(First Embodiment) FIG. 1 is a view showing a first embodiment of a laminated release label according to the present invention. The laminated release label 10 includes a substrate 11 and a release layer 12 composed of a first release layer 12-1 and a second release layer 12-2.
, A resin layer 13, and an adhesive layer 14 are laminated in this order, and a barrier layer 15 is provided at a portion A on the release layer 12 where peeling is to be started.

The base material 11 is disposed on the surface of the laminated release label 10 and displays necessary information by printing or printing. The base material 11 is made of high quality paper, thermal paper, copy paper, kraft paper, glassine paper, Paper such as parchment paper, rayon paper, coated paper, synthetic paper, and paper laminated with a resin film is preferably used, but cellophane, stretched polypropylene, polyethylene terephthalate, stretched polystyrene, resin films such as polyvinyl chloride, etc. Is also good. The thickness of the display substrate 11 is usually 20 to 200 μm
The degree is preferred.

The release layer 12 is formed below the display substrate 11.
A first release layer 12-1 and a second release layer
12-2, and peels the base material 11 from the resin layer 13.
It is a layer that can be separated. The release layer 12 is made of PVA-LA
System, acrylate system, silicone system, polyolefin
Resin, such as fluorine-based, offset printing, letterpress printing
Thickness is 0.1
It is formed to about 20 μm. Also, by printing

Can be used. Note that the release ink (bath described later)
Or the resin layer 13 is formed.
Resin material is colorless or colored and transparent or translucent.
Preferably. Here, the first release layer 12-1 is
0.1 g / m of release ink (first printing) ^TwoMore than 20g
/ M^TwoHereinafter, the second release layer 12-2 is formed of a release ink (after
Printing) is 0.05 g / m^TwoMore than 15g / m^TwoLess than
Below, and the release ink (first printing) is
It is desirable that the coating amount per unit area be larger than
No.

The second release layer 12-2 comprises the first release layer 12
It is set so that the releasability is weaker than -1 (it is hard to make it peel). Materials with high releasability repel and are difficult to apply, and there are restrictions on the coating method, and it is difficult to provide a resin layer. Therefore, when viewed from the resin layer, a material having low releasability has a wider suitability. However, as a matter of course, it is difficult to peel off, and a material having high peelability is demanded. That is, making these two points compatible is the reason why the release layer is formed into multiple layers.
For this reason, when the material forming the first release layer 12-1 is mainly composed of silicone acrylate having polysiloxane as a main chain, the material forming the second release layer 12-2 is a second material. It is desirable to make the compounding ratio smaller than that of the first release layer 12-1.

The first release layer 12-1 and the second release layer 1
2-2 can also be formed using the same material.
In this case, it is necessary that at least the first release layer 12-1 and the second release layer 12-2 have different release properties. In the present embodiment, the release component contained in the first release layer 12-1 is contained more than the release component contained in the second release layer 12-2. The release component is, for example, a silicone-based, wax-based, or olefin-based material contained in a release ink. For example, the first release layer 12-
The first and second release layers 12-2 can be formed of a UV-curable offset ink. When the release component is a silicone acrylate having a polysiloxane main chain, the release component is the first release layer. 12-1 is the second release layer 12
It is preferably contained 1.5 to 10 times more than -2. Further, the thickness of the first release layer 12-1 is 3 to 10
μm, the thickness of the second release layer 12-2 is preferably about 0.5 to 3 μm.

The resin layer 13 includes a release layer 12 (second release layer 1).
It is a sealing layer formed on the back surface of 2-2) to prevent the adhesive layer 14 from exhibiting adhesiveness when the substrate 11 or a part thereof is peeled off. The resin layer 13 can be formed by printing or coating a UV ink or a synthetic resin such as a vinyl acetate resin, an acrylic resin, or a polyurethane resin. The resin forming the resin layer 13 is at least one of vinyl chloride (PVC) resin, polystyrene (PSt) resin, acrylic resin, rubber resin, polyester resin, urethane resin, and melamine resin. Is preferably a main component. The thickness of the resin layer 13 is not particularly limited, but is usually 0.5 to
It is 30 μm, preferably about 5 to 15 μm.

The adhesive layer 14 is a layer formed below the resin layer 13 and enables the resin layer 13 to be adhered to an adherend such as luggage. The adhesive layer 14 is preferably made of an acrylic adhesive, a natural rubber adhesive, a synthetic rubber adhesive, a silicone rubber adhesive, or the like. Coating amount of adhesive layer 14
The coating thickness is not particularly limited, but preferably, the coating amount is 0.1 to 50 g / m ² and the coating thickness is 0.1 to 50 μm.
m. The adhesive strength of the adhesive layer 14 to an adherend such as luggage needs to be greater than the pseudo-adhesive strength of the display substrate 11, and may be appropriately adjusted according to the adherend.

The barrier layer 15 has a repelling property when the material of the resin layer 13 is applied, and also has a pressure-sensitive adhesive layer 14.
And a layer that weakly adheres to the surface, and is formed in the portion A where peeling is to be started. The barrier layer 15 can be formed by letterpress printing of a resin such as organic silicone. The thickness of the barrier layer 15 is not particularly limited, but is usually 0.1 to
It is about 5 μm, preferably about 1 to 2 μm. Here, it is necessary to control the level of the release layer 12-2 on the outermost surface so that the release layer 12-2 adheres to the resin layer 13. Even if the resin layer 13 is patterned, the release layer 12-2 and the adhesive provided next It has the property of adhering to the layer 14. In addition, the resin layer 13
In order to become the outermost surface after peeling, it is desirable that the flat surface be a flat surface.For this gravure printing, reverse coating, other commas and grades, etc. Easy to put out. That is, by providing the barrier layer 15 as in the present embodiment, all the requirements can be easily satisfied. In particular, many forms (business forms) are continuous and have an endless diameter of inch, but if the barrier layer 15 is printed at the same time as the pattern, registration can be facilitated. When the resin layer 13 is provided by gravure printing, (1) plate production cost is high,
(2) If the printing is off-line, it is not practical because the control is difficult even if the circumference is the same.

The material for forming the barrier layer 15 is such that a release component such as a silicone-based, wax-based, olefin-based, or fluorine-based material is added to the above-described release ink for forming the release layer 12 by a factor of two to three times. It can be obtained by adding a certain excess. That is, when the release component of the release material forming the release layer 12 and the release component of the barrier material 15 are the same material, the weight content ratio of the release component is such that the release component of the barrier material is smaller than the release component of the release material. It is also preferable to increase the number.

The barrier layer 15 is made of the laminated release label 1
It is provided at a portion A where the separation is to be started, which is an end of the portion D where the separation is to be performed. The portion A to be peeled is preferably rectangular, triangular, semi-circular or similar in shape and easy to manufacture, and has a necessary and sufficient shape as a trigger for peeling. In addition, 3 including all solid patterns
It is preferable that it is made of 0% or more of a shade or a dot pattern having a width of 3 mm or less. The reason for this is that if it is too wide, there is the problem of inadvertent peeling, and
This is because the resin layer 13 cannot be repelled. In this embodiment, an example of all solid patterns is shown by triangles.

The lengths ax and ay of the portion A to be peeled off are:
The length is preferably 10 mm or less with respect to the peeling direction x and the orthogonal direction y.

The length ax, a
y is on the line E to be cut, such as a perforation, or 2 thereof.
mm, the part to be peeled d
It is desirable to have a length of 30% or more of the length of x.
The reason for this is that although it is easy to peel off, it does not peel off carelessly, and it is considered that it is unlikely to break or break due to local stress.

Next, the method of manufacturing the laminated release label according to the present embodiment will be described in the order of steps. First, on the back surface of the display substrate 11, a UV using silicone acrylate as a release component was used.
After offset printing of a silicone-based resin to a thickness of about 0.1 to 3 μm, the resin was sufficiently cured by a UV lamp to form a first preprint release ink layer 12-1a. Then, the same resin as that of the first preprint release ink layer 12-1a is coated on the back surface of the first preprint release ink layer 12-1a with a thickness of 0.1%.
After coating to about 3 [mu] m, the first release layer 12-1 was formed by sufficiently curing with a UV lamp to form a second preprint release ink layer 12-1b.

Next, on the back surface of the first release layer 12-1, a UV silicone resin having a reduced release component, which is different from the resin forming the first release layer ~
After coating to a thickness of about 3 μm, the coating was sufficiently cured by a UV lamp to form a second release layer 12-2. Here, a silicone-based barrier material for forming the barrier layer 15 is applied to a portion A where peeling is to be started by a letterpress printing to a thickness of 1 μm.
m. Then, a resin material such as polyurethane is applied to the back surfaces of the second release layer 12-2 and the barrier layer 15 by adding 1
0 μm was applied to form a resin layer 13. At this time, the barrier layer 15 repels the resin layer 13 and substantially covers the second release layer 12.
-2 only. Lastly, an adhesive made of an acrylic ester was applied at a thickness of 15 μm to form an adhesive layer 14, thereby manufacturing the laminated release label 10 of the present embodiment.

According to the first embodiment, since the barrier layer 15 is provided in the portion A where the separation is to be started, the resin material is repelled even if the resin layer 13 is applied over the entire surface, and the barrier layer 1 is removed.
5 is not applied. Therefore, the resin layer 1 can be interposed between the release layer 12 and the release layer 12 without being printed in the shape of the portion A to be started.
A portion without 3 is formed, a trigger for peeling can be easily produced, and peeling can be surely performed. In addition, since the barrier layer 15 is normally weakly bonded to the pressure-sensitive adhesive layer 14, there is no inadvertent detachment and the reliability is high.

(Other Embodiment) FIG. 2 is a view showing another embodiment of the laminated release label according to the present invention. In addition,
In the following embodiments, portions that perform the same functions as in the above-described first embodiment are denoted by the same reference numerals, and overlapping drawings and descriptions will be appropriately omitted. In the laminated release label 10B of FIG. 2 (A), the peeling start portions B are vertically elongated slender triangles at two locations on the left and right. In addition, the printing of the portion B where the separation is to be started is formed by a 2 mm stripe which is within 3 mm. Furthermore, the width bx in the peeling direction
Is set to 8 mm which is within 10 mm. FIG. 2 (A)
In the case of, even in the case of multi-row progression (many rows of the same label are manufactured in a row), the adjacent narrow triangles are arranged in a nested state, so that the total width of both is substantially equal, and the resin material is Can be repelled stably. If not in the nested state, there is a place where the total width of the barrier layer becomes large, and the resin material cannot be repelled, and the resin material remains on the barrier layer and may be bonded. .

In the laminated release label 10C shown in FIG. 2B, the peeling start portion C is provided with a triangular shape (C1) at the lower right corner in the same manner as in the first embodiment, and at the upper side and the right side, It was provided in the shape of a key (C2), and also in the shape of a ring (C3) around the punch hole for the file. In addition, the printing of the peeling start scheduled portion C was provided so as to be a dot pattern. In the case of FIG. 2B, since there is no resin layer in a processed portion such as a file hole, there is no fear of breakage due to processing unevenness.

The present invention is not limited to the embodiments described above, and various modifications and changes are possible, which are also within the scope of the present invention. (1) For example, the release layer has been described as an example of two layers, but may be one layer.

[0034]

As described above in detail, according to the present invention, since the barrier layer is provided at the portion where the peeling is to be started, even if the resin layer is applied over the entire surface, the resin material is repelled and the barrier material is repelled. Because it is not applied on the layer, even if it is not printed in the shape of the part where peeling is to be started, there is a part without a resin layer between the peeling layer and a trigger for peeling can be easily produced, It can be peeled off reliably. Also,
Usually, the barrier layer is weakly bonded to the pressure-sensitive adhesive layer,
There is no accidental drop-out and high reliability.
