JPH11288222A - Linerless label base material - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a linerless label continuous body which prevents a release agent from penetrating a label base material by resolving the problem that the release agent like a silicone penetrates the label base material (slick paper) to bring about a defect that a peelable layer cannot be formed at the time of directly applying the release agent on the surface of the label base material. SOLUTION: The rear face of a label base material (slick paper) 1 is coated with an adhesive layer 2, and the front face of the label base material 1 is coated with a transparent high polymer material 3 (a resin hardened by ultraviolet rays and a hot melt adhesive) to be a reception layer, and the surface of this high polymer material 3 is coated with a release agent 6 like a silicone. Since the transparent high polymer material 3 forms a thin film on the label base material 1, characters, graphics, etc., printed on this surface are not blurred and are made vivid. Further, an effect that the print on the surface of the label base material 1 can be distinctly confirmed is given because the high polymer material 3 made transparent is formed on the surface of the label base material 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label base material without a band-shaped backing sheet, that is, a label base material for a linerless, and more particularly to a label base material of a general seal (high quality paper) which is not thermal paper.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. Hei 6-340190 (adhesive sheet for printing and a method for producing the same) can be cited as an example of such a label-less label base material. This configuration has an adhesive layer on the back side of the belt-shaped base sheet (label base material),
A printing layer is provided on the surface side, and a release agent layer of silicon or the like having a high release effect is provided directly on this surface, and the adhesive layer and the release layer are wound in a roll shape in parallel with each other. .

[0003]

However, when a release agent such as silicon is directly applied to the surface of the label substrate as described above, the release layer penetrates into the label substrate (high quality paper), and the release layer is formed. There is a defect that cannot be formed and uses a large amount of release layer (silicon). An object of the present invention is to provide a linerless label base material in which a release agent does not penetrate into the label base material.

[0004]

In the label base material for linerless of the present invention, a pressure-sensitive adhesive layer 2 is provided on the back side of the label base material 1, and a transparent polymer serving as a receptor layer is formed on the front side. The method is characterized in that the substance 3 is applied, and a release agent is applied to the surface. The transparent polymer substance 3 is an ultraviolet curable resin or a hot melt adhesive.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. A detection mark 5 for detecting a label pitch is provided on the back surface of the label base material (high quality paper) 1, and an adhesive layer 2 is provided on the detection mark 5 and the entire back surface of the label base material 1. The pressure-sensitive adhesive layer 2 may be pressure-sensitive or heat-sensitive, and is not limited.

Further, after a transparent polymer material 3 such as an ultraviolet-curable resin or a hot-melt adhesive serving as a receiving layer is applied to the surface of the label substrate 1, a carbon ribbon is applied to the surface of the polymer material 3. And the like, and a release layer 6 of silicon or the like is applied on the uppermost surface.

[0007]

According to the present invention, as described above, an adhesive is applied to the back side of the label substrate, and a transparent polymer substance (ultraviolet curable resin, hot melt adhesive) is applied to the front side. Since the release agent is applied to the surface of the polymer substance, the release substance such as silicon on the uppermost layer does not permeate the label substrate because the release substance is formed as the receiving layer. Therefore, since the transparent polymer substance forms a thin film on the label base material, characters, figures, and the like printed on the surface do not blur and are clear. Further, since the transparent polymer material is formed on the surface side of the label base material, the printing on the surface of the label base material can be clearly confirmed.
