separator to the adhesive layer, wherein the separated label is removably attached to the label separator.

12. A label manufacturing method comprising:
applying a first adhesive to a base sheet to form an adhesive layer;
partially applying a second adhesive which is an acrylate-based bonding adhesive to the applied adhesive layer, on the same side of the base sheet as the adhesive layer, to form a mixture of the first adhesive and the second adhesive;
irradiating the acrylate-based bonding adhesive applied to the part of the adhesive layer with an ultraviolet ray; and
cutting the base sheet where the acrylate-based bonding adhesive has been applied to define a separated label.

13. The label manufacturing method according to claim 12 , further comprising:
peeling-off waste by removing an unnecessary portion of the base sheet outward of the separated label.

14. The label manufacturing method according to claim 12 , wherein the acrylate-based bonding adhesive is a radical-polymerizable ultraviolet ray-curable composition.

15. The label manufacturing method according to claim 12 , wherein the first and second adhesives are different adhesives.

16. The label manufacturing method according to claim 12 , wherein the first adhesive is an adhesive based on synthetic rubber or natural rubber.

17. The label manufacturing method according to claim 12 , further including:
attaching a label separator to the adhesive layer, wherein the separated label is removably attached to the label separator.
