Description

  The present invention relates to an information recording adhesive label, an information recording adhesive sheet, and an information recording adhesive sheet with a release sheet used for managing articles. The present invention also relates to an article with an information recording adhesive sheet capable of electronically recording information without contact. Furthermore, it is related with the usage method of the said adhesive sheet for information recording.

In recent years, RFID (Radio Frequency Identification) systems that perform writing and reading of information in a non-contact state are becoming widespread in delivery and inventory management.
Normally, a slip in which an IC inlet having an IC and an antenna is incorporated is used as an interface of the RFID system.

By the way, the IC or IC inlet for the RFID system is required to be recoverable from the viewpoint of resource saving. In response to this requirement, Patent Document 1 proposes a form with a built-in IC inlet in which a portion including the IC inlet can be separated.
However, the form with a built-in IC inlet described in Patent Document 1 collects and reuses the IC or the IC inlet itself. That is, since the form of a slip such as a form or a delivery slip is not reused, the portion other than the IC or the IC inlet has been discarded.
Therefore, Patent Document 2 proposes a delivery tag with an IC tag in which an IC tag including an IC inlet is detachably attached to a delivery / receipt slip so that it can be reused.

The information is recorded so as to be visually recognized using a rewrite printer of a thermal recording system (see FIGS. 3A and 3B). The visually recognizable information recorded here is, for example, characters, symbols, designs, barcodes, QR codes, and the like.
Further, the information on the article is electronically recorded on the IC of the IC inlet 13 by the rewrite printer.

Next, the second second release sheet 30 is peeled off from the information recording pressure-sensitive adhesive sheet 1 with a release sheet on which information is recorded so as to be visible on the surface of the surface base material 11, and the information recording pressure-sensitive adhesive sheet 1 a is removed. obtain.
Next, the information recording pressure-sensitive adhesive sheet 1a is adhered to the article 40 by the second pressure-sensitive adhesive layer 22 (see FIG. 3C), and the information recorded electronically on the IC of the information recording pressure-sensitive adhesive sheet 1a is recorded. Based on this, the article 40 is managed.
As a management method, the electronically recorded information recorded in the IC is read using a non-contact type writing / reading device, and the delivery and inventory management of the articles 40 are performed based on the information. Further, the article 40 can be managed based on information recorded in the recording layer 11b so as to be visible.

After the completion of management, the pressure-sensitive adhesive label 10 of the information recording pressure-sensitive adhesive sheet 1a attached to the article 40 is peeled off and collected from the article-attached pressure-sensitive adhesive sheet 20 (see FIGS. 3D and 3E). The remaining adhesive sheet 20 for attaching an article may remain attached to the article 40 or may be peeled off.
Next, as shown in (e) and (f) of FIG. 3, a new second release sheet 30 is attached to a new pressure-sensitive adhesive sheet 20 that is peeled and recovered, and a second pressure-sensitive adhesive. The article-attaching adhesive sheet 1b with a new release sheet laminated by the layer 22 is attached so that the first adhesive layer 12b and the first release sheet 21 are in contact with each other. The product thus obtained has the same configuration as the information recording pressure-sensitive adhesive sheet 1 with a release sheet.
Next, the information recorded on the recording layer 11b of the obtained information recording pressure-sensitive adhesive sheet 1 with a release sheet is erasable by using a rewrite printer that can write to the IC of the IC inlet 13, and recorded. The layer 11b can be recorded so as to be visible. At the same time, the information electronically recorded on the IC of the IC inlet 13 is erased using the rewrite printer.
The adhesive label 10 is repeatedly used in the management of the article 40 by repeating the above steps.

  As described above, by using the release sheet-attached information recording pressure-sensitive adhesive sheet 1 provided with the pressure-sensitive adhesive label 10, the pressure-sensitive adhesive label 10 incorporating the IC inlet 13 can be repeatedly reused without being subjected to pressure-sensitive adhesive processing after peeling. .

For example, in the method of using the pressure-sensitive adhesive sheet for information recording of the present invention, the recording layer 11b may not be a reversible thermosensitive recording layer, for example, an irreversible thermosensitive recording layer, a pressure sensitive recording layer, an inkjet recording layer, a sublimation transfer. A recording layer, a thermal transfer recording layer, a recording medium capable of recording an image by an optical writing method, or a recording medium capable of printing / erasing with a laser may be used. A method for recording information so as to be visible is appropriately selected according to the type of the recording layer 11b. However, since the reversible thermosensitive recording layer or the optically rewritable recording medium has an advantage that information once recorded can be easily erased, the recording layer 11b is preferably a reversible thermosensitive recording layer or an optically rewritable recording medium.
In the method of using the information recording pressure-sensitive adhesive sheet of the present invention, it is not necessary to record information on the information recording pressure-sensitive adhesive sheet 1a so as to be visible. When the information is not recorded so as to be visible, the article 40 is managed by the information electronically recorded on the IC of the IC inlet 13.
Further, when the surface substrate 11 does not have a recording layer, the information may not be recorded so as to be visible, or may be recorded by ink jet recording or the like.
Information may be recorded on the IC using a non-contact writing / reading device after the information recording adhesive sheet 1a is attached to the article 40.
Further, it is not necessary to perform writing and erasing of information on the IC separately, and they may be performed simultaneously.

When using the wound body of the information recording pressure-sensitive adhesive sheet 1a, the information recording pressure-sensitive adhesive sheet 1a is fed out from the wound body of the information recording pressure-sensitive adhesive sheet 1a and pasted on the article 40 by the exposed second pressure-sensitive adhesive layer 22.
