DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tag base material for obtaining a cleaning tag which can be attached to an object to be washed by a lamination method via an adhesive layer and can be used for both dry cleaning and laundry cleaning.

[0002]

2. Description of the Related Art Conventionally, a cleaning is performed by printing a bar code or the like by an electrostatic photographic method on a tag substrate in which a sheet made of paper or plastic is provided with an adhesive layer having water resistance, solvent resistance and chemical resistance. Tag has been known (Japanese Unexamined Patent Publication No.
7399, JP-A-4-9200). This makes it possible to attach the tag to the object to be washed by attaching it in a ring shape via an adhesive layer, and it is easy to cause damage to the object to be washed and injury such as tenosynovitis of the attaching worker, and the efficiency of the attaching and detaching work is poor. This eliminates the need for staple mounting.

[0003] However, the above-described mounting method using an adhesive layer has a problem that it is difficult to form a cleaning tag that can be used for both dry cleaning and laundry cleaning.

That is, JP-A-3-247399 mentioned above discloses a pressure-sensitive adhesive using a base polymer containing an acrylic alkyl ester having a methyl group, an ethyl group or a butyl group as a component. We propose to form a water-, solvent-, chemical-, oil-, and heat-resistant adhesive layer with an adhesive using a fixed amount of a carboxyl-containing base polymer. At times, or during laundry cleaning, the state of lamination via the adhesive layer is released, and the tag often falls off the object to be washed, which is not practical.

[0005]

According to the present invention, the object to be washed is often subjected to both dry-type and laundry-type cleaning to carry out the washing process, and different types of tags for dry and laundry are prepared. Development of tag base material that can be used for both dry cleaning and laundry cleaning and that can be used to obtain a lamination-attached cleaning tag with an adhesive layer in consideration of the fact that using different types of devices can easily cause problems. As an issue.

[0006]

According to the present invention, a solvent-resistant adhesive layer A that withstands dry cleaning and a water-resistant adhesive layer B that withstands another type of laundry cleaning detergent aqueous solution are provided on one side of a sheet. While having a state in contact with the surface, each of the adhesive layers consisting of the adhesive layer A or the adhesive layer B is arranged so as not to overlap and adhere when the ends of the sheet are warped and folded together , and Sheet

[0007]

By providing the adhesive layer A and the adhesive layer B having the above-described structure, attaching a tag base material to the adhesive layer A and attaching the tag base material to an object to be washed, the method is applied to both dry and laundry cleaning methods. Obtain a cleaning tag of a lamination attachment type via an adhesive layer, which is free of a laminating state even after processing and does not fall off from the object to be washed, and thus can be used for both dry cleaning and laundry cleaning. be able to.

[0008]

EXAMPLE The tag base material of the present invention comprises, on one side thereof, a solvent-resistant pressure-sensitive adhesive layer A resistant to dry cleaning and a water-resistant pressure-sensitive adhesive layer B resistant to another type of laundry cleaning detergent aqueous solution. While having in contact with the surface on one side, each of the adhesive layers consisting of the adhesive layer A or the adhesive layer B is arranged so as not to overlap and adhere when the ends of the sheet are warped and joined together , and Said Sea

FIG. 1 shows an example of the tag substrate of the present invention. 1 is a sheet, 2 is an adhesive layer A, and 3 is an adhesive layer B. Reference numeral 4 denotes a separator, and 5 denotes a fold line such as a perforation provided as needed, which aims at improving the bendability of the tag base material.

As a sheet , a thermal transfer recording method is used on one side.

I can . The sheet thickness is 5 to 50 in terms of strength and flexibility.
The thickness is generally 0 μm, especially 20 to 250 μm, but may be appropriately determined according to the purpose of use.

[0011] showed example the paper-based sheet in FIG. 1
1 is a paper base, 12 is an ink receiving layer , and 13 and 14 are
It is a plastic coating layer . According to such a paper-based sheet,
The information can be printed clearly and sharply by the thermal transfer recording method via a thermal transfer printer, etc. , and the preservability of the applied print is excellent, and the applied print does not disappear even if it is used for cleaning while exposing the printing surface. Thus, it is possible to obtain a tag base material which does not need to cover the printed surface with a protective cover. Examples of the paper base include paper-washing resistant paper made of high-quality paper or the like having a basis weight of 80 to 200 g, particularly 100 to 150 g, and laminated paper or coated paper of a plastic film.

In the above, if the rigidity is insufficient, such as a paper-washing paper having a basis weight of less than 80 g, for example, when a cleaning tag is used, it is bent smoothly when passing through a button hole or a belt stopper of clothing. Insufficient handleability and workability, such as the inability to perform, and the problem of tag tearing during washing due to insufficient strength is likely to occur. On the other hand, if the rigidity is too strong, such as a paper-washing paper having a basis weight of more than 200 g, when the end is adhered in a ring shape (loop shape) via an adhesive layer, it is peeled off by a repulsive force and adhered to a washing object or the like. Inconveniences such as falling off are more likely to occur.

The ink receiving layer can be formed by applying a polymer which can be printed by a thermal transfer recording method by an appropriate method such as a coating method, a dipping method and a screen method. As the polymer,
For example, polyurethane or polyamide, particularly aromatic polyamide, polyethylene terephthalate, and the like, which have good compatibility with the ink ribbon or the ink in the thermal transfer recording system, are preferably used, and those having excellent heat resistance are particularly preferred.

The thickness of the ink receiving layer is 0.1 to 10 μm
However, from the viewpoints of printability and image storability, it preferably has a center line surface roughness of, for example, about 1.7 to 3.0 μm. In such a case, even if a protective cover is not provided on the pattern formed by thermal transfer, the pattern can withstand cleaning and does not disappear.

The plastic sheet or the ink receiving layer may be colored for the purpose of improving the contrast of the applied pattern, improving the visibility of the tag, and the like. The color is arbitrary, but a light color system is preferable for barcode printing from the viewpoint of legibility. The coloring method is arbitrary, such as, for example, a method of adding a coloring agent composed of an organic or inorganic pigment or dye, or a coating method.

Examples of the white colorant include ceramic powders such as titania, silicon carbide, silicon nitride, boron nitride, alumina, zirconia, silicon oxide, barium titanate, calcium carbonate, titanium oxide, talc, CoO-Al ₂ O ₃ , NiO ₂ -CrO ₃ , MnO ₂ -Cr ₂ O
