Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a delivery slip which can be thermally copied by thermal recording by a thermal printer. The thermal copy slip of the present invention is mainly used for applications in which data necessary for delivery of a package is copied and recorded and then attached to the package to be delivered.

[0002]

2. Description of the Related Art Generally, a slip used by a home delivery service or the like is a delivery slip of a pressure-sensitive copying system in which three or more sheets are one book, and necessary information is handwritten with a ballpoint pen or the like. ing. To cope with such a current situation, a form has been proposed in which the number of copy slips for delivery is reduced and information is recorded by a thermal copying method instead of a pressure-sensitive copying method (Japanese Patent Application No. Hei 10-26139).
1-371029). This method consists of two thermal transfer papers, upper and lower, and it is only necessary to write information such as the destination and sender directly from the computer, and the information required by the delivery company at the relay point etc. is the bar code information printed on the slip. Process by This thermal copying slip for delivery is very effective when a large number of articles are sent at once, that is, when a so-called large sender directly takes in information from a computer terminal.

[0003] When a delivery copy slip on which information is recorded by a computer is attached to a package to perform pickup and delivery, the sender usually does not need a copy slip because the home delivery information remains in the computer terminal. Must have at least three copies of a copy of the department that performs the delivery service, a copy of the delivery person for receiving a receipt upon completion of the delivery, and a copy of the copy for the consignee.
Seed copy slip must be affixed. Here, the copy for the consignee may be left on the package, but the copy for the department performing the home delivery service and the copy for the delivery person can be easily separated from the copy slip attached to the package. desired. When separating these slips, if the peeling strength of the glue layer that bonds them to each other is too weak, they will be peeled off during information recording or transportation by a thermal printer, and if the peeling strength is too strong, the slips will break during separation. There was a problem that would. For this reason, the glue layer must be applied to give a uniform and appropriate peel strength, but since the applied amount could not be visually judged, trial and error was required to determine the appropriate amount of the adhesive. Had been repeated. Further, a copy slip is usually provided with a release layer at a position facing the glue layer in order to adjust the peel strength and to easily separate each slip without breaking. However, since the width and thickness of the release layer also affect the peel strength, several tests have been required to determine the width and thickness of the release layer.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a thermo-copyable delivery slip which can be easily separated without damaging each slip which is a constituent element when necessary. An object of the present invention is to provide a delivery slip in which the width and thickness of a given release layer can be easily visually judged.

[0005]

The inventors of the present invention focused on the fact that by coloring the release layer, the width and thickness of the release layer giving an appropriate peel strength can be easily determined visually. Was completed. That is, the present invention has, on one surface, a heat-sensitive coloring layer that receives a thermal action corresponding to information and records the information, and a heat-sensitive member that has a heat transfer layer on the other surface.

(3) Tack Sheet The tack sheet 20 is provided on one surface of the base sheet (C) 21.
A chloroprene rubber-based, nitrile rubber-based, styrene-butadiene rubber-based or other arbitrary pressure-sensitive adhesive is applied to form a pressure-sensitive adhesive layer 23, which is further provided with a release paper 24. You. The base sheet (C) 21 used is the same as the base sheet (A) or (B) 11
Alternatively, it may be arbitrarily selected from those described for 31, but does not have an information entry column on the surface facing the image receiving member 30. That is, in the thermal copy slip 100 of the present invention, no information is recorded on the tack sheet 20 by the thermal action of the information mode transmitted through the thermal member 10 and the image receiving member 30.
The release paper 24 is used to avoid contamination of the pressure-sensitive adhesive layer 23 and adhesion to other articles during storage and transportation before use of the thermographic slip 100, and is conventionally used in this field. (For example, siliconized paper, waxed paper, etc.) can be used.

The thermal copy sheet for delivery of the present invention is constructed by adhering the above-mentioned heat-sensitive member (1) 10, image-receiving member (2) 30, and tack sheet (3) 20 to each other so that they can be separated when necessary. You. Adhesion of these elements is achieved by contact between the paste layer and the ink composition coated portion having releasability. The glue layer 50 is made of an adhesive or a glue usually used in the art (for example, vinyl acetate emulsion, ethylene vinyl acetate emulsion, acrylic resin emulsion, urethane resin emulsion, synthetic rubber latex, and these adhesives and polyethylene wax). , Etc.) is applied to the surface of the heat-sensitive member 10 having the thermal transfer layer 14 and the surface of the image receiving member 30 not having the color developer layer 32. here,
The glue layer 50 may be formed on the periphery of each application surface or a part thereof, and particularly includes the entire periphery of the application surface, or the periphery of at least one application surface of the section separated by the separation means or a part thereof. . Therefore, as shown in FIG. 1, the thermal copy slip 100 for delivery is placed across the thermal recording direction (ie, X
When die cutting or perforation is performed (in the -X direction), it may be formed on the periphery of each section of each member separated by die cutting or perforation or on a part thereof. For example, in FIG. 1, the heat-sensitive member 10 and the image receiving member
In the section on the right side of 30, a glue layer 50 is formed on the periphery of the surface having the thermal transfer layer 14 and on one side along the separation line by die cutting or perforation on the surface having no color developer layer 32.

An application section 60 made of an ink composition having a releasability, which is a feature of the present invention, is adhered to the surface of the base sheet 21 of the tack sheet 20 which is adhered to face the adhesive layer 50. It is formed in a shape compatible with the shape of the paste layer 50. The ink composition having releasability is basically composed of a release agent (for example, a silicone-based lubricant such as an acrylate ester group-containing polysiloxane or a mercapto group-containing polysiloxane) and a colorant (conventionally in the printing field). Including commonly used dyes and pigments). The release agent contributes to imparting releasability to the application portion of the ink composition, and the colorant is blended so that the application portion can be visually confirmed. In particular, the present invention can visually confirm the thickness and width of the applied portion of the ink composition for imparting releasability, and the uniformity thereof, by adding the coloring agent. This makes the adjustment of the peel strength easier than before.

The ink composition having releasability may further contain a thin film-forming binder, various additives, a solvent and the like. Specific examples of the ink composition having releasability preferably used in the present invention include 85 parts by weight of a reaction product of hexamethylene diisocyanate and hydroxypropyl acrylate (a thin film-forming binder), butanediol. Glycidyl ether acrylate (property modifier) 10 parts by weight, p-dimethylaminobenzaldehyde (sensitizer) 3 parts by weight, benzophenone (sensitizer) 3 parts by weight, acrylate ester group-containing polysiloxane (release agent) 12 parts by weight And 2 parts by weight of cyanine blue (colorant).

The content of the release agent in the ink composition must be an amount capable of providing a desired peel strength between the heat sensitive member 10 and the image receiving member 30 and the tack sheet 20. If the content of the release agent in the ink composition is too small, the peel strength when these members are peeled from the tack sheet increases, and the members may be damaged. Also, if the content of the release agent is too large, the peel strength becomes small, but on the contrary, the adhesive strength becomes insufficient, and the member 10 or 20 may peel off during transportation as a copy slip 100 or during thermal recording work. There is. Therefore, the content of the release agent in the ink composition is, for example, 2 to 20 with respect to the total weight of the ink composition.
% By weight, preferably 5 to 15% by weight.

In the present invention, the peel strength can be adjusted by the content of the release agent in the ink composition having releasability or the width or thickness of the ink composition application section 60.

The glue layer 50 formed on the surface of the heat-sensitive member 10 having the thermal transfer layer 14 is bonded to the surface of the image receiving member 30 having the color developer layer 32 so as to face. Here, the surface of the image receiving member 30 having the color developer layer 32 is coated with an ink composition having releasability.
Since it does not have 60, the peel strength must be adjusted to be lower than the portion of the tack sheet 20 facing the surface of the base sheet 21.

The heat-sensitive copying slip 100 of the present invention is more preferably provided with the heat-sensitive coloring layer 12 and the heat-sensitive coloring layer 12 of the heat-sensitive member 10 for the purpose of preventing unnecessary color contamination of the print recording portion that occurs during transportation and / or handling. On the thermal transfer layer 14,
It may have first and second overcoat protective layers 15 and 16 formed from UV curable inks. In particular, the second overcoat protective layer 16 is preferably formed on the entire surface of the thermal transfer layer 14 except for the portion where the glue layer 50 is formed, while the first overcoat protective layer 15 is more preferably formed on the thermosensitive coloring layer 12. Is formed so as to cover the entire surface of the heat-sensitive coloring layer 12 excluding the designated location of the receipt stamp in the information entry field 160 and the designated location for pasting the revenue stamp or the like (the portion indicated by the arrow in FIG. 4).

The UV-curable ink suitably used for forming the first and second overcoat protective layers 15 and 16 may be any of those conventionally used, but is dried and cured by light energy. An overcoat ink containing a UV-curable resin may be used, and examples thereof include those described in JP-A-11-123870. Specifically, a UV-curable resin; a photopolymerization initiator; Agent; and, if necessary, an extender or the like. These U

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail in the following examples with reference to the accompanying FIGS. Example 1 Manufacturing method of thermal copying slip for delivery A thermal copying slip for delivery of the present invention comprising a heat-sensitive member, an image receiving member and a tack sheet as shown in FIGS. 1 to 3 is prepared according to the following steps (i) to (v). Manufactured. Step (i): Preparation of heat- sensitive member In the heat-sensitive member 10, after forming the heat-sensitive coloring layer 12 on the surface of the base sheet (A) 11 having the information entry column 160, the heat transfer layer 14 is formed on the other surface. It can be obtained by: Thermal coloring layer
12 is a liquid A prepared by mixing a color former with a water-soluble binder and pulverizing and finely pulverizing in a ball mill or a sand grinder for 8 hours, and pulverizing a developer and a water-soluble binder in water. A composition for forming a heat-sensitive coloring layer, which can be prepared by mixing with a liquid B that has been prepared by finely pulverizing,
A coating amount of ^{2 to} 8 g / m ^{2 on} one surface of the base sheet (A) 11
And formed by drying.

A heat transfer material is mixed by mixing a heat-fusible substance (ie, wax) and fine powder of leuco dye as a color former, further adding a plasticizer, if necessary, heating and melting them to disperse them uniformly. A coating solution for a layer is prepared in advance. The melting point and viscosity of the thermal transfer layer forming coating solution are usually
It can be adjusted depending on the type of wax and the amount used. In this coating liquid, a desirable mixing ratio of the color former and the wax may be, for example, 3 to 15 parts by weight of the color former per 100 parts by weight of the wax, but the present invention is limited to this range. Not something. The prepared thermal transfer layer coating solution was applied onto the other surface of the base sheet (A) 111 by flexographic printing or a flexographic coating machine to apply a coating amount of 2%.
By applying at a rate of 10 g / m ² to 10 g, the thermal transfer layer 14 is formed. Here, the coating amount and surface condition of the thermal transfer layer 14 are determined by the mesh of the gravure or flexographic printing plate.
Inches, most preferably 120-200 lines / inch and a depth of 10-60 μm, preferably a depth of 30-50 μm
It is preferable to apply using a flexographic or gravure printing plate having a mesh of.

More preferably, the previously prepared heat-sensitive member
On the 10 thermosensitive coloring layers 12 and the thermal transfer layer formed here
The first and second overcoat protective layers 15 and 16 are formed by applying a UV-curable overcoat ink on the respective layers. In the production process, the UV curable overcoat ink is designed so that the entire system is not heated to a high temperature due to a partial large shear stress applied during the kneading of the above components. However, it can be manufactured in the same manner as printing inks commonly used in the art. Each of the inks is kneaded using a three-roll mill, a sand mill, a KD mill, a ball mill, or the like, and dispersed to form an ink.

The first overcoat protective layer 15 is applied on the thermal transfer layer 14 at a coating amount of 0.1 to 2.5 g / m ² according to a lithographic, letterpress, screen, gravure, flexographic printing method. And may be formed by irradiating and curing ultraviolet rays. If the coating amount of the UV-curable overcoat ink is less than 0.1 g / m ² , unnecessary color contamination of the print recording portion during storage or transport cannot be sufficiently prevented, or 2.5 g / m ² . If it exceeds, the copying by the applied energy of the printer becomes insufficient.

Step (ii): Preparation of Image Receiving Member The image receiving member 30 is obtained by forming a color developer layer 32 on one surface of a base sheet (B) 31. The developer layer 32 is formed, for example, by applying a coating solution obtained by finely dispersing a developer in an aqueous solution of the latex and / or water-soluble binder using a ball mill, a sand grinder, or the like, to a base sheet (B).
31 can be formed by applying a dry coating weight in the range of 2.0 to 7.0 g / m ^{2 on} one side and drying.

Step (iii) Preparation of Tack Sheet A pressure-sensitive adhesive layer 23 containing a color developer and a latex or a binder is formed on one surface of the base sheet (C) 21 by a flexographic printing method or the like. A tack sheet 20 is prepared by forming a sheet at 3 to 20 g / m ² and further covering the sheet with a release paper 24. After preparing Tack Sheet 20, release paper
24 may be die cut or perforated so that it can be separated along its entire width or length. Most preferably, the release paper 24 of the tack sheet 20 is die-cut over the entire length in the thermal printing direction (that is, the YY direction in FIG. 1).

The ink composition application section 60 and / or the glue layer 50 facing the application section have release properties from the ink composition application section.
It is formed on the periphery of the image receiving member 30 and the tack sheet 20 or a part thereof. When the heat-sensitive member, the image-receiving member and the tack sheet are arranged to face each other, the adhesive is applied to the opposing peripheral portions of the surface of the heat-sensitive member having the thermal transfer layer and the surface of the image-receiving member not having the color developer layer or a part thereof. An adhesive is applied to form a paste layer. As the paste, those conventionally known in the art (for example, emulsion types such as vinyl acetate, chloroprene rubber, and acrylic rubber) can be used, and the paste is applied by a normal application method such as flexographic printing or silk screen printing. At the corresponding peripheral portion of the surface of the base sheet of the tack sheet adhered to the glue layer or a part thereof,
The ink composition having the releasability of the composition described above is applied by a normal application method such as offset printing or letterpress printing to form an ink composition application portion.
