Description

  The present invention relates to a label that can be partially peeled after being attached to an adherend such as a delivery label attached to a delivery item.

  FIGS. 3A and 3B are diagrams showing a configuration example of a conventional delivery label, where FIG. 3A is a diagram showing a laminated structure, FIG. 3B is a diagram showing a receiving piece 510 shown in FIG. It is a figure which shows the tag 520 shown to a).

  In this conventional example, as shown in FIG. 3 (a), a receiving piece 510 in which a back carbon printing layer 550 is laminated on one surface, and a release label 540 having a release paper 540 bonded thereto via an adhesive layer 530a. 520 is bonded to the surface of the receiving piece 510 on which the back carbon printing layer 550 is laminated and a part of the surface of the tag 520 where the adhesive layer 530a is not laminated, by the adhesive layer 530b.

  Further, as shown in FIG. 3B, the receiving piece 510 has a delivery information entry area for filling in information such as the delivery destination and delivery source of the delivery to which the delivery label is attached, and the name of the delivery item. 511, and a stamp area 512 for pressing a receipt stamp when a recipient of a delivery to which the delivery label is attached receives the delivery.

  In addition, as shown in FIG. 3C, the delivery information entered in the delivery information entry area 511 of the receiving piece 510 is copied to the tag 520 by the back carbon printing layer 550 laminated on the receiving piece 510. An information entry area 521 is provided.

  In the delivery label configured as described above, before and after being affixed to the delivery item, information such as the delivery destination and delivery source of the attached delivery item and the item name of the delivery item is entered in the delivery information of the receiving piece 510. When the area 511 is entered, in this state, the receiving piece 510 is adhered on the tag 520 by the adhesive layer 530b, and the back carbon printed layer 550 is formed on the surface of the receiving piece 510 facing the tag 520. Therefore, the information entered in the delivery information entry area 511 of the receiving piece 510 is copied to the delivery information entry area 521 of the tag 520 by the back carbon print layer 550.

  After that, when the delivery with the delivery label attached is received at the delivery destination, the receipt stamp is stamped on the stamp area 512 provided on the receipt strip 510 and the receipt strip 510 is peeled from the tag 520. . The receiving piece 510 peeled off from the tag 520 is brought back by the delivery company, and it is managed that the delivery item has been delivered to the delivery destination. The receiving piece 510 is bonded to the tag 520 by the adhesive layer 530b. However, since the bonding area is small, the receiving piece 510 can be easily peeled off from the tag 520.

  When the receiving piece 510 is peeled off from the tag 520, the tag 520 appears. However, as described above, the delivery information entry area 521 of the receipt piece 510 is filled in the delivery information entry area 511 of the receipt piece 510. The delivered delivery information is copied.

  As described above, in the delivery label attached to the delivery item, when the delivery item is delivered to the delivery destination, the delivery information is given to the delivery item, and the sheet on which the delivery information is filled is delivered to the delivery company. Needs to be configured so that it can be taken home.

In addition, as described above, when the delivery item is delivered to the delivery destination, the delivery information is given to the delivery item, and the delivery company can take back the sheet on which the delivery information is entered. In the delivery slip, the delivery information is entered, the receiving sheet is peelably bonded to the adhesive sheet that is attached to the delivery, and a self-coloring agent layer is provided in the area where the delivery information of the adhesive sheet is entered. In addition, when the delivery information is entered on the receiving sheet, the self-coloring agent layer is colored by the pressure, and thereby a delivery slip configured so that the delivery information is entered on the attached sheet is considered ( For example, see Patent Document 1.) In this delivery slip, the receiving sheet is adhered to the adhesive sheet that is adhered to the delivery by the adhesive, and the adhesive sheet is peeled off, and the self-coloring agent layer is provided on the adhesive sheet. When the delivery information is entered on the receiving sheet with the adhesive sheet and the receiving sheet adhered, the delivery information is also entered on the adhesive sheet, and then the release sheet is peeled off from the adhesive sheet. The sheet will remain attached to the delivery.

  However, in the case of peeling from the adherend as in the delivery slip described above, in order to give the information to the adherend while the part where the information is written is peeled off, It is necessary to have a configuration in which a sheet that gives information to an adherend such as a receiving sheet and a sheet that is peeled from the adherend such as a receiving sheet are bonded via an adhesive, There is a problem that the cost increases accordingly.

  The present invention has been made in view of the problems of the conventional techniques as described above, and is a portion in which information is described when peeling from an adherend without causing an increase in cost. It aims at providing the label which can give the information to a to-be-adhered body, while peeling.

In order to achieve the above object, the present invention provides:
A base substrate provided with an information entry area on one side;
A release layer that is laminated on the surface of the base substrate where the information entry area is not provided and is cohesively destroyed when a release force is applied to the base substrate;
A pressure-sensitive color-developing layer that is laminated on at least the area facing the information entry area of the surface of the release layer where the base substrate is not laminated, and develops color when pressure is applied;
And a pressure-sensitive adhesive layer laminated to cover the pressure-sensitive color developing layer on the surface of the release layer on which the pressure-sensitive color developing layer is laminated.

Also, a base substrate provided with an information entry area on one side,
Layered on the surface of the base substrate where the information entry area is not provided, and a peeling layer that peels off when a peeling force is applied to the base substrate;
A pressure-sensitive color-developing layer that is laminated on at least the area facing the information entry area of the surface of the release layer where the base substrate is not laminated, and develops color when pressure is applied;
A pressure-sensitive adhesive layer laminated to cover the pressure-sensitive color developing layer on the surface of the release layer on which the pressure-sensitive color developing layer is laminated,
The peel adhesive strength of the release layer is weaker than the peel adhesive strength of the pressure-sensitive adhesive layer.

  The pressure-sensitive color developing layer is characterized by comprising a dye-encapsulating microcapsule and a developer.

The pressure-sensitive adhesive layer is characterized by being colored in a color different from the color developed in the pressure-sensitive color developing layer.
The release layer is provided with an information entry area for copying information entered in the information entry area by mirror image printing.

  In the present invention configured as described above, when the information is entered in the information entry area provided on one surface of the base substrate after being adhered to the adherend by the pressure-sensitive adhesive layer, The pressure is transmitted to the pressure sensitive color developing layer laminated on the release layer, whereby the information entered in the information entry area of the base substrate appears in the pressure sensitive color developing layer. Thereafter, when the label is peeled off from the adherend, the release layer is agglomerated and broken, thereby peeling off the adherend. At this time, the pressure-sensitive color developing layer laminated on the release layer remains on the adherend together with the pressure-sensitive adhesive layer. For this reason, the base substrate in which information is entered in the information entry area is peeled off from the adherend, and the information appearing in the pressure-sensitive color developing layer is applied to the adherend.

  Moreover, after being attached to the adherend by the pressure-sensitive adhesive layer, when information is entered in the information entry area provided on one side of the base substrate, the pressure due to the entry is pressure-sensitive laminated on the release layer. Information transmitted to the information entry area of the base substrate appears in the pressure-sensitive color development layer. After that, when this label is peeled off from the adherend, the peel layer peels off because the peel adhesive strength of the peel layer is weaker than the peel adhesive force of the pressure-sensitive adhesive layer. It will be peeled off. At this time, the pressure-sensitive color developing layer laminated on the release layer remains on the adherend together with the pressure-sensitive adhesive layer. For this reason, the base substrate in which information is entered in the information entry area is peeled off from the adherend, and the information appearing in the pressure-sensitive color developing layer is applied to the adherend.

  As described above, in the present invention, when information is entered in the information entry area provided on one surface of the base substrate after being adhered to the adherend by the adhesive layer, the information is peeled off. Appears in the pressure-sensitive color developing layer laminated to the layer, and then peels off the label from the adherend, the release layer cohesively breaks down, and the pressure-sensitive color developing layer laminated on the release layer becomes the adhesive Since it was set as the structure which peels from a to-be-adhered body in the state which remained in the to-be-adhered body with the layer, the base material which provides information to a to-be-adhered body, and the base material which is peeled from a to-be-adhered body are Without being configured to be bonded via an adhesive, when the information is peeled off from the adherend, the entered information is attached while the part where the information is written is peeled off from the adherend. Can be given to the body.

  In addition, when the information is entered in the information entry area provided on one surface of the base substrate after being adhered to the adherend by the adhesive layer, the information is pressure-sensitive color development laminated on the release layer. Then, when this label is peeled off from the adherend, the peelable layer peels off, and the pressure-sensitive coloring layer laminated on the peelable layer remains on the adherend together with the adhesive layer. The same effect as described above can be obtained even in a configuration in which the substrate is peeled from the adherend in a state.

  Embodiments of the present invention will be described below with reference to the drawings.

  1A and 1B are diagrams showing a delivery label as an embodiment of the label of the present invention. FIG. 1A is a view showing a laminated structure, and FIG. 1B is a view of the resin sheet 10 shown in FIG. (C) is the figure which looked at the peeling destruction layer 20 shown to (a) from the back surface.

  In this embodiment, as shown in FIG. 1A, color is generated by applying pressure to a resin sheet 10 that is a base substrate and a part of the surface that is laminated to the resin sheet 10 and is not laminated. Adhesion laminated so as to cover the pressure-sensitive color developing layer 50 over the entire surface of the peel-breaking layer 20 on which the pressure-sensitive color developing layer 50 is laminated. It is comprised from the agent layer 30 and the release paper 40 adhere | attached on the peeling destruction layer 20 through the adhesive layer 30 so that peeling was possible. In addition, the peeling destruction layer 20 is a thing to be agglomerated and destroyed when a peeling force is applied. Therefore, the peeling adhesive force of the pressure-sensitive adhesive layer 30, the breaking strength of the resin sheet 10, and the peeling adhesive force of the peeling breaking layer 20 Are compared, the breaking strength of the resin sheet 10 is the strongest, and the peeling adhesive strength of the peeling breaking layer 20 is the weakest. The peel adhesive strength of the peel break layer 20 is 5 to 150 g / cm width, and the peel adhesive force of the pressure-sensitive adhesive layer 30 is preferably 100 to 1500 g / cm.

  Further, as shown in FIG. 1B, on the surface of the resin sheet 10, a delivery for entering information such as a delivery destination and a delivery source of the delivery item to which the delivery label 1 is attached, a product name of the delivery item, and the like. An information entry area 11 and a stamp area 12 for pressing a receipt stamp when a recipient of a delivery to which the delivery label 1 is attached receive the delivery are provided. The resin sheet 10 has a thickness of 10 to 500 μm, preferably 20 to 300 μm. For example, the resin sheet 10 is an ethylene resin such as high density polyethylene, medium density polyethylene, or low density polyethylene, or a propylene resin or polymethyl. -1-pentene, polyolefin resins such as ethylene-cyclic olefin copolymer, polyamide resins such as nylon-6, nylon-6,6, nylon-6,10, nylon-6,12, polyethylene terephthalate It consists of polymers, thermoplastic polyester resins such as polyethylene naphthalate and aliphatic polyester, and thermoplastic resins such as polycarbonate, atactic polystyrene, syndiotactic polystyrene, and polyphenylene sulfide. These may be used as a mixture of two or more. Can The Among these, it is preferable to use polyolefin resin. Furthermore, among polyolefin resins, propylene resins and high density polyethylene are more preferable from the viewpoints of cost, water resistance, and chemical resistance.

  Further, as shown in FIG. 1C, the delivery information entered in the delivery information entry area 11 is copied on the back surface of the delamination layer 20 in the area facing the delivery information entry area 11 of the resin sheet 10. A delivery information entry area 21 is provided by mirror image printing, and a pressure-sensitive coloring layer 50 is laminated in the delivery information entry area 21.

  Below, the usage method of the delivery label 1 comprised as mentioned above is demonstrated.

  FIG. 2 is a diagram for explaining a method of using the delivery label 1 shown in FIG.

  First, the release paper 40 is peeled from the delivery label 1 shown in FIG. 1, and this delivery label 1 is stuck to the delivery 60 which is an adherend (FIG. 2 (a)).

  In this state, when the delivery information 13 indicating the delivery destination, delivery source, product name, etc. of the delivery 60 is entered in the delivery information entry area 11 provided in the resin sheet 10 (FIG. 2B), the pressure caused by the entry Is transmitted to the pressure-sensitive color developing layer 50 laminated on the back surface of the peeling fracture layer 20, whereby information entered in the delivery information entry area 11 of the resin sheet 10 appears in the pressure-sensitive color developing layer 50.

  Here, the pressure-sensitive coloring layer 50 will be described in detail.

  The pressure-sensitive color developing layer 50 may be composed of, for example, a mixture of a developer and a dye-encapsulated microcapsule composed of microcapsules having an average particle size of 5 μm or less. In that case, the particle size of the microcapsule constituting the dye-encapsulated microcapsule is adjusted to an average particle size of 5 μm or less in the state of primary particles or secondary particles in which several particles are aggregated. As the microcapsule ink, preferably prepared is a microcapsule-containing oil-based coating solution disclosed in JP-A-7-216273 or JP-A-8-39928 and a production method thereof. Is good.

  For example, a leuco dye is used as the core material, and a urea-formalin resin is formed by an in situ method using a styrene-maleic anhydride partial hydrolyzate having an acid catalyst and an emulsifying function, and melamine or urea and formalin or a prepolymer thereof. For the dye-encapsulated microcapsule produced using this as a capsule wall material, a surfactant layer having an affinity for both the capsule wall material and the ink vehicle is provided so as to cover the capsule wall material, and further vacuum distillation is performed. By selectively vaporizing and removing water by the method, the dye-encapsulated microcapsules produced in the aqueous system can be replaced in the ink vehicle in a dispersed state through this surfactant layer.

  With dye-encapsulated microcapsule inks adjusted in this way, it is very unlikely that the individual dye-encapsulated microcapsules will adhere to each other, i.e., cause secondary agglomeration and enlarge the particle size. Similarly, the average particle size of 5 μm or less can be easily achieved. In addition, by using an ultraviolet curable ink vehicle that is generally used, an offset printing machine or the like can be used as a spot on an ordinary printing sheet such as high-quality paper, synthetic paper, or synthetic film. This ink layer can be applied.

  When a self-coloring ink is prepared by mixing with this, the developer is preferably an ink made of an electron-accepting resin or clay, such as an oil-soluble phenol formalin resin or an acidic developer. What was obtained by dissolving clay or an aromatic carboxylic acid derivative in a low-boiling organic solvent such as aromatic hydrocarbon, alcohol or ester together with a surfactant such as alkylbenzene sulfonate is preferred. In view of the self-coloring state, the mixing ratio with the above-described dye-encapsulated microcapsule ink is in the range of 2: 8 to 8: 2, preferably 4: 6 to 6: 4 by weight.

  The delivery 60 to which the delivery label 1 is attached is delivered to the delivery destination according to the delivery information 13 entered in the delivery information entry area 11 and is received by the recipient who is the delivery destination of the delivery 60. The receipt stamp is pressed in the stamp area 12 provided in

  Thereafter, when the delivery label 1 is peeled off from the delivery 60, the peel break layer 20 is cohesively broken and peels off through the peel break layer 20 (FIG. 2 (c)). The pressure-sensitive coloring layer 50 laminated in the area facing the entry area 11 remains in the delivery 60 side together with the adhesive layer 30 (FIG. 2D). At this time, the information mirror-printed on the peeling break layer 20 also remains on the delivery 60 side together with the adhesive layer 30.

  Here, the peeling fracture layer 20 will be described in detail.

  The peeling fracture layer 20 of this embodiment contains, for example, 10 to 80% by weight of inorganic fine powder or organic fine powder and 90 to 20% by weight of thermoplastic resin, and peels the delivery label 1 from the delivery 60. Then, it aggregates and breaks by itself and adheres to the resin sheet 10 side and the pressure-sensitive adhesive layer 30 side, respectively, and the delivery label 1 comes to peel through the peel break layer 20. As materials for these thermoplastic resins, inorganic fine powders and organic fine powders, for example, those described in JP-A No. 2002-113817 can be considered. Specifically, as the thermoplastic resin, high-density polyethylene is considered. , Ethylene resins such as medium density polyethylene and low density polyethylene, or propylene resins, polyolefin resins such as polymethyl-1-pentene, ethylene-cyclic olefin copolymer, nylon-6, nylon-6,6, nylon- Polyamide resins such as 6,10, nylon-6,12, polyethylene terephthalate and copolymers thereof, thermoplastic polyester resins such as polyethylene naphthalate, aliphatic polyester, polycarbonate, atactic polystyrene, syndiotactic polystyrene, polyphenylene Sulf In addition, as the inorganic fine powder, calcium carbonate having a particle size of usually 0.01 to 15 μm, preferably 0.01 to 8 μm, more preferably 0.03 to 4 μm, calcined Examples include clay, silica, diatomaceous earth, talc, titanium oxide, barium sulfate, and alumina. As the organic fine powder, when the thermoplastic resin film is a polyolefin resin film, polyethylene terephthalate, polybutylene Terephthalate, polycarbonate, nylon-6, nylon-6,6, homopolymer of cyclic olefin cyclic olefin, copolymer of cyclic olefin and ethylene, etc., melting point of 120 ° C to 300 ° C, or glass transition temperature of 120 ° C to The thing which has 280 degreeC is mentioned, These can also be used in mixture of 2 or more types. That. Among these, it is preferable to use polyolefin resin. Furthermore, among polyolefin resins, propylene resins and high density polyethylene are more preferable from the viewpoints of cost, water resistance, and chemical resistance. Moreover, the thickness of the peeling fracture layer 20 is in the range of 0.1 to 10 μm, preferably 0.2 to 5 μm. If the thickness is less than 0.1 μm, sufficient peelability cannot be obtained, and if it exceeds 10 μm, there is no problem in the peel strength, but the transparency of the peel-breaking layer 20 is reduced, and the resin from the delivery 60 that becomes the adherend is resin. When the sheet 10 is peeled off, the information recognizability is lowered, and the delivery information 13 appearing on the pressure-sensitive color developing layer 50 becomes difficult to see.

  In a state in which the peel break layer 20 is coherently broken and the delivery label 1 is peeled through the peel break layer 20, the pressure-sensitive coloring layer 50 and the information mirror-printed on the peel break layer 20 are delivered together with the adhesive layer 30. Since it remains on the object 60 side, a mirror image printed information is transferred to the delamination-breaking layer 20 in the area where the delivery label 1 of the delivery object 60 is adhered, thereby forming a delivery information entry area 21. In addition, in the delivery information entry area 21, the delivery information 13 appearing on the pressure-sensitive coloring layer 50 can be visually recognized (FIG. 2 (e)). At this time, a part of the peeling destruction layer 20 remains on the pressure-sensitive coloring layer 50, but the thickness is extremely thin, so that the delivery information 13 appearing on the pressure-sensitive coloring layer 50 can be visually recognized. Become. Further, since the fine powder constituting the cohesive fracture layer 20 is adhered on the pressure-sensitive adhesive layer 30, the area where the pressure-sensitive adhesive layer 30 of the delivery 60 remains is sticky by the pressure-sensitive adhesive layer 30. Absent.

  As a result, the resin sheet 10 on which the delivery information 13 is written is peeled off from the delivery 60, and the delivery information 13 appearing on the remaining pressure-sensitive coloring layer 50 is given to the delivery 60. .

  Depending on the color and material of the delivery 60 to which the delivery label 1 is attached, it appears on the pressure-sensitive color developing layer 50 remaining on the delivery 60 side together with the adhesive layer 30 when the delivery label 1 is peeled off. The delivery information 13 may be difficult to see. Therefore, by mixing and coloring the pigment layer in the pressure-sensitive adhesive layer 30, it is possible to make the delivery information 13 easier to see regardless of the color or material of the delivery 60. More preferably, the adhesive layer 30 is colored in a color different from the delivery information 13 appearing by the pressure-sensitive color developing layer 50, thereby making the contrast clear and easier to see. For example, if a white pigment is mixed in the pressure-sensitive adhesive layer 30 to make the color of the pressure-sensitive adhesive layer 30 white, the color of the delivery 60 can be whatever the material or material on the white pressure-sensitive adhesive layer 30. Thus, the delivery information 13 is displayed, and the delivery information 13 does not become difficult to see.

  It is also conceivable that only the corner portion of the delivery label 1 does not have the pressure-sensitive adhesive layer 30 laminated on the peeling break layer 20, thereby facilitating the release of the delivery label 1 from the delivery 60. Even in such a case, the delivery label 1 begins to peel from the lower part of the peeling break layer 20, but when the peeled portion reaches the area where the adhesive layer 30 is laminated, the peel break layer 20 coheses and breaks off. It will peel off through the layer 20.

  In this embodiment, the pressure-sensitive color developing layer 50 is laminated in a region facing the delivery information entry region 11 on the surface where the resin sheet 10 of the peel fracture layer 20 is not laminated. The pressure-sensitive coloring layer 50 may be laminated on the entire surface where the sheet 10 is not laminated.

  Further, in the present embodiment, the delivery label 1 attached to the delivery item 60 has been described as an example, but the present invention is applied to any label that is attached to an adherend such as an article or a sheet. be able to. In addition, the usage method is not limited to handwriting the delivery information 13 on the delivery label 1 as in the present embodiment, but printing information using an impact printer on the label attached to the sheet. Is also possible.
