Description

  The present invention relates to a mountless label on which printing is performed by thermal transfer using an ink ribbon.

Conventionally, a label without a mount that does not use a mount (also called a release sheet or a separator) has been proposed and put into practical use (for example, Patent Document 1).
The label without a mount is shipped in a state of being wound in a roll shape with the adhesive on the back surface being in contact with the surface of the label. Therefore, a release agent layer is formed on the label surface so that the pressure-sensitive adhesive is easily peeled off from the label surface.
In the conventional label without a mount, since the release agent layer is formed on the label surface, the ink adheres on the label surface. Therefore, there has been a problem that additional printing on the label surface cannot be performed, or even if printing is performed, the printing is peeled off.
Therefore, in above-mentioned patent document 1, it printed on the base material beforehand and was used for the use which does not perform the additional printing after label completion.

  There is also a demand to perform additional printing on a label without a mount. Therefore, in Patent Document 2, a base material is formed of thermal paper, and additional printing can be performed on a label without a mount.

JP 2002-189417 A JP 2013-134284 A

  The thermal method has low storage stability, heat resistance, and weather resistance, and there has been a demand to perform thermal transfer printing using an ink ribbon. However, conventionally, there are no mountless labels in which frames and detection marks (eye marks) are printed on both the front and back surfaces in advance, and additional printing using ink ribbons does not exist. .

  An object of the present invention is to provide a label without a mount, which can be printed in advance on both the front and back surfaces, and which can perform thermal transfer printing.

  The present invention solves the above problems by the following means.

  The invention of claim 1 is characterized in that the base layer (11), the first printing part (12) provided on one surface of the base material layer, and the first printing part are further covered. An acrylic release agent layer (14) formed on one surface of the material layer, a second printing section (13) applied on the other surface of the base material layer, and the second printing section A non-backing label (10) comprising: a releasable pressure-sensitive adhesive layer (15) formed on the other surface of the base material layer so as to cover.

  The invention according to claim 2 is the label without a mount according to claim 1, wherein both the first printing unit (12) and the second printing unit (13) are formed of water-based ink. Is a mountless label (10) characterized by the following.

  The invention of claim 3 is the label without a mount according to claim 1 or claim 2, wherein the label without the mount can be printed on the acrylic release agent layer (14) by thermal transfer. It is a featureless label (10).

  According to the present invention, it is possible to provide a non-mounting label that can be printed in advance on both the front and back surfaces and that can perform thermal transfer printing.

It is sectional drawing which shows embodiment of the label 10 without a mount by this invention. It is sectional drawing which shows the manufacturing process of the label 10 without the mount of this embodiment.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

(Embodiment)
FIG. 1 is a cross-sectional view showing an embodiment of a mountless label 10 according to the present invention.
In addition, each figure shown below including FIG. 1 is the figure shown typically, and the magnitude | size and shape of each part are exaggerated suitably for easy understanding.
In the following description, specific numerical values, shapes, materials, and the like are shown and described, but these can be changed as appropriate.

  The mountless label 10 includes a base material layer 11, a first printing unit 12, a second printing unit 13, an acrylic release agent layer 14, an adhesive layer 15, and a cutting notch 16. ing.

  The base material layer 11 is formed of a strip-shaped coated paper.

  The first printing unit 12 is applied to the surface of the base material layer 11. The first printing unit 12 is formed of water-based ink. As display contents by the first printing unit 12, for example, a label frame, a product name, a company name, and the like may be appropriately selected as necessary.

  The second printing unit 13 is provided on the back surface of the base material layer 11. Similarly to the first printing unit 12, the second printing unit 13 is also formed of water-based ink. The display content of the second printing unit 13 may be a detection mark (eye mark) for detecting one unit of label when a label with a mount is run by a label printer or an automatic sticking machine.

  Here, the reason why the first printing unit 12 and the second printing unit 13 are formed with water-based ink will be described. If the 1st printing part 12 and the 2nd printing part 13 are formed with a water-based ink, the adhesiveness with the acrylic release agent layer 14 and the adhesive layer 15 will become favorable. Therefore, by forming the first printing unit 12 and the second printing unit 13 with water-based ink, the acrylic release agent layer 14 on the first printing unit 12 is dropped and the second printing unit 13 is removed. Can be prevented from falling off.

The acrylic release agent layer 14 is formed on the surface of the base material layer 11 so as to further cover the first printing unit 12. On the other hand, the acrylic release agent layer 14 of the present embodiment uses Pyroyl HT manufactured by Yushi Co., Ltd.
Unlike the conventionally used silicone resin-based or fluororesin-based release agent layer, the acrylic release agent layer 14 has a good ink ribbon. As a result, the label 10 having no mount according to the present embodiment can additionally print information such as a barcode, price, date and time using a label printer (not shown). As an ink ribbon used for this printing, a semi-resin thermal transfer ink ribbon using a solvent-based ink may be used.

  In this specification and claims, as a normal usage by those skilled in the art, the display of fixed information by a printing press at the time of label production is set to “printing”, and information output that is additionally performed by a thermal printer or the like is output. Used as “printing”. However, as described above, “printing” refers to the output of information by a thermal printer or the like, and includes not only the output of characters but also the output of graphics such as barcodes and images.

  The pressure-sensitive adhesive layer 15 is formed of a microsphere type pressure-sensitive adhesive having removability. Even if the pressure-sensitive adhesive layer 15 is applied to smooth paper, it can be peeled cleanly, and can be applied many times.

  The cutting notch 16 is a notch for separating the label for each unit. The cutting notches 16 may be formed as perforations in the width direction of the non-mounting label 10, for example.

FIG. 2 is a cross-sectional view showing the manufacturing process of the mountless label 10 of the present embodiment.
First, as shown in FIG. 2A, the first printing unit 12 is printed on the surface of the base material layer 11, and the second printing unit 13 is printed on the back surface of the base material layer 11. As described above, water-based ink is used for this printing.

  Next, as shown in FIG. 2B, an acrylic release agent layer 14 is formed by pyroyl HT on the surface of the base material layer 11 so as to cover the first printing portion 12. The acrylic release agent layer 14 is UV cured after being applied on the surface of the base material layer 11.

  Next, as shown in FIG. 2C, a cutting notch 16 is formed by a technique such as die cutting.

  Finally, the pressure-sensitive adhesive layer 15 is applied on the back surface of the base material layer 11 so as to cover the second printing section 13, thereby completing the label 10 without the mount (FIG. 1). Note that the completed non-mounting label 10 may be further processed into a form that can be shipped by being cut in a slit process or wound in a small volume.

  As described above, according to this embodiment, the label 10 without mount is preliminarily printed on the base material layer 11 using water-based ink, and the acrylic release agent layer 14 is formed on the surface side. Therefore, the label 10 without mount can prevent the acrylic release agent layer 14 from dropping off in the first printing unit 12 and the adhesive layer 15 from dropping off from the second printing unit 13. Further, the non-mounting label 10 can be additionally printed by thermal transfer printing using an ink ribbon. Therefore, the non-mounting label 10 of the present embodiment is superior in storage stability, heat resistance, and weather resistance to the non-mounting label by the conventional thermal method. Further, the mountless label 10 of the present embodiment has no mount to be discarded as in the case of the conventional mountless label, and can be used as an environmentally friendly label that contributes to resource saving.
