Abstract

PURPOSE:To obtain excellent preservability and to reduce the cost by arranging an adhesive layer on a transparent film on the side of its coloring material coating surface. CONSTITUTION:This label consists of the transparent film 1, a thermal coloring agent layer 2, the adhesive layer 3, and releasing paper 4. Namely, the film 1 coated with a thermal coloring agent 2 on one side is made to pass through a thermal head to be colored, the films 1 on which dots are formed is conveyed between rollers, and a both-side adhesive tape to be a self-adhesive 3 and the releasing paper 4, respectively is stuck. Namely, the thermal coloring agent layer 2 colors with heat from the thermal head and its coloring area extends to the boundary of the transparent film 1, so the area can be recognized even from the side of the transparent film 1. Further, the thermal coloring agent layer 2 is protected by the transparent film 1, so the layer is hardly affected by heat, external force, etc., from the surface and the preservability is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label for a label printer, and more particularly to a label for a label printer having good storage stability.

[0002]

2. Description of the Related Art Conventional label printer labels include (1) a type in which an adhesive is applied to the back side of thermal paper (2) a type in which ink is transferred to a label in which an adhesive is applied to one side (3) a transparent film There were three types: a type that transfers ink and a double-sided tape is attached.

[0003]

However, in the above-mentioned prior art, (1) the readability of characters is deteriorated by heat or chemicals.

(2) The ink is peeled off by a physical external force, and the readability of characters is deteriorated.

(3) Since the ink is transferred, the structure is complicated and expensive.

[0006] There was a problem.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a label for a label printer having good storage stability at low cost.

[0008]

A label for a label printer according to the present invention comprises a transparent film having a thermochromic material coated on one side and an adhesive layer, and the adhesive layer is arranged on the thermochromic material coated surface side of the transparent film. It is characterized by the structure.

The thermochromic material is colored, and the thermochromic material is transparent and the adhesive layer is colored.

[0010]

In the label printer constructed as described above, since the double-sided tape is attached to the color developing side of the transparent film which is directly colored by the thermal head, the printer line mechanism is simple and the printing surface is protected by the film.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a cross-sectional view of the label after printing, and FIG. 2 is an explanatory view of a printer that creates the label.
1 is a transparent film, 2 is a thermochromic agent layer, 3 is an adhesive layer, 4
Is a release paper, 5 is a transparent film (hereinafter abbreviated as film) coated with a thermal color developing agent, 6 is a double-sided tape, 7 is a thermal head, 8 is a platen, 9 is a feed roller, and 10 is a driven roller.

Next, the outline of the printer will be described. When the film 5 having the thermal color developing agent applied to the D surface passes between the thermal heads 7 pressed by the platen 8, a color is developed by the thermal head 7 from a control circuit (not shown), and dots are formed on the D surface of the film 5. It is formed. The film 5 on which dots are formed is conveyed between a feed roller 9 driven by a motor (not shown) and a driven roller 10 that freely rotates. The double-sided tape 6 is installed such that the A side is an adhesive and the B side is a release paper, and the feed roller 9 is a driven roller 10.
It is affixed to the film 5 by being pressed against.
The film 5 to which the double-sided tape 6 is attached is the feeding roller 9
Is formed of a high friction material such as rubber, and is conveyed in the direction of arrow C by the frictional force generated between the film 5 and the feed roller 9. Dots are formed on the thermochromic agent applied to the D side of the film 5 and a double-sided tape is attached to complete the label.

In the label thus produced, the thermal color former layer 2 is colored by the heat applied by the thermal head 7,
The coloring area is not limited to the thermal coloring agent layer and extends to the boundary with the transparent film 1, so that the coloring can be recognized from the transparent film side.

Characters that are mirror-printed from the heat color former side are normal characters from the transparent film side, which is the back side.
Normal characters can be seen when pasted as a label. Since the thermal color former layer 2 is protected by the transparent film 1, it is less susceptible to heat and external force from the surface and the storage stability is improved. Furthermore, by using a resin such as polyethylene for the transparent film, the thermocoloring agent can be protected from water, chemicals and the like.

Although not mentioned in this embodiment, a label cassette which can be handled easily can be constructed by housing at least the film 5 and the double-sided tape 6 in one case. In addition, by coloring the thermocoloring agent, when the label is viewed from the transparent film side, it is possible to recognize the state in which characters are printed on the color background, and therefore it is possible to produce a colored label. Similarly, a colored label can be produced by combining a transparent thermochromic agent and a colored adhesive layer.

This embodiment describes an example in which specular characters are printed from the thermochromic agent side and normal characters are recognized through a transparent film. However, the content to be printed is not limited to characters, but figures, bar codes, etc. Needless to say, it includes such as. Furthermore, although the color of the thermal color former after heating is not mentioned in this embodiment, it is possible to select a character color other than black by appropriately selecting the thermal color former.

[0017]

As described above, according to the present invention, not only is it possible to provide a label having good storability at a low cost, but also an ink ribbon winding mechanism is not required,
There is also an effect that the structure of the printer body can be simplified.
