Description

  The present invention relates to an information recording adhesive sheet that can be used as a delivery slip or a shipping slip.

As an information recording adhesive sheet currently used as a delivery slip, a shipping slip, etc., for example, as shown in FIGS. 1 to 6, an information recording base paper 101 can be separated into a plurality of pieces 101a, 101b. A so-called one-part type has been widely used (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3). The plurality of pieces 101a, 101b,... Can be separated by separating means S, S,..., Such as slits and perforations, and each includes, for example, a sticker slip 101a, a delivery slip 101b, a store slip 101c, a delivery statement ( It is used as a payment slip (not shown) or the like. Specifically, for example, the sticker slip 101a, the delivery slip 101b, and the like are pasted on an adherend such as a cardboard case, and the delivery slip 101b and the like are received at the delivery destination and taken home. As a configuration for enabling this pasting and taking home, there are the following forms.
That is, (1) information is provided on one of a plurality of adhesive layers 102 and 102 on a tack paper 106 composed of an adhesive base paper 103, an adhesive layer 104, and a release paper 105 as shown in FIGS. Form in which recording base paper 101 is laminated, (2) Information recording base paper 101, adhesive layer 104 and release paper 105 are laminated in this order as shown in FIGS. A mode in which a paste-killing layer 108 made of a resin or the like is interposed between the adhesive layer 104 and the release paper 105 at the site serving as the store holder 101c. (3) For information recording as shown in FIGS. A pressure-sensitive adhesive layer 104 is provided on the back side of the base paper 101, and this pressure-sensitive adhesive layer 104 is covered with a release paper 105. The pressure-sensitive adhesive layer 104 is provided with a portion serving as a sticker slip 101a and a delivery slip 101b. The part between the storekeeper 101c and the hook It is a form which is only both sides of the portion to be a delivery form 101b. These forms can be pasted and taken home as described above.
However, the form (1) (three-layer type) has the adhesive base paper 103, and therefore, waste of resources occurs and the cost increases. Further, since the sheet becomes thick, when cut paper is used, the number of sheets to be fed is reduced and the printer is not runnable. When continuous paper is used, the running load on the printer is increased due to an increase in mass. In the form (2) (paste-killing type) and the form (3) (bridge type), a part of the plurality of pieces 101a, 101b..., For example, the delivery slip 101b is separated from the release paper 105. Therefore, there is a possibility that air enters between them, which may cause printing defects and paper jams in the printing process. In particular, in recent years, the printing method for the information recording base paper 101 has been changed from the impact printing method to the laser printing method, and there is a demand for high-speed printing processing. Increasing importance. In the form (2) (adhesive-killing type), the problem is that the information recording base paper 101 cannot be freely selected, and the adhesive layer is exposed on the surface when the adhesive-killing layer is damaged. There was also a problem of expression.

  The main problems to be solved by the present invention are the pressure-sensitive adhesive sheet for information recording that does not cause problems such as waste of resources, high cost, sheet thickness and the like, and does not cause problems such as printing failure, paper jam, and peeling in the printing process. Is to provide.

The present invention that has solved this problem is as follows.
[Invention of Claim 1]
An information recording base paper separable into a plurality of pieces, an adhesive layer provided on the back side of the base paper, and a release sheet provided with a first release layer on the surface covering the adhesive layer, An information recording pressure-sensitive adhesive sheet comprising:
At least a part of the back side of the base paper is provided with a second release layer in place of the pressure-sensitive adhesive layer and an adhesive layer that is pseudo-adhered to the second release layer after curing in this order, and the release sheet The information recording pressure-sensitive adhesive sheet is characterized in that the first release layer is not provided in a portion facing the second release layer .

  According to the present invention, it is an information recording pressure-sensitive adhesive sheet that does not cause problems such as waste of resources, high cost, and sheet thickness, and does not cause problems such as defective printing, paper jamming, and peeling in the printing process.

Next, an embodiment of the present invention will be described.
The information recording adhesive sheet of this embodiment is shown in FIGS. The information recording adhesive sheet of this embodiment includes an information recording base paper 1 that can be separated into a plurality of pieces 1a, 1b, ..., an adhesive layer 4 and a first release layer 5a provided on the back side of the base paper 1. The basic structure is a pseudo-adhesive layer 9 that is pseudo-adhered after curing, and a release sheet 5 having a first release layer 5a provided on the surface covering the pressure-sensitive adhesive layer 4 and the pseudo-adhesive layer 9.

  The number, size, shape, etc. of the plurality of pieces 1a, 1b,... Constituting the information recording base paper 1 are not particularly limited. In this embodiment, the left and right adjacent sticker slips 1a, delivery slips 1b, store openings 1c, and shipping slips and shipping matters 1d existing over the entire lower side of these, that is, composed of four pieces, It is separable. The plurality of pieces 1a, 1b,... Can be separated by separating means S, S,.

  On the other hand, the material and thickness of the information recording base paper 1 are not particularly limited. Examples of the material of the information recording base paper 1 include craft paper, high quality paper, glassine paper, parchment paper, rayon paper, coated paper, synthetic paper, and paper laminated with a resin film. Furthermore, the durability when wet with rain is increased by subjecting these materials to water resistance treatment. Various recycled paper may be used from the viewpoint of environmental protection. However, in this embodiment, from the viewpoint of resource reuse, a resin film is not used as the pseudo-adhesive separation layer 9 as described later. Therefore, it is preferable to avoid paper or the like on which a resin film is laminated so as not to inhale this purpose. The thickness of the information recording base paper 1 is usually 50 to 300 μm.

  There is no particular limitation as to what component the adhesive layer 1 provided on the back side of the information recording base paper 1 is formed of. Examples of the constituent components include known organic solvent-based adhesives, acrylic emulsion-based adhesives, natural rubber-based adhesives, synthetic rubber-based adhesives, silicone-based adhesives, hot-melt-based adhesives, UV-curable adhesives, and the like. The pressure-sensitive adhesive can be exemplified.

  Although the thickness of the adhesive layer 4 is not specifically limited, Usually, 5-50 micrometers, Preferably it is 10-30 micrometers.

  The pressure-sensitive adhesive layer 4 is a portion that does not need to be attached to the adherend, in this embodiment, the store receipt 1c, the shipping details, the contact details 1d, etc., and the portion that is peeled off from the adherend, in this embodiment, the delivery slip Provided in a portion excluding the portion 1b. That is, in this embodiment, it is provided in the portion that becomes the sticker slip 1a and the portion between the delivery slip 1b and the store opening 1c.

  On the other hand, the pseudo-adhesive layer 9 is provided in a portion where the pressure-sensitive adhesive layer 4 is not provided, that is, in the present embodiment, in the portions of the delivery slip 1b and the store opening 1c. That is, the pseudo adhesive layer 9 is provided in place of the pressure-sensitive adhesive layer 4 on at least a part of the back surface of the information recording base paper 1. This pseudo-adhesive layer 9 is pseudo-adhered to the release sheet. However, since the adhesiveness is lost when the pseudo-adhesive layer 9 is peeled off from the release paper, the delivery slip 1b or the like attached to the adherend by connecting with the sticker 1a is attached. The separation means S such as slits and perforations can be separated from the adherend. For example, a receipt stamp can be received and taken home. Further, since the delivery slip 1b or the like is not separated from the release paper before the release sheet is peeled off, a problem such as paper jam in the printing process does not occur. Further, in this embodiment, unlike the conventional embodiment (1) described above, it is not necessary to provide (intervene) the adhesive base paper 103, so that problems such as waste of resources and high costs do not occur.

Here, the information recording adhesive sheet of the present embodiment is a single sheet as shown in FIG. 8 in at least a part of the back surface of the base paper 1, in the present embodiment, in the delivery slip 1 b and the store opening 1 c portion. The pseudo-adhesive layer 9 is configured by providing a second release layer 9a in place of the pseudo-adhesive layer 9 and an adhesive layer 9b that is pseudo-adhered to the second release layer 9a in this order after being cured. in the portion facing the second separation layer of the sheet 5, it shall be the form in which the first separation layer 5a is not provided. This form is only different from the previous form (the adhesive layer (pseudo-adhesive layer 9) remains adhered to the base paper 1) in that the adhesive layer is peeled off by being adhered to the release sheet 5, The same effect as the previous embodiment can be obtained.

  Here, the pseudo adhesive layer 9 of the present embodiment is formed by applying an adhesive. By avoiding the formation of a sheet such as a resin film, it becomes easy to reuse resources. In addition, various known coating methods such as roll coater, blade coater, comma coater, curtain coater, etc. can be used for the adhesive and adhesive, and printing methods such as letterpress printing, gravure printing, screen printing and offset printing can be used. It may be used, and it is desirable that the coating film be formed uniformly. If the coating film is uniform, the adhesiveness of the pressure-sensitive adhesive to the adherend is improved, the surface irregularities of the information recording base paper 1 are reduced, and the information recording suitability is excellent. In particular, according to the coating method using a printing method, there is an advantage that the part where the pseudo adhesive layer 9 is formed can be easily and quickly changed. Furthermore, if a facility for applying the adhesive and the adhesive in one pass is used, a high-quality information recording pressure-sensitive adhesive sheet can be produced only by increasing the adhesive cost.

  Adhesives include general hot melt adhesives, two-component reactive adhesives, organic solvent adhesives, water-based emulsion adhesives, UV curable adhesives, and UV curable adhesives. Appropriately from pressure-sensitive adhesives that can be peeled off later, heat-sensitive adhesives that adhere when given heat is applied but can be peeled off even after adhesion, and rehumidifying adhesives that adhere when moisture is applied but can be peeled off after adhesion You can select and use. These adhesives can be appropriately selected according to needs, such as those that do not have tackiness after curing, or those that have adhesive strength that can be peeled off again on the adherend.

  Antioxidants, heat stabilizers, ultraviolet absorbers, slip agents, antistatic agents, antifogging agents, colorants, fillers, and the like may be added to these adhesives.

  Here, the pressure-sensitive adhesive layer 4 is preferably formed from a rubber-based pressure-sensitive adhesive. In this regard, when the information recording adhesive sheet is, for example, a shipping slip, if the adherend is uneven, the adhesive does not completely adhere to the adherend and there is a risk of peeling. However, since the rubber adhesive has a large molecular weight and elasticity, there is an effect that the pressure-sensitive adhesive easily adheres to the adherend. It is also a preferable form that the rubber-based adhesive is mixed with an anti-aging agent or the like.

  Of course, when there are few irregularities on the adherend or when there is no problem even if pseudo adhesive remains on the back of the slip, water-based emulsion type adhesives such as organic solvents and acrylic resins, hot melt adhesives, ultraviolet rays It is also a preferred form to use a known adhesive such as a curable adhesive.

  Although the thickness of the layer formed with an adhesive agent and an adhesive is not specifically limited, Usually, 2-50 micrometers, Preferably it is 4-25 micrometers. When the coating is uniformly performed in this way, the pseudo adhesive layer 9 and the pressure-sensitive adhesive layer 4 become thin. Therefore, in the printing process, the number of sheets to be fed increases when cut sheets are used, and the load on the printer decreases due to a decrease in mass when continuous sheets are used.

  On the other hand, the material and thickness of the release paper 5 are not particularly limited. The release paper 5 is made of, for example, paper, woven fabric, plastic film or the like, and the upper surface (surface), that is, the surface on the pressure-sensitive adhesive layer 4 side, is subjected to a release treatment with a silicone release agent or the like. What is being done can be illustrated. Moreover, the thickness of the release paper 5 is usually 30 to 150 μm.

  In this respect, the pseudo-adhesive force can be partially weakened by performing paste-free printing with halftone dots on the surface of the release paper 5, making it easy to peel off the end portion of the delivery slip 1 b and the personal information entry portion of the sticker slip. Can do so. In particular, a perforation can be provided in the personal information entry part to facilitate cutting. The personal information entry unit may be pseudo-adhered to the release paper with an adhesive.

  In addition, the first and second release layers are not particularly limited as long as they exhibit releasability. For example, silicone, long-chain alkyl polymer, polyolefin, alkyd resin, fluorine compound and the like can be formed as components. .
