DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label recording medium having a release paper on the back surface and capable of peeling off the release paper and attaching a portion formed with an image or the like to a desired article. The present invention relates to a label recording medium suitable for use in an ink jet recording system.

[0002]

2. Description of the Related Art Generally, a label recording medium (label sheet) on which an image is formed or a label body on which an image can be formed (in this specification, a portion to be attached to an object is referred to as a "label body". ) And a release paper adhered to the back side of the label body. As is well known, in a label recording medium, by peeling off a release paper on the back side, an adhesive layer of a label body is exposed and can be attached to a desired location.

As described above, a label recording medium having an ink-receiving layer capable of forming an image on a label body is easy to use since an image can be easily formed using an ink jet printer and the formed image can be freely selected. Conventionally, it is commercially available as a label sheet for ink jet recording.

[0004] Such a label recording medium is required to be easily peelable (easily peelable) because the release paper must be peeled off at the time of use. So, for example,
In many cases, an easy-peeling means such as a half-cut is formed on a base material (label body) or release paper (in the present specification, “half-cut” means a cut structure in a thickness direction of release paper or the like). Can be seen. In the case where the easy peeling means such as the half cut is formed, for example, by slightly deforming the portion where the easy peeling means is formed or the vicinity thereof, a knob portion for separating the label body and the release paper can be easily formed. It is easy to use because it can be formed.

On the other hand, in recent years, image forming apparatuses such as ink jet printers capable of forming high-quality color images have become widespread. Accordingly, various high-quality images can be formed extremely easily on a label recording medium using an ink jet printer.

[0006] Among the recording media for labels used in ink jet printers and the like, the configuration in which the easy-peeling means is formed particularly on the release paper does not cause the formed image to be divided by the easy-peeling means, and is good. Because it can exhibit excellent peeling performance, there is no restriction on the image forming area such as the image size formed by the user, and its usability as a label recording medium is superior to that in which easy peeling means is provided on the label body side ing.

The label recording medium provided with the easy peeling means on the release paper side will be described with reference to FIG. 4 and FIG. 4 is a schematic sectional view showing a portion along the line ZZ of the label recording medium shown in FIG. 5 and a punch cutter, and FIG. 5 is a plan view of the label recording medium.

As shown in FIG. 5, the rectangular label recording medium 20 is formed with a half cut 26 as an easy peeling means along the width direction thereof. As shown in FIG. 4, the label recording medium 20 has an image forming layer 22 on the front side (upper side in the figure) of the base material 23, while the back side (lower side in the figure)
A label body 27 having an adhesive layer 24, and a base sheet 25 provided on the outside of the adhesive layer 24 so as to be detachable from the label body 27. The base sheet 25 is provided with a half cut 26 formed by the punching cutter 30 in the thickness direction thereof, for example, as a cut having a certain depth.

When separating the label body 27 as the base material and the base sheet 25 as the release paper, the portion where the half cut 26 as the easy-peeling means is formed or its vicinity, as shown in FIG. Curve (arrow X direction)
As a result, a separation start portion 25a in which the label body 27 and the base sheet 25 have started separating from the half cut 26 is formed. And this separation starting part 25
Since a can be picked with a finger, the starting operation of peeling can be facilitated.

[0010]

In the label recording medium shown in FIG. 5, the base sheet 25 is formed by the above peeling operation.
Can be easily peeled off from the label body 27, but there is a problem that in the ink receiving layer 22 on the base material 23, image unevenness occurs in the pressed portion B corresponding to the half cut 26 of the base sheet 25.

That is, the half cut 26 is formed in a state where the base sheet 25 and the label main body 27 are joined, and this half cut 26 is formed by the punch cutter 30 which applies a force in the thickness direction of the label recording medium 20. In order to perform the pressing (the ink receiving layer side is appropriately supported by supporting means at the time of pressing), the cutter 30 and the cutter 30 are pressed.
Between the support means (not shown) arranged on the opposite side,
The ink receiving layer 22, the substrate 23, and the adhesive layer 24
(The pressurized portion B is compressed) by the pressing force.

As a result, the ink receiving layer 22 may be deformed in appearance, and even if it is not deformed in appearance, its structure may be destroyed inside.

In the state where the ink receiving layer 22 is damaged in some way along the half cut 26, the damaged portion (the lower portion corresponding to the half cut 26) is formed as shown in FIG. When the image area A is located, the pressurized portion B in which the half cut 26 is formed has, for example, a difference in ink permeability compared to other normal portions (portions other than the pressurized portion), or a slight difference. As a result, the reflection of light may be affected by such a deformation, resulting in image unevenness.
