Description

The present invention relates to a method for manufacturing a perforated label for manufacturing a perforated label to be attached onto a perforated disk such as a CD or DVD using a perforated label substrate. It is characterized in that it can be manufactured easily.

  Conventionally, as a label to be pasted on a perforated disk such as CD or DVD, as shown in FIGS. 1A and 1B, an adhesive layer 12 is provided on one side of a label substrate 11a. In addition, a perforated label 10 having a hole 13 at the center is used.

  Here, in obtaining such a perforated label 10, as shown in FIGS. 2A and 2B, a label substrate 11 is stuck on the release sheet 20 via an adhesive layer 12. The label base material 11 is provided with a cut 14 corresponding to the perforated label 10, leaving the label base material 11a corresponding to the perforated label 10, and the surrounding label base material 11b being attached to the adhesive layer 12. Together with the release sheet 20, the label substrate 11 c corresponding to the hole 13 of the perforated label 10 is left on the release sheet 20, and corresponds to the perforated label 10. A part of the label base material 11 a was peeled off from the release sheet 20 together with the pressure-sensitive adhesive layer 12.

  However, the user leaves the label base material 11a corresponding to the perforated label 10 as described above, and peels the surrounding label base material 11b together with the adhesive layer 12 from the release sheet 20 described above. After that, the part of the label base material 11c corresponding to the hole part 13 of the perforated label 10 is left on the release sheet 20, and the part of the label base material 11a corresponding to the perforated label 10 is used as the adhesive layer 12. It is very troublesome to peel off from the release sheet 20 together with the punched label 10, in particular, leaving the portion of the label base material 11 c corresponding to the hole 13 of the punched label 10 on the release sheet 20. When the part of the label base material 11a corresponding to the label layer 11a is peeled from the release sheet 20 together with the pressure-sensitive adhesive layer 12, the part of the label base material 11c corresponding to the hole part 13 corresponds to the holed label 10. Base material 11 There is a problem that is peeled from the release sheet 20 with.

  In recent years, it has also been proposed that a release sheet is provided with a cut so that a perforated label can be easily attached to a perforated disk such as a CD or a DVD (see, for example, Patent Document 1).

  However, even in this case where the release sheet is provided with a cut, it is necessary to separate the label base material around the perforated label and the label base material corresponding to the hole portion from the perforated label. The operation is troublesome, and it is difficult to separate the label base material corresponding to the hole portion from the perforated label well.

In addition, in the above, in order to eliminate such work for the user, it is also shown that only the perforated label is attached to the release sheet, but the label base material around the perforated label and The method for separating the label base material corresponding to the hole part in advance is not particularly shown, and in order to attach only the perforated label to the release sheet, the same problem as in the above case still exists. did.

  An object of the present invention is to solve the above-described problems in obtaining a perforated label to be stuck on a perforated disk such as a CD or a DVD. The label substrate corresponding to the surrounding label substrate and the hole portion can be easily separated from the perforated label, so that the perforated label can be easily manufactured and mass-produced. It is an object of the present invention to make it possible to easily stick only a label to a release sheet.

In the method for producing a perforated label according to the present invention, in order to solve the above-described problems, a label base material is pasted on a release sheet via an adhesive layer, and the label substrate together with the adhesive layer. wood cut corresponding to the perforated label provided the label base material of the portion corresponding to the hole of the perforated label is adhered to strongly release sheet than the label substrate other parts AnaAkira Using the label base material, leaving the portion of the label base material corresponding to the hole portion of the perforated label on the release sheet, and peeling the label base material other than the portion corresponding to the hole portion from the release sheet; Separating the label base material around the portion corresponding to the perforated label from the label base material corresponding to the perforated label, and the perforated label separated from the label base material Peel from release sheet and above Through an adhesive layer and to perform the step of attaching to the other release sheet.

  Here, when adhering the portion of the label base material corresponding to the hole portion of the perforated label to the release sheet more strongly than the other portion of the label base material, for example, the hole of the perforated label A part corresponding to the hole part of the perforated label, such as providing an adhesive part using an adhesive having high adhesiveness to the release sheet on at least the part on the release sheet side of the pressure-sensitive adhesive layer in the part corresponding to the part An adhesive part having high adhesiveness to the pressure-sensitive adhesive layer can be provided on the release sheet.

In the method for producing a perforated label according to the present invention, a cut corresponding to the perforated label is provided together with the adhesive layer on the label base material that is adhered to the release sheet via the adhesive layer as described above. In addition, since the portion corresponding to the hole portion of the perforated label is adhered to the release sheet more strongly than the other portion, the portion of the label base material corresponding to the perforated label due to the above-mentioned cut, and the surrounding area When the label base material is separated and the portion corresponding to the hole and the perforated label are separated at the cut, the label base of the portion corresponding to the hole strongly bonded to the release sheet While the material remains on the release sheet, the perforated label becomes peeled from the release sheet together with the adhesive layer.

  For this reason, the label base material corresponding to the hole portion is not peeled off from the release sheet together with the perforated label as in the prior art, and only the perforated label can be easily obtained. , Mass production of perforated labels will be easy.

Then, due to so as to adhere the been perforated label peeled off from the release sheet with the pressure-sensitive adhesive layer as described above to another release sheet, those obtained by attaching only perforated label release sheet Can be easily obtained.

Hereinafter, the manufacturing method of the punched label which concerns on embodiment of this invention is demonstrated concretely based on an accompanying drawing. In addition, the manufacturing method of the punched label which concerns on this invention is not specifically limited to what was shown in the following embodiment, In the range which does not change the summary, it can implement suitably.

  In this embodiment, as shown in FIGS. 3 (A) and 3 (B), it adheres to the surface of a continuous strip-shaped release sheet 20 on which a coating layer 21 made of a material having high releasability such as silicone is formed. An adhesive layer 12 is provided, and a continuous strip-shaped label base material 11 is adhered onto the pressure-sensitive adhesive layer 12, and the label base 11 is bonded to the label base material 11 together with the pressure-sensitive adhesive layer 12 by, for example, die cutting or laser cutting. A cut 14 corresponding to the perforated label 10 is provided so as to extend from the material 11 side to the surface of the release sheet 20 on the pressure-sensitive adhesive layer 12 side.

  In this embodiment, when the adhesive layer 12 is provided on the surface of the continuous strip-shaped release sheet 21 as described above, the portion of the label base material 11c corresponding to the hole 13 of the punched label 10 is peeled off. In order to strongly adhere to the sheet 20, the coating layer 21 made of the above-described material having a high releasability is provided on the part corresponding to the hole 13 and the part in contact with the release sheet 20 in the pressure-sensitive adhesive layer 12. An adhesive portion 12a using an adhesive having high adhesiveness is provided.

  Here, as the adhesive having high adhesiveness with the coating layer 21, for example, a silicone adhesive that is the same kind of adhesive as the coating layer 21, and an acrylic resin and / or a urethane resin are reactive. Adhesives made of a mixture with silicone having the above can be used. In particular, as the acrylic resin and / or urethane resin, it is preferable to use an ultraviolet curable resin that does not require the use of a solvent.

Here, a commercially available ultraviolet curable acrylic resin (T & K TOKA: Best Cure L Carton Medium) and a commercially available reactive silicone (Toray Dow Corning Silicone: BY16-750) have a weight ratio of 85:15. The adhesive mixed in (1) was applied to the surface of a commercially available release sheet 20 (Lintec Corp .: 7K) provided with the coating layer 21 as described above, and cured by irradiation with 45 mJ / cm ² ultraviolet rays. Part and a commercially available acrylic pressure-sensitive adhesive (manufactured by Toyo Ink Manufacturing Co., Ltd .: BPW5320) were applied to the surface of the release sheet 20 provided with the coating layer 21 and dried to obtain an adhesive part for one week. When the adhesive strength of each adhesive portion to the coating layer 21 is compared after being allowed to stand, ultraviolet curable acrylic resin and reactive silicone are mixed. The bonded portion obtained by irradiating the combined adhesive with ultraviolet rays had a bond strength as high as about 22 times that of the bonded portion obtained by applying the acrylic pressure-sensitive adhesive. In addition, when the ultraviolet ray curable acrylic resin and the reactive silicone mixed with the reactive silicone are cured by irradiating with ultraviolet rays as described above, the ultraviolet curable acrylic resin is low. However, when the amount of UV irradiation is too large, it is considered that the reaction between the reactive silicone and the coating layer 21 does not sufficiently occur, and the adhesive strength is reduced in any case. . Therefore, it is preferable that the irradiation amount of ultraviolet rays within a range of ^{15mJ / cm 2 ~60mJ / cm 2} .

  And after providing the cut | interruption 14 corresponding to the perforated label 10 with the adhesive layer 12 with respect to the label base material 11 stuck on the surface of the peeling sheet 20 as mentioned above in FIG. As shown, the label base material 11 provided with a cut 14 corresponding to the perforated label 10 is guided onto the release plate 30 together with the adhesive layer 12 and the release sheet 20, and the advancing direction of the release sheet 20 is changed to the release plate 30. The label base 11 is peeled off from the release sheet 20 together with the pressure-sensitive adhesive layer 12.

  If it does in this way, since the label base material 11c of the part corresponding to the hole part 13 of the perforated label 10 is firmly attached to the peeling sheet 20 by said adhesive part 12a, the hole part of the perforated label 10 The part of the label base material 11c corresponding to 13 remains on the release sheet 20 and is removed together with the release sheet 20, while the other part of the label base material 11 is peeled off together with the adhesive layer 12. The sheet 20 is peeled off.

  Further, the roll-up roller 31 is pressed against the surface of the label base material 11 from which the release sheet 20 has been peeled in this way, so that the label base material 11b around the portion corresponding to the perforated label 10 is formed by the above-mentioned cut 14. While being separated from the perforated label 10 and guided upward, another release sheet 20a guided by the guide plate 32 is guided under the perforated label 10 and the adhesive layer 12 in the perforated label 10 is used. Only the perforated label 10 is stuck on another release sheet 20a, and such operations are sequentially performed to sequentially open the perforated label 10 on another release sheet 20a. Just stick it. Note that the label base material 11a corresponding to the perforated label 10 proceeds in almost the same direction as the traveling direction before the peeling due to its rigidity, etc. immediately after peeling from the peeling sheet 20, and the leading end of the label base 11a hangs down. There is no.

  In this way, the perforated label 10 can be easily manufactured and mass-produced easily, and a product in which only the perforated label 10 is attached to the release sheet 20a can be easily obtained. Become.

  In this embodiment, in order for the label base material 11c corresponding to the hole 13 of the perforated label 10 to be strongly adhered to the release sheet 20, the above-mentioned adhesive is applied to the portion corresponding to the hole 13. An adhesive portion 12a using an adhesive having high adhesiveness to the coating layer 21 made of the material having high peelability is provided in a portion of the agent layer 12 that contacts the release sheet 20. Here, in order to provide the adhesive portion 12a having high adhesiveness on the surface of the release sheet 20 on the side of the coating layer 21 having high peelability, for example, the surface of the release sheet 20 on the side of the coating layer 21 is provided with an ultraviolet curable type. An adhesive in which an acrylic resin and a reactive silicone are mixed is applied at a predetermined interval so as to be approximately the same size as or smaller than the hole portion 13 of the perforated label 10, and UV cured. I will let you. Then, the adhesive layer 12 is provided by, for example, applying an acrylic or rubber adhesive to the release sheet 20 provided with the adhesive portion 12a in such a manner as to cover the adhesive portion 12a. Like that.

  In this embodiment, in order that the label base material 11c corresponding to the hole 13 of the perforated label 10 is strongly adhered to the release sheet 20, the coating layer 21 made of a material having high peelability is used. The adhesive portion 12a using an adhesive having high adhesiveness is provided on the release sheet 20, but the label substrate 11c corresponding to the hole portion 13 of the perforated label 10 is strongly adhered to the release sheet 20. The method of making it is not particularly limited to such a method. For example, as shown in FIG. 5, in the portion corresponding to the hole 13 of the perforated label 10, the coating layer 21 on the surface of the release sheet 20 is eliminated, and an adhesive portion 22 without the coating layer 21 is provided.
