Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a form paper on which a heat-sensitive coloring layer is formed.

[0002]

2. Description of the Related Art Optical read information such as a bar code is printed on a form paper (thermal paper) on which a thermosensitive coloring layer is formed by a thermosensitive printing apparatus. And this optical read information is
The data is read by the optical reader and used for required information processing.

[0003]

However, the form paper on which the heat-sensitive coloring layer is formed is liable to develop color even by frictional heat, and the surface of the form paper is subjected to shear stress during handling of the form paper. It is easy to cause coloring stains. In particular, if this coloring stain occurs in the information reading area where the print information read by the optical reading device is printed, the information may be erroneously read or the reading may not be possible. Further, even in a visible area where information is read visually, other than a print information reading area where information is read by the optical reading device, if coloring stains occur, characters and numbers are difficult to read. An object of the present invention is to eliminate the problems of the conventional configuration.

[0004]

According to the present invention, in a form paper having a heat-sensitive coloring layer formed thereon, a required surface of the heat-sensitive coloring layer is formed by a frictional heat reducing layer for suppressing the coloring of the heat-sensitive coloring layer by frictional heat. A form paper characterized by being coated.

In such a configuration, the required surface of the thermosensitive coloring layer refers to an information reading area where printing information read by the optical reader of the thermosensitive coloring layer is printed, or a visual recognition area where information is read visually. means. In the former information reading area, if coloring stains occur due to frictional heat, the information may be erroneously read or unreadable. By covering this with a frictional heat reduction layer, such erroneous reading or unreadableness is prevented. Is prevented. Further, even in the visual recognition area, it is possible to prevent difficulties in reading characters and numbers due to coloring stains.

[0006] By the way, when the friction heat reduction layer is coated, ink is hardly absorbed in the stamped area of the seal, the seal is not fixed, and the seal is stained or transferred to another paper surface. . Therefore, the imprint area is not covered with the frictional heat reduction layer. In this case, the thermosensitive coloring layer may not be formed.

Here, the frictional heat reduction layer is formed by a lubricant such as UVOP varnish (manufactured by T & K TOKA). Further, the glossiness of the frictional heat reduction layer is 2.5 to
8.5 (Gloss meter GMX manufactured by Murakami Color Research Laboratory)
) Is optimal. That is, in this range, it is possible to sufficiently improve the abrasion resistance and prevent the generation of heat due to friction.

[0008]

1 to 3 show a form sheet 1;
A thermosensitive coloring layer 2 having a large coefficient of friction, such as a thermosensitive coloring layer, is formed on the surface thereof. An information reading area 3 formed in a part of the thermosensitive coloring layer 2 has a bar code or the like read by an optical reader. The print information 4 is printed by the heat-sensitive printing device in a heat-sensitive manner. Also, on the other surface, a visual recognition area 5 where characters, numerals, and the like are printed by the same heat-sensitive coloring is provided. Further, a stamp area 6 is formed in which the seal is stamped. As shown in FIG. 1, the form paper 1 according to this configuration is bonded onto a label sheet 10 for a printer, and the label sheet 10 for a printer is caused to travel along a paper feed path of a thermal printing apparatus to thereby obtain an information reading area 3. , Required information is printed in the visual recognition area 5.

The required surface of the thermosensitive coloring layer 2 having such a structure is
The frictional heat reduction layer 7 for suppressing the coloring of the thermosensitive coloring layer due to frictional heat according to the main part of the present invention is coated. The friction heat reduction layer 7 is made of a photocurable OP varnish (UVOP varnish, T
& K TOKA) and the like.

FIG. 2 shows the manner in which the frictional heat reduction layer 7 is formed.
This will be described with reference to FIG. 2 and 3 show that the frictional heat reduction layer 7 is formed only in the information reading area 3. That is, the information reading area 3 can read the print information 4 by the optical reading device. However, a shear stress acts on the form paper 1 due to overlapping paper sheets and various other factors, and at that time, frictional heat is generated, and the heat-sensitive coloring layer 2 is colored. In particular, since the heat-sensitive coloring layer 2 has a large coefficient of friction, it is easy to develop a color. And this gives
The heat-sensitive coloring layer 2 produces coloring stains. However, if this stain occurs in the information reading area 3, the print information 4 becomes unclear, and when read by an optical reading device, erroneous reading or indecipherability may occur. Therefore, the information reading area 3
If the frictional heat reduction layer 7 is formed only in such a case, such a problem can be avoided.

FIG. 4 shows that the frictional heat reduction layer 7 is formed on the entire surface of the thermosensitive coloring layer 2 except for the imprint area 6.
That is, as described above, when the frictional heat reduction layer 7 is also formed in the stamping area 6, the frictional heat reduction layer 7 deteriorates the ink absorbency. ,
The imprint will not be fixed on the imprint area 6. For this reason, when a rubbing force is generated on the seal, the seal is diffused, becomes unclear, and stains other paper surfaces. Therefore, the friction heat reduction layer 7 is not formed on the imprint area 6.

FIG. 5 shows a structure in which the frictional heat reduction layer 7 is formed in the print information 4 and the visual recognition area 5 and is not formed in the stamp area 6. As described above, when the frictional heat lowering layer 7 is formed on the print information 4, reading error of the print information 4 can be prevented. Makes it difficult to read. Therefore, the frictional heat reduction layer 7 is also formed in the visual recognition area 5. On the other hand, in the imprint area 6, the frictional heat reduction layer 7 is not formed in order to fix the imprint.

As described above, in each configuration, at least the frictional heat reduction layer 7 is formed on the print information 4 and the frictional heat reduction layer 7 is not formed on the imprint area 6, and the information Reading and imprinting are not hindered.

In each of the above-described drawings, the frictional heat reducing layer 7 is not formed on the entire surface of the thermosensitive coloring layer 2 but is formed selectively. This selective formation can be easily performed by offset printing or the like. Further, where the color density is not desired to be reduced, printing such as reducing the thickness of the frictional heat reduction layer 7 and increasing the thickness of the other portions can be performed.

Incidentally, the frictional heat reduction layer 7 is formed of a lubricant such as a photocurable paint (eg, a photocurable OP varnish manufactured by T & K TOKA CORPORATION).

When the photocurable OP varnish is used as described above, the amount of the photocurable OP varnish can be set by using a gloss meter.
After the application, it can be set to rise to about 2.5 to 8.5.

Here, the smoothness was tested when an OP varnish was applied to a sheet of paper on which a heat-sensitive coloring layer was formed, and when no OP varnish was applied. The application amount of the OP varnish can be set with a gloss meter, and here, the gloss is set to be about 2.5 to 8.5 as described above.

According to the test results, OP was added to the thermosensitive coloring layer.
By applying the varnish, even if a shear stress is applied to the surface, frictional heat is hardly generated, and as a result, the heat-sensitive coloring layer 2
However, no color is formed.

[0020]

According to the present invention, at least a required surface of the heat-sensitive coloring layer is coated with a frictional heat reducing layer in a form paper having a heat-sensitive coloring layer formed thereon. Can be prevented. In particular, when the information reading area where the print information read by the optical reader of the thermosensitive coloring layer is printed is covered with the frictional heat reduction layer, the reading error of the information is prevented. In addition, when the visual recognition area where information can be read visually is covered with the frictional heat reduction layer, characters and numerals become clear. Further, by removing the frictional heat reduction layer in the stamped area of the seal, there is an excellent effect that the seal can be fixed well.
