DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a correction tape, and more specifically, it conceals a portion to be corrected such as a typographical error,
The present invention relates to a correction tape whose surface can be modified.

[0002]

2. Description of the Related Art Conventionally, there has been known a correction liquid for concealing a portion of a document to be written correctly when a typographical error such as a letter or a symbol occurs in the written matter. This correction liquid can be applied by a so-called pen touch method in addition to the application with a brush, but it is difficult to apply the correction liquid evenly due to the viscosity change of the correction liquid over time, and the correction characters etc. However, there is an inconvenience that it cannot be described in.

By the way, recently, a white hiding layer and an adhesive layer which are peelable from the substrate layer are sequentially laminated on one surface of the tape-shaped substrate layer, and the hiding layer and the adhesive layer are formed. A transfer tape for correction, on which the correction characters and the like can be written on the surface of the concealing layer, has been developed by transferring to the uncorrected portion. This correction transfer tape is accommodated in a predetermined holder so that it can be wound up, and can be transferred by partially exposing the tape from the holder and moving the exposed portion while pressing the exposed portion against the corrected portion. .

[0004]

However [0007], in the known transfer tape, and multi emitting a transfer failure such as causing cracks or fissures in the hiding layer transferred, in this case,
There is an inconvenience that the corrected characters cannot be displayed neatly on the surface of the hiding layer.

Moreover, when writing characters or the like on the surface of the hiding layer, the hiding layer is often scraped off with a pen tip, and it is often difficult to maintain the desired correction effect. Further, the transfer of the concealing layer and the adhesive layer is performed by aligning the tape portion exposed from the holder with the surface of the paper, and there is also a disadvantage that it is easily transferred to a portion that does not require correction.

[0006]

OBJECTS OF THE INVENTION The present invention was devised by focusing on the disadvantages of the conventional example, and an object thereof is to enable a correction tape to be directly attached to a correction portion without using a transfer system. The purpose of the present invention is to provide a correction tape in which the surface of the tape can be used as a correction surface, and the correction characters can always be described stably.

Another object of the present invention is to reduce the thickness of the tape and minimize the step between the attached tape and the paper surface so that the contour of the tape appears as a shadow during copying. Not to provide a correction tape.

[0008]

In order to achieve the above-mentioned object, the correction tape according to the present invention is made by kneading aluminum.
A base material layer containing a non-translucent resin film and this base material
Adhesive layer laminated on one surface of the layer, and the other of the base material layer
And a white printing layer laminated on the surface of the .

Further, the correction tape according to the present invention is oxidized.
Base material layer made of non-translucent resin film by kneading titanium
And an adhesive layer laminated on one surface of the base material layer,
Has a predetermined surface roughness laminated on the other side of the base material layer
A structure including a coat layer is also adopted.

[0010]

[Action] In the state where the sticking the modified tape to the paper as an object to be repaired portions Fixed should therefore modified non-translucent resin film itself such as characters completely hidden to the surface side of the base layer character It becomes possible to describe such as. At this time, the surface side of the base material layer becomes white to be compatible with the color of the plain paper to avoid the color tone difference between the two. Further, it constitutes a base layer of a resin film
And for that, it is possible to form a tape thickness as a whole in the order of microns, a possibility that Projects shadows during copying step be minimized with the paper after the tape adhering can be prevented.

The base material layer in the present invention is polyester,
It can be molded with a resin film made of polypropylene, polyethylene, nylon, acetate or the like, or a composite material thereof. The thickness of the base material layer is 10 μm
It is set in the range of ˜80 μm. This is because if it is less than 10 μm, it becomes difficult to handle, while if it exceeds 80 μm, there is a high possibility that a shadow will be generated at the time of copying due to a step after attachment. As the white pigment, can be preferably used titanium oxide emissions or the like, the amount added is Ru is set arbitrarily within a range capable of imparting non-light-transmitting resin film. Contact name adhesive layer that includes a certain elasticity, i.e. natural rubber or the like having the adhesiveness to an adherend such as paper, known materials are used, the adhesive layer of the cellophane tape or mending tape A layer thickness similar to that of adhesive tape is sufficient.

[0012]

Embodiments of the correction tape according to the present invention will be described below with reference to the drawings.

Example 1 In FIG. 1, a correction tape 10 is made of polyester.
It is made of a resin film formed by kneading aluminum.
And a lower surface which is one surface of the base material layer 11
Adhesive layer 13 laminated on the other side of the base material layer 11
And a white printing layer 15 provided on the surface
Have been. Here, the base material layer 11, the adhesive layer 13, and the white color
The thickness of each layer of the printing layer 15 is 20 μm, 5 μm, 3 μm
Each is set.

When the correction tape 10 was attached to a portion to be corrected using plain paper, the character to be corrected could be completely hidden and the surface side could be seen as the same color as the plain paper. . In addition, it is possible to write characters and the like on the surface of the base material layer 11 without any inconvenience, and further, the entire thickness of the correction tape 10 is reduced, so that a step difference from a sheet can be suppressed. When this was tested using a copying machine (NP2020, manufactured by Canon Inc.) with densities of 1 to 10 (where 1 is the thinnest and 10 is the darkest), a copy was made up to a density of 8 without causing any shadow to appear. We were able to. Further, when a character was written across the correction tape 10 and the plain paper, it was possible to write a very smooth and beautiful character by suppressing the above-mentioned step.

Example 2 As the base material layer 11 shown in FIG. 2, a resin film formed by kneading titanium oxide into polyester was used, and the layer thickness was set to 40 μm. While providing the same adhesive layer 13 as in Example 1 on this, a coat layer 16 having a layer thickness of 5 μm was provided on the surface of the base material layer 11. The coat layer 16 is formed by adding a white powder having a particle size of 0.1 to 1 μm to a volatile solvent.

Also in this embodiment, the same result as in the above-mentioned embodiment can be obtained, and further, when the character written with a pencil is rubbed on the surface, no bleeding occurs at all.

Comparative Example A hiding layer in which titanium white is mixed is laminated on one surface of a woodfree paper having a layer thickness of 85 μm, and a colorant layer and a pressure-sensitive adhesive layer are sequentially laminated on the hiding layer so that the total thickness is 100 μm.
I got the correction tape. This was pasted on the area to be modified on plain paper and the characters were entered.

In this comparative example, it was possible to conceal the portion to be corrected and to enter the correction character normally. However, when copying with the copying machine of Example 1, the density of 4 or more resulted in a shadow of the tape contour. The result was copied. Further, as compared with the above-mentioned embodiment, the layer has a thickness as a whole, the number of steps with respect to the paper surface was large, and it was not possible to neatly write the characters across the correction tape and the paper surface.

[0019]

EFFECTS OF THE INVENTION According to the correction tape of the present invention, it is possible to completely eliminate the inconveniences such as transfer failure or scraping off of the concealing layer at the time of writing correction characters, which are seen in the transfer tape. a film as a base layer, can be suppressed thickness as a whole in the base layer thus gaining concealing effect of the corrected portion, whereby also be exposed as a shadow tape contour on paper that it is copied Not at all. In addition, since the level difference between the correction tape and the paper surface is small, it is possible to ensure the easy writing state even when characters are written across the correction tape and the paper surface.
