Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label without a backing sheet, and more particularly to a label without a backing sheet which is suitable for recording and stamping with a writing instrument, thermal transfer, and printer printing by an ink jet system.

[0002]

2. Description of the Related Art A conventional general label is formed by sequentially laminating a printing paper, an adhesive, and a backing paper (release paper). However, since the mounting paper is peeled off when the label is used, it is used.
There is a problem that the mount is discarded as garbage after use.

[0003] Therefore, a label without a mount, commonly called a label without a mount, has been developed for the purpose of reducing waste and saving resources.

FIG. 3 is a cross-sectional view of a conventional label 1 without a mount, in a width direction thereof.
A long strip-shaped label substrate 2 is provided with a release agent layer 3 on one surface (front surface) and an adhesive layer 4 (pressure-sensitive adhesive layer) on the other surface (back surface). Wrapped around.

Therefore, even when the pressure-sensitive adhesive layer 4 of the label substrate 2 on the outer peripheral side overlaps the release agent layer 3 of the label substrate 2 on the inner peripheral side when wound up in a roll shape, each of them is adhered to each other. Since they can be used in a strip shape without using each other, there is no need to provide the mount 5 (virtual line in the figure) below the adhesive layer 4.

[0006] The label 1 without a backing sheet is cut by a cutter (not shown) for each unit, or cut off at a preformed perforation (not shown) or the like.

[0007] In the label 1 without the backing having such a configuration, in order to display a predetermined content on the front side of the label substrate 2, the label substrate 2 is not produced at the stage of manufacturing the label 1 without the backing.
Is subjected to pre-printing 6 in advance, and then the release agent layer 3 is applied.

After the release agent layer 3 is applied to the label base material 2, that is, after the label-less label 1 is manufactured, the label user can display the variable information of a predetermined content by using FIGS. 4 and 5. The configuration is as shown in FIG.

FIG. 4 is a cross-sectional view showing the operation of printing on the label 1 without the backing paper of FIG. 3, in which the thermal transfer ink of the thermal transfer ribbon 8 is heated by the thermal head 7 of the thermal transfer printer so that the thermal transfer ink of the thermal transfer ribbon 8 is printed. Side (release agent layer 3
To the transfer side 9).

FIG. 5 shows a conventional thermal label 1 without a backing paper.
FIG. 2 is a cross-sectional view of the label 0 (label without mount). In a thermal label 10 without mount, a thermal coloring layer 11 is formed on an upper layer of the label base material 2.

A thermal label 1 without a backing sheet having such a configuration.
0, the thermal head 7 of the thermal printer
A predetermined portion of the thermal coloring layer 11 is colored by the heating of the predetermined pattern by the above, and coloring printing 12 can be performed.

The printing by the thermal transfer method (transfer printing 9 in FIG. 4) itself has excellent print storability and various resistances, but the thermal transfer ink is a general-purpose release agent such as a thermosetting release agent or an ultraviolet curing type. There is a problem that transfer to the surface of the release agent or the like (that is, the release agent layer 3) is difficult.

In order to transfer the thermal transfer ink to the surface of the release agent layer 3, it is necessary to use a heavy release type release agent capable of transferring the thermal transfer ink, or to use a special thermal transfer ink. However,
The heavy release type release agent has a problem that the adhesive strength of the adhesive of the adhesive layer 4 combined therewith is restricted. Accordingly, the label 1 without a backing sheet for performing the transfer printing 9 on the surface of the release agent layer 3 generally has the weak adhesive layer 4 having a weak adhesive force, and the diversity as the adhesive performance is not improved. poor. Further, the types of special thermal transfer inks are limited, and a desired printing resistance may not be obtained in some cases.

On the other hand, the printing by the thermal coloring method (the coloring printing 12 in FIG. 5) itself can be obtained relatively easily and easily, but the thermal coloring layer 11 is easily affected by the surrounding temperature and humidity and has a good storage property. In addition, there is a problem of poor resistance.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is capable of recording and stamping with a writing instrument, printer printing of variable information by thermal transfer and an ink jet method, and a label base material and a release agent. It is an object of the present invention to provide a label without a backing sheet that can have a variety of materials for the layer and the pressure-sensitive adhesive layer, and has excellent storability and durability.

[0016]

According to the present invention, there is provided, according to the present invention, a label without a backing sheet having a strip-shaped label base material having a release agent layer formed on one surface and an adhesive layer formed on the other surface. Wherein the label substrate has a strength such that at least one surface does not peel or tear when the pressure-sensitive adhesive to be used is peeled off, and the one surface (surface) has the peeling property. A label without a backing sheet is provided, in which a release area by an adhesive layer and a print area in which the release agent layer is not formed are provided, and an adhesive area by the adhesive layer is provided on the other surface (back surface) over the entire surface. Is done.

It is preferable that the width of the printing area is wider than the width of the adhesive area.

In the label without mount according to the present invention,
It is possible to reliably and easily perform recording and marking with a normal writing instrument, thermal transfer, and printer printing by an ink jet method in a print area without a release agent layer.

Further, since printing can be performed by the thermal transfer method, any material such as a film, paper, a laminate thereof, or a label material of a composite material can be selected as the material of the label substrate.

[0020] Thus, the label without mount has excellent storage stability and durability.

The adhesive layer also has a slight adhesion, a weak adhesion,
It is possible to arbitrarily select from strong adhesion or ultra-strong adhesion, and it is possible to ensure a variety of adhesive performances as a label without a mount.

The release performance of the release agent layer can be selected according to the pressure-sensitive adhesive layer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a label 20 without a backing sheet according to an embodiment of the present invention will be described with reference to FIGS. However, the same parts as those in FIGS. 3 to 5 are denoted by the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 is a perspective view of the label 20 without a mount, and FIG. 2 is a cross-sectional view taken along the line II-II of FIG.
1 and a printing area 22 provided in the middle of the peeling area 21
And an adhesive region 23 on the back side of the label substrate 2.

The release area 21 is constituted by a release agent layer coated with a release agent. The print area 22 is not coated with a release agent.

The adhesive area 23 is constituted by an adhesive layer coated with an adhesive.

Each of the printing areas 22 is provided at the center of the label base material 2 and is disposed at equal intervals along the length direction and in parallel with both sides. When wound in a shape, the peeling region 21 and the printing region 2
2 comes to face the adhesive region 23.

As the label substrate 2, a conventionally known film, paper, or a laminate or composite material thereof can be used. However, since the print area 22 having no release agent layer and the adhesive area 23 are in direct contact with each other. It is necessary that at least the surface constituting the print area 22 has a strength that does not peel or tear when the label 20 without a mount is unwound.

Although not shown, if the printing areas 22 and the peeling areas 21 are arranged symmetrically and alternately in the width direction of the label base material 2, the label 20 without the backing paper can be balanced in the width direction as a whole. It becomes a layered structure, and it is possible to avoid a winding deviation when wound in a roll shape.

The width and arrangement of the peeling area 21 and the printing area 22 can be determined from the area and layout required for transfer printing.

Here, the width of the peeling area 21 is
It is desirable that the width be larger than the width of 2.

That is, the width W of the print area 22 shown in FIG.
1. By satisfying the relationship of W1 / W2 <0.5 between the total width W2 of the label base material 2, the label 20 can be smoothly unwound as the mount-less label 20 and run. When there are a plurality of print areas 22 in the width direction of the label base material, the total width of the plurality of places is W1.

In the label 20 without the backing sheet having such a configuration, the label is loaded into an arbitrary thermal transfer printer (not shown),
A thermal transfer ribbon can be aligned with the print area 22 and thermal transfer printing can be performed by a thermal head.

The thermal transfer ink can be freely selected according to the required characteristics of printing.

As shown in FIG. 2, a preprint 6 may be provided in advance on the front side of the label substrate 2 as in FIG. The world print 6 has a print area 22 and a peel area 21.
Independent of (i.e., for example, over both).

In the present invention, the label 2 without the backing sheet is used.
The number, width, formation position, shape, pattern, and the like of the peeling region 21, the printing region 22, and the adhesive region 23 are not limited to zero, depending on the printing position and the like.

[0037]

As described in detail above, the label without mount of the present invention has a printing area without a release agent layer on the surface (one side) of the label substrate and an adhesive area on the back side (the other side). Therefore, it is possible to record and seal with a writing instrument on a printing area, and perform printer printing by thermal transfer or an ink jet method.

Further, there are a wide selection of label substrates, release agents, pressure-sensitive adhesives, and thermal transfer inks, and characteristics suitable for the purpose, such as storage stability and resistance, can be secured.
