Description

  The present invention relates to a label paper for an adhesive label, and more particularly to a label paper capable of forming a laminate layer on the surface of a label when used.

Label paper is known in which a label paper and a film are laminated so that a user can write a character or the like on the surface of the label paper and then apply an adhesive film to the surface of the label paper to form a laminate layer.
For example, a conventional label paper has a structure in which a first release paper, a film, a second release paper, and a label paper are laminated in this order, and a pair of the same laminated structure is provided symmetrically with a folding line provided on the first release paper. Label paper of the same shape is placed. Then, in use, after writing letters etc. on one label paper, remove the other second release paper and the label paper, fold it from the fold line, stick the film on the label paper, release the fold and laminate To obtain a labeled label. (For example, refer to Patent Document 1).

  There is also label paper in which a film, release paper, and label paper are laminated in this order. In this method, a label is first attached to a target object after characters or the like are written on a label sheet for use. Subsequently, the film remaining on the label paper is removed, and a laminated layer is formed on the label. (For example, see Patent Document 2).

Japanese Utility Model Publication No. 7-5167 Japanese Utility Model Application Laid-Open No. 6-23066

Due to the recent development of computer-related technology, there is a demand for users to print characters and images on the label surface using a printer.
The above-described conventional label paper having a four-layer laminated structure has a large thickness, and it is difficult to pass the paper with an ordinary printer. Also, half of the label paper is discarded, which is uneconomical.

Next, in the second conventional example, it is necessary to attach a film after attaching the label paper to the object. Labels can be applied to curved surfaces such as the spine of books, vertical surfaces such as cabinet doors, and even slopes. After the label is attached to such a surface, it is difficult to attach an adhesive film thereon, and lamination failure such as wrinkling of the film may occur.
Further, it is difficult to accurately position the pressure-sensitive adhesive film in accordance with the label surface in such a place, and a displacement between the label paper and the film occurs.

Therefore, an object of the present invention is to obtain a label paper with a laminate film suitable for printing using a normal printer. Another object of the present invention is to provide a label sheet that can perform a laminating operation at an appropriate working place such as a desk. Still another object of the present invention is to obtain a label sheet that can be easily positioned during a laminating operation.
Other objects and advantages of the present invention will become apparent from the following description of the present invention.

The label paper of the present invention comprises a pressure-sensitive adhesive layer A formed on a film, a release paper adhered on the pressure-sensitive adhesive layer A, and a pressure-sensitive adhesive layer B formed on the release paper. The release paper has a release treatment layer a on a surface in contact with the pressure-sensitive adhesive layer A, and the release paper is in contact with the pressure-sensitive adhesive layer B. A label paper having a release treatment layer b on its surface, wherein Fa is the release force between the film and the release paper, and Fb is the release force between the label paper and the release paper. Label paper that satisfies).
Fa <Fb (1)
The label paper of the present invention, after filling in the necessary information on the label paper, peel off the laminate of the label paper and the release paper from the label paper (hereinafter, this laminate is referred to as "label before coating"), turn it over, and turn it over to the label paper. It is to press the remaining film and laminate the label paper.

  A laminated structure (hereinafter sometimes referred to as a differential peeling structure) in which the peeling force (Fa) between the film and the release paper was made weaker than the peeling force (Fb) between the label paper and the release paper was adopted. That is, the peeling force (Fa) between the film and the release paper is made relatively light, and the peeling force (Fb) between the label paper and the release paper is made relatively heavy. For this reason, the label before coating can be easily and integrally peeled off from the label paper.

The label paper of the present invention has a three-layer structure of a film, a release paper, and a label paper, so that the total thickness of the label paper can be reduced, and printing can be performed by a normal printer. In particular, the label paper of the present invention is suitable for printing with a printer because there is no step over the entire surface of the label paper.
Further, the laminating operation by peeling, turning over, and pressing the label paper before coating onto the fill surface can be performed at an appropriate work place.

  In addition, since the adhesive surface is not exposed on both sides of the label before coating, any part of the label paper before coating can be held or changed during lamination work, making it easy to perform positioning and other operations. I can do it. Also, except for the second label described in detail below, the label piece and the laminated film have the same shape, the film does not protrude from the label, the appearance around the attached label is maintained, and the label with the laminated portion is small. You can get the paper. Further, the laminate can improve the water resistance of the label and the print applied to the label.

In one embodiment of the label paper of the present invention, the total thickness of the label paper may be 300 μm or less.
General inkjet printers and laser printers used in offices and homes can pass a printing medium having a thickness of about 300 μm. According to the present embodiment, it is possible to obtain label paper that can be printed using such a printer. Further, the label paper of the present invention can be a thicker label paper. In particular, it is not necessary to consider the thickness of the label paper for handwriting.

In one embodiment of the label paper of the present invention, the surface state of the release treatment layer a and the surface state of the release treatment layer b may be different.
In the present embodiment, the different peeling structure of the label paper is realized mainly by differentiating the peeling process of the front and back surfaces of the release paper. In this way, the adhesive strength of the pressure-sensitive adhesive layer, particularly the pressure-sensitive adhesive layer B, can be designed relatively freely. For example, if the pressure-sensitive adhesive layer B has a relatively low adhesive strength, it will be a laminate label that can be easily peeled off after adhesion, and the use of the label will be expanded.
For adjusting the adhesive strength of the pressure-sensitive adhesive layer B, various means for realizing the different peel structure described later by the difference of the pressure-sensitive adhesive layer can be applied.

In one embodiment of the label paper of the present invention, the label paper and the release paper are cut out with the same contour line, and the line portion of the film facing the contour line is cut leaving some non-cut portions. And a first label area divided into a certain shape by the contour line may be provided.
In the present embodiment, the number of the first label areas provided on one label sheet may be single or plural. There is a lower limit on the size of a print medium that can be passed by a general printer, and it is usually about a postcard made by government. According to the present embodiment, even if the label is smaller than the lower limit of paper passing through the printer, printing can be performed by the printer. In other words, even a small label piece can be printed and printed using a normal printer.

The outline of the blanking process may be an independent single line surrounding the label area, or a part of the outline may be common to the outline of the label paper. For example, when two label areas are provided on a label sheet, the cut line may be a single straight line.
When a plurality of first label areas are provided, the film area after peeling off the uncovered label has at least one side thereof adjacent to the label paper on which the label paper still remains. When the pre-coated label is turned over and pressed against the film, the remaining first label area serves as a guide for positioning.

In one embodiment of the label sheet of the present invention, a plurality of first label areas may be formed on the label sheet, and the plurality of first label areas may be provided at intervals.
If there is an interval between the plurality of first label areas, the film surface after peeling off the label before coating is divided by the label paper left on the interval. When the pre-coated label is turned over and crimped to the film, the placed label paper serves as a guide for positioning and further facilitates positioning.

In one embodiment of the label paper of the present invention, the first label region may have a square-like shape.
A square-like shape is a square, a rectangle, a square with rounded corners, a rectangle with rounded corners, a shape with some of these sides outward, a shape with some of these sides inward, or its sides A part or the whole of a wavy line refers to a square or a rectangle.
Since the label is generally similar in shape to a rectangle, this embodiment provides a more convenient label paper.

In one embodiment of the label paper of the present invention, the first label area is an index paper, and the label paper is partially formed on a straight line connecting midpoints of two facing long sides of the square-like shape. It may be cut off.
In the present embodiment, the middle line of the first label area is at least partially cut, and the work of folding the label into two when attaching the index label becomes easy. Since the index sheet is folded in two and attached, it is very difficult to attach the laminate film after attaching the label in the conventional example. Therefore, this is a preferred use example of the present label paper to be pasted after the lamination work is performed at an appropriate work place (for example, on a desk).

In one embodiment of the label paper of the present invention, a mark indicating the long side of the square-like shape may be provided on the label paper surface between the first label areas.
When peeling the uncoated label from the label paper of the present invention, it is preferable to peel it off from the linear portion of the first label area. When the first label region has a square-like shape, the preferable peeling position is a part on the long side. Therefore, a mark indicating the long side is attached and the peeling position is clearly indicated, so that the label paper becomes more convenient to use. Here, when the first label area is a square or a substantially square, the long side in the present embodiment means any one of the four sides.

In one embodiment of the label paper of the present invention, the label paper and the release paper are punched with the same contour line, and the film is formed into a film with a shape surrounding the contour line outside the contour line. A line may be provided, and a second label area divided into a certain shape by the contour line may be provided.
The second label according to the present invention is laminated with a film that is one size larger than the label, and is attached to the object by using an adhesive applied to the back surface of the label itself and an adhesive applied to a portion of the film protruding from the label. Can be Thus, the label is more protected from water and gas ingress. Also, the adhesion of the label becomes stronger.

Further, in removing the release paper remaining on the second label piece separated after lamination, it is easy to apply a force in the bending direction to the label piece using the protruding film portion as a fingerhold. The work of removing paper becomes easy.
As described in the embodiment of the label paper provided with the first label area, in the present embodiment, the number of the second label areas provided on one label paper may be single or plural. Is also good.

Further, the film-cutting processing line may be an independent single line surrounding the second label area, or a part thereof may be common to the outline of the label paper.
In this embodiment, the film area after the uncoated label is peeled off is surrounded by the label paper remaining on the label paper. When the label before coating is turned over and pressed against the film, the existing label paper serves as a reference for positioning.

In one embodiment, the label sheet of the present invention is a label sheet provided with a plurality of second label areas, the second label area having a square-like shape, and the film surrounding the plurality of second label areas. The blanking lines may be provided at an interval from each other.
A square-like shape is a square, a rectangle, a square with rounded corners, a rectangle with rounded corners, a shape with some of these sides outward, a shape with some of these sides inward, or its sides A part or the whole of a wavy line refers to a square or a rectangle.
Since the label is generally similar in shape to a rectangle, this embodiment provides a more convenient label paper.
Further, even after the label area is removed, a part of the film remains on the label paper, so that the effect of easily removing the adjacent label area can be obtained.

  The embodiments of the present invention described above can be implemented in combination as much as possible.

According to the present invention, it is possible to obtain a label paper with a laminate film suitable for printing using an ordinary printer in an office or home. Further, according to the present invention, it is possible to obtain a label paper that can be easily laminated.
In a preferred embodiment of the present invention, it is possible to obtain a label paper in which the positioning of the label and the film during the laminating operation is easy.

In the present invention, the peeling force (Fa) between the film and the release paper is adjusted by changing the surface shape of the release treatment layer a and the adhesive force of the pressure-sensitive adhesive layer A (in some cases, simultaneously, the surface shape of the film). Can be. Preferably, Fa is adjusted by changing the surface shape of the release treatment layer a.
The peeling force (Fb) between the label paper and the release paper can be adjusted by changing the surface shape of the release treatment layer b and the adhesive strength of the pressure-sensitive adhesive layer B (in some cases, at the same time, the surface shape of the label paper). . Preferably, Fb is adjusted by changing the surface shape of the release treatment layer b.

  The pressure-sensitive adhesive layers A and B used in the present invention are pressure-sensitive adhesives. As such a pressure-sensitive adhesive, a known pressure-sensitive adhesive (for example, an acrylic, rubber, or urethane-based pressure-sensitive adhesive) can be used. Preferably, it is an acrylic pressure-sensitive adhesive.

The peeling force Fa between the film and the release paper and the peeling force Fb between the label paper and the release paper satisfy Expression (1).
Fa <Fb (1)
Preferably, Fb is 1.5 times or more of Fa, more preferably 1.5 times or more and 10 times or less, further preferably 1.5 times or more and 5 times or less, and most preferably 2 times or more. 4 times or less. When the relationship between Fa and Fb is within this range, the label before peeling can be easily peeled off, and the degree of freedom in designing the adhesive force of the adhesive layer A and / or the adhesive layer B is improved.
Here, the peeling forces (Fa, Fb) are the median of the measured values measured by the T-type peeling method according to JIS-Z-0237 (the same applies hereinafter).
As a specific example, Fa is in the range of 70-300 mN / 100 mm, Fb is in the range of 140-800 mN / 100 mm, and is a value satisfying the above-described expression (1). The above numerical ranges are merely examples, and do not limit the technical scope of the present invention.

The difference peel structure uses (1) different kinds of pressure-sensitive adhesives in forming the pressure-sensitive adhesive layer A and the pressure-sensitive adhesive layer B,
(2) use a different amount of adhesive
(3) The application area of the adhesive is different (for example, one is applied over the entire surface, and the other is applied in a fine strip shape, a fine scattered shape, a fine checkered shape, etc.),
(4) mixing fine particles in the adhesive;
This is realized by such means.

The release paper used in the present invention is usually one obtained by subjecting a paper surface to a release treatment. As the release treatment, a silicone resin coating, a fluororesin coating, or an amine-based release agent coating can be used. Further, a surface embossing process, a bratting process, a processing method of adding fine particles to a coating agent, or the like can be used.
The difference peeling structure is used for forming the peeled surface a and the peeled surface b.
(1) using different kinds of coating treatment agents,
(2) The coating amount of the coating agent is different.
(3) The application area of the coating agent is different (for example, one is applied over the entire surface, and the other is applied in a fine band, finely scattered, or fine checkered pattern).
(4) The finished smoothness is changed by embossing or the addition of fine particles.
This is realized by changing the surface state of the release treatment layer by such means as above.
Further, the difference peel structure can be realized by using the difference in the adhesive strength of the pressure-sensitive adhesive layer and the difference in the surface state of the peeling-treated surface in combination.

The punching process in the case where the first label region is provided refers to a process in which the stacked body having the stacked structure can be cut and the region surrounded by the cutting line can be peeled. The blanking line is provided for the purpose of peeling the uncoated label from the label paper in label area units.
Although the label paper and the release paper are cut by the punching process, these are supported by the film and the adhesive layer A, and the label paper and the release paper maintain the shape of the label paper. Here, the film is also provided with a cutting line, but a part of the cutting line has a non-cut portion. Therefore, the film retains the shape of the label paper, and the release paper and label paper supported by the film also retain the shape of the label paper.

  One or more anchor portions may be provided on the cutting line of the punching process. The anchor portion is a portion where a very short line is connected without being cut on the cutting line, and has a role of assisting in holding the shape of the label paper. An example of the distance between the anchor portions is 0.2 mm. In order to print and print on label paper with a printer, it is preferable to provide an anchor portion on the blanking line.

In the case where the first label area is provided, a cutting line leaving a part of a non-cut portion is provided in a line portion of the film facing the punching line. The cut line of the film is provided for separating the film from the label paper after the laminating process.
"Cut line leaving some non-cut portions" means a cut line (for example, a micro sewing line) in which cuts and uncuts at short intervals are alternately continued, a relatively long cut and a relatively short uncut. Cutting line that is alternately and regularly continuous (for example, dashed-dotted line, two-dotted dashed cutting line), and a relatively long cut and a relatively short uncut alternately and continuously cut line (having an anchor portion Cutting line). Among these, a cutting line in which a relatively long cut and a relatively short uncut are alternately or irregularly continuous is preferable. The length of the short chain line and the length of the anchor portion are preferably 0.2 to 0.4 mm.

Furthermore, when the outline of the punching is an independent single line surrounding the label area and the label area has a square-like shape, at least one non-cut portion is provided on each of a pair of sides facing the outline. Preferably, it is provided.
Thus, the film is kept integral until the non-cut portion is separated by applying an appropriate external force.

In the present invention, the shape of the label area can be a square, a circle, an ellipse, a polygon, a doll, an outline of a building, or the like. Furthermore, a plurality of label regions having the same shape can be provided on one label paper, and label regions having different shapes can be mixed.
The interval between the label areas may be provided all around the label area, may be provided only in the vertical direction, or may be provided only in the horizontal direction. More preferably, the interval is provided all around the label area.

In the present invention, the index paper refers to a heading paper piece attached to a side portion of the paper such as a notebook, a ledger, and a file.
In the index sheet of the present invention, the partial cutting line provided on the line connecting the intermediate points of the long sides may be at least partially cut, and may be entirely cut. Only the label paper is cut along the cutting line, and the release paper portion corresponding to the line is not cut. The cut label paper is supported by the release paper and the adhesive layer B, and the shape of the label paper and the label before coating are maintained. Further, in the label piece after the lamination process, the cut label paper is supported by the film and the adhesive layer A, and the shape of the label piece is maintained.

  The place where the mark indicating the long side of the square-like shape is marked is the space between the label areas, and is the surface of the label paper (the back side of the surface in contact with the adhesive layer B). The mark can be an appropriate means such as an arrow, a square, a circle, and coloring along the side.

  Regarding the second label area, the distance between the second label area and the film-cutting processing line surrounding the second label area is usually 1 mm to 5 mm, preferably 2 mm to 4 mm, more preferably 2.5 mm to 3.5 mm. Within this interval range, the operation of separating the laminated label area becomes easy. In addition, the interval between the second label contour line and the film cutting line may be the same interval over the entire circumference, or may be different intervals. According to the arrangement of the second label area provided on one piece of label paper, the distance can be changed between left and right and up and down of the second label area. It is also optional to change the interval on one side, particularly for reasons such as design using a patterned film.

Further, the interval provided between the film cutting lines is usually 2 mm to 5 mm, preferably 2.5 mm to 3.5 mm. With this spacing, the work of separating the laminated label area becomes easy.
The film cutting line may be a continuous cutting line or a cutting line leaving some non-cut portions. A cutting line that leaves some non-cut parts is a cutting line that alternates cuts and uncuts at short intervals alternately (for example, a micro-sewing line), and a relatively long cut and a relatively short uncut alternately. Cutting line that is regularly continuous (for example, dash-dot line, dash-dot line cutting line), cutting line that is irregularly continuous with a relatively long cut and a relatively short uncut (a cutting line having an anchor portion) ).
The punching process provided on the label paper and the release paper is the same as the punching process described for the first label area. An anchor portion may be provided in this punching line, similarly to the punching described for the first label area.

As the label paper used in the present invention, coated paper, high quality paper, kraft paper, finely coated paper, thermal paper, and other papers can be used. Further, a synthetic resin film subjected to an ink receiving process can also be used.
When printing with an inkjet printer, it is preferable to use paper dedicated to the inkjet printer. Since a normal ink jet printer uses a water-soluble ink, it is desirable to laminate the printed surface in order to protect the printed surface, which is a preferred application field of the present invention.
As the label paper, white paper and colored paper can be used. Further, vertical, horizontal, and grid-like ruled lines may be printed on these in advance. Further, preliminary printing such as an underline, a company name, a library name, and a trademark may be performed.

  The film is a see-through protective film. Therefore, a transparent, translucent, colored film, patterned film, or the like can be used. The material is usually an olefin or ester resin. Examples of the olefin-based resin include polyethylene, polypropylene, polystyrene, and polyvinyl chloride. Examples of the ester-based resin include polyethylene terephthalate (PET) and polybutylene terephthalate. PET is preferred from the viewpoint of dimensional stability, transparency and the like.

  Hereinafter, the label paper according to the present invention will be further described with reference to examples. The dimensions, materials, shapes, relative positions, and the like of the members and portions described in the embodiments of the present invention are not intended to limit the scope of the present invention only to them unless otherwise specified. Rather, it is merely an illustrative example.

  FIG. 1 is a schematic sectional view of a label sheet according to the first embodiment. The label paper 1 includes a film 11, an adhesive layer A (12) formed on one side of the film 11, a release paper 13 adhered thereon, an adhesive layer B (17) formed thereon, The label paper 18 is attached to the label paper 18. The pressure-sensitive adhesive layer A (12) is formed on the entire surface of one side of the film 12. The pressure-sensitive adhesive layer B (17) is formed on the entire area of one side of the label paper 18. The film 11 is a transparent PET film. The release paper 13 has a release treatment layer a (15) on the surface facing the film 11. The release paper 13 has a release treatment layer b (16) on the surface facing the label paper. The release treatment layer is formed by applying a silicone resin solution to the release base paper 14.

The amount of the silicone resin applied to the release treatment layer a (15) is larger than the amount of the silicone resin applied to the release treatment layer b (16). The pressure-sensitive adhesive layer A (12) is a solvent-type acrylic pressure-sensitive adhesive. The pressure-sensitive adhesive layer B (17) is an emulsion-type acrylic pressure-sensitive adhesive.
With the above configuration, the peeling force (Fa, Fb) is mainly determined by the peeling treatment layers (15, 16). Since the release treatment layer a (15) has a larger amount of applied silicone resin than the release treatment layer b (16), the peeling force between the release paper 13 and the adhesive 12 is less than the peeling force between the release paper 13 and the label paper 18. Lighter compared. That is, the difference peeling structure of the label paper 1 is realized mainly by the difference in the surface shape between the peeling treatment layer a and the peeling treatment layer b.

In this embodiment, Fa is 170 mN / 100 mm, and Fb is 500 mN / 100 mm.
The label paper 18 is paper for use in an ink jet printer.
The thicknesses of the film 11, the release paper 13, and the label paper 18 are 25, 100, and 100 μm, respectively, and the total thickness of the entire label paper is 270 μm.

In the figure, reference numeral 31 denotes a first label area, which is surrounded by the outline 19. The outline 19 is a blanking line, the label paper 18 is cut by a line 20, and the release paper 13 is cut by a line 21. In addition, the film 11 is cut along a line 22 corresponding to the contour line 19, leaving an anchor portion. (The line 22 is shown as a broken line for the purpose of explanation. In actuality, cut and uncut cross sections appear.) The length of the anchor portion is 0.2 mm.
The film can be continuous and retain the shape of the entire film by the anchor portion. Although the label paper 18 and the release paper 13 are cut, since they are supported by the film 11 via the adhesive layers A and B, the overall shape is maintained.

FIG. 2 is a front view of the label paper 1. The label paper 1 of the present embodiment has twelve first label areas 31 surrounded by the outline 19. The first label areas 31 are arranged at intervals (30a, 30b, 30c) from each other. The first label area 31 is an index label. Its shape is a square-like shape (a square with a rounded rectangle and a concave at the midpoint of the long side). The length of the long side of the outer shape of the first label region 31 is indicated by an arrow 33.
Reference numeral 35 denotes a cutting line provided in the label area. The cutting line 35 is provided on a straight line connecting the midpoints 36a and 36b of the long sides 32a and 32b of the first label area. The cutting line 35 is obtained by cutting only the label paper, and the line portions of the release paper 13 facing the cutting line 35 are connected.

Next, how to use the label paper 1 will be described with reference to FIGS. 1, 2 and 3 as necessary.
First, a character 41 is written in the first label area 31 of the label paper 18 by means of a printer, handwriting, or the like.
Next, the label before coating (the label paper 18, the laminate of the adhesive layer B (17) and the release paper 13) in the first label area 31 is peeled off. Since the first label area 31 is punched and the label paper and the release paper are cut along the outline, the peeling can be easily performed. In addition, since the label paper has a differential peeling structure, when a peeling force is applied, the peeling treatment layer a (15) and the pressure-sensitive adhesive layer A (12) are peeled.

By this peeling, a laminate of the adhesive layer A and the film 11 remains in the label area of the label paper 1. The laminate 42 is surrounded by spaces 30a, 30c, and the like. The pre-coated label that has been peeled off is turned over, and the label paper printing surface is pressed against the remaining laminate 42. At this time, the label before peeling is positioned with reference to the intervals 30a, 30c and the like. 43 is a label before covering turned upside down.
The film 11 is laminated on the label paper printing surface via the pressure-sensitive adhesive layer A by the reverse / pressure bonding. Next, the film 11 is separated from the label sheet 1 according to a cutting line provided on the film surface. In the figure, reference numeral 44 denotes a label area from which the film has been separated, which is hollow.

  Thus, a laminated index label is completed. After removing the release paper 13 remaining on the label piece, the pressure-sensitive adhesive layer B is exposed, and the index label is stuck in a folded state with a part of the sheet at the sticking position sandwiched. At the time of folding in two, the cutting line 35 serves as a guide for the bending line.

FIG. 4 is a front view of the label sheet 1 according to the second embodiment. The laminated structure of the label paper 1 is the same as that of the label paper described in the first embodiment.
The label paper 1 of the present embodiment has nine first label areas 311 surrounded by the outline 191. The first label areas 311 are arranged at intervals (30d, 30e) from each other. The first label area 311 becomes a label. Its shape is rectangular.
The contour line 191 is subjected to the same punching processing as in the first embodiment.

In the figure, reference numeral 34 denotes a mark indicating the long side 321 of the first label area 311. The mark 34 indicating the long side is provided at the interval (30d) of the label area. The mark 34 indicating the long side is printed on a label sheet.
The method of using the label paper 1 of the present embodiment is the same as the method described in the first embodiment. However, when the label before coating is peeled off from the label paper 1 by using the mark 34 indicating the long side as a guide, the peeling can be performed more easily.

FIG. 5 is a schematic sectional view of a label sheet according to the third embodiment. The laminated structure of the label paper 1 is the same as that of the label paper described in the first embodiment, and the same members are denoted by the same drawing numbers.
In the figure, reference numeral 51 denotes a second label area, which is surrounded by a contour line 52. The outline 52 is a blanking line, the label paper 18 is cut by a line 53, and the release paper 13 is cut by a line 54.

The film 11 is punched by a film punching line 56 that overlaps a film outline 55 surrounding the outside of the outline 52. In this example, the film cutting line 56 is a continuous cutting line.
These punching processes are, for example, after preparing the label paper 1 having a laminated structure, cutting the label paper 18 and the release paper 13 by inserting a sword shape from the label paper 18 side surface of the label paper 1 and cutting the label paper 1 from the film 11 side surface. This can be performed by cutting the film 11 with a sword shape.

FIG. 6 is an explanatory front view of the label paper 1. The label paper 1 of this embodiment has nine second label areas 51 surrounded by an outline 52. The second label area 51 is slightly larger than the outline 52 and is surrounded by a film outline 55 surrounding the outline 52. (The film outline 55 appears on the back surface of the label paper 1 and does not appear on the front surface, but is illustrated in the front surface explanatory diagram for the purpose of explanation. In addition, since it is a continuous cutting line, it appears as a solid line on the back surface. The film outline 55 (shown in broken lines for purposes) overlaps the film cut line 56.
The interval between the outline 52 and the film outline 55 is such that the interval between the short side 52a of the outline and the short side 55a of the film outline (indicated by an arrow 61) is 3 mm, and the long side 52b of the outline and the film outline are determined. The interval between the long sides 55b (indicated by the arrow 66) is 3 mm. The distance between adjacent film contour lines is 3 mm on both the short side (shown by arrow 62) and the long side (shown by arrow 67). Further, the distance between the outline of the label paper 1 and the outline of the film (indicated by arrows 63 and 68) is 3 mm.

Next, how to use the label paper according to the third embodiment will be described.
First, characters are written in the second label area 51 of the label paper 18 by means of a printer, handwriting, or the like.
Next, the label before coating (the label paper 18, the laminate of the adhesive layer B (17) and the release paper 13) in the second label area 51 is peeled off. Since the label area 51 is punched and the label paper and the release paper are cut along the outline, the peeling can be easily performed. In addition, since the label paper has a differential peeling structure, when a peeling force is applied, the peeling treatment layer a (15) and the pressure-sensitive adhesive layer A (12) are peeled.

By this peeling, a laminate of the adhesive layer A and the film 11 remains in the label area of the label paper 1. The pre-coated label that has been peeled off is turned over, and the label paper printing surface is pressed against the remaining laminate.
The film 11 is laminated on the label paper printing surface via the pressure-sensitive adhesive layer A by the reverse / pressure bonding. Next, when the second label area is pushed in the direction of the back side of the label paper, the film 11 is separated from the label paper 1 according to the film removal processing line 56 (line overlapping the film outline 55).
As described above, since the laminated index label is completed, the release paper 13 remaining on the second label piece is removed.

FIG. 7 is an explanatory diagram showing an operation of removing the release paper 13 from the second label piece. As shown by the arrow 71, a part of the second label piece is sandwiched between fingers, and at the same time, the outline of the film 11 is pushed and bent in the direction of the arrow 72. Due to this force, a part between the release paper 13 and the label paper 18 (indicated by an arrow 73) is partially released. The label is changed and the release paper 13 is removed from the partial release portion 73.
Thereafter, the label piece is attached to the target object by the adhesive layer B exposed from the label piece and the adhesive layer A exposed from the film surface.

  The label paper according to the present invention can be used, for example, as an adhesive label paper.
