No. 46992, U.S. Pat.
Nos. 699408, 2855156, 324062
No. 1, No. 3,526,598, and No. 3,728,262, basically containing a magnetic fine powder and a binder as main components, together with a dispersant, a lubricant, an antistatic agent, and a water retention agent. A magnetic recording layer is provided by coating, orientation, and drying on a support such as paper. Such magnetic recording sheets are widely used for cashless cards used in banks, telephones, etc., transportation tickets, coupons, commuter passes, unit voting tickets, expressway pass tickets, etc. It is expanding.

[0003] In recent years, prepaid cards have attracted attention due to the rapid spread of telephone cards and orange cards. The spread of such magnetic recording materials is that the information storage capacity of the magnetic recording layer is large, that the written information is easily and accurately read, and that the information can be easily processed by an automatic ticket gate or a vending machine. And is effective for labor saving.

A conventional magnetic ticket sheet is formed by applying a magnetic paint containing a magnetic powder and a binder to one side of a paper or resinous sheet to form a magnetic recording layer, and performing magnetic orientation in the longitudinal direction of the sheet. The roll is set into a roll by slitting, and the roll is set in a ticketing machine and cut to be longer than the roll width at the time of ticketing, so that it is practically used as a necessary magnetic card. That is, the application direction of the magnetic paint is the direction of the magnetic orientation X,
This is the longitudinal direction of the roll.

However, in this method, the number of cards that can be taken from one magnetic sheet roll cannot be increased due to the restriction of the winding outer diameter of the magnetic sheet roll from the space of the ticket vending machine, and the roll needs to be replaced frequently. There was a problem.

Japanese Patent Publication No. 5-51966 discloses that two types of magnetic cards having one side of a common size but different sizes of the other side can be issued from the same magnetic ticket sheet roll as needed. A sheet structure and a method of manufacturing the same are disclosed. In the same publication, as shown in FIG. The purpose of the present invention is to provide a magnetic ticket sheet that can be issued by sharing a ticket A. For this reason, the magnetic recording layer is provided with a fixed magnetic orientation angle with respect to the longitudinal direction of the roll-shaped sheet so that the magnetic ticket sheet can exhibit the same magnetic characteristics in the width direction and in the longitudinal direction. With respect to the longitudinal direction of the magnetic ticket sheet, the angle is limited to ± 5 ° around 45 ° or 135 °, that is, 40 ° to 50 ° or 130 ° to 140 °.

[0007] However, in this method, the A ticket also has the B
In order to ensure that the ticket has the same magnetic characteristics, the squareness ratio, which is one of the important magnetic characteristics, is reduced, and sufficient magnetic strength cannot be obtained. It is necessary to apply a large amount of magnetic paint. As a result, not only the cost of raw materials is increased, but also the magnetic properties such as resolution and overwrite properties are deteriorated, and the length of a roll accommodated in a cassette having the same outer diameter is shortened.

[0008]

SUMMARY OF THE INVENTION According to the present invention, the number of issued tickets can be greatly increased without changing the outer diameter of the winding, and the magnetic orientation can be performed in the longitudinal direction of the sheet without increasing the coating amount of the magnetic paint. An object of the present invention is to provide a magnetic recording sheet exclusively for a cross ticket capable of obtaining a predetermined magnetic output as compared with a magnetic sheet, and a method for manufacturing the same.

[0019]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a magnetic recording sheet and a method of manufacturing the same according to the present invention will be described in detail.

The feature of the magnetic recording sheet and the method of manufacturing the same according to the present invention is that the orientation direction of the magnetic material is 10 ° to 39 ° or 14 ° with respect to the CD direction at the time of manufacturing the magnetic recording sheet.
1 ° to 170 °, preferably 20 ° to 35 ° or 14
5 ° to 160 °, and the squareness ratio in the CD direction is 0.6
By setting it to 5 to 0.90, preferably 0.70 to 0.85, a high magnetic output can be obtained even when a cross-cut ticket is issued such that the CD direction at the time of manufacturing the magnetic recording sheet is the longitudinal direction of the card. A magnetic card having the same can be obtained.

In order to obtain such an excellent magnetic recording sheet, a magnetic paint containing a ferromagnetic material and a binder is applied to one surface of the support while the support is advanced in the machine running direction. While the coating layer of the magnetic paint from the time of application to the drying zone is in an undried state, the orientation of the dried magnetic material is changed by the magnetic field orientation device while holding the back surface of the support with a canvas. Magnetic orientation such that the angle is 10 ° to 39 ° or 141 ° to 170 ° with respect to the CD direction of the coating machine, and the squareness ratio in the CD direction of the coating machine is 0.65 to 0.90. It is to make it.

The magnetic field orientation device used in the present invention may be a permanent magnet type, a solenoid type or a combination thereof, but using a permanent magnet is more advantageous in terms of angle adjustment, quality control, cost and the like. Using this permanent magnet as a repulsion facing magnetic field orientation device, the center of the gap between the vertically facing magnets is run together with the support and the canvas supporting the support, and the magnetic field orientation device is rotated in parallel with the canvas. The orientation angle of the magnetic material is adjusted.

If the orientation angle of the magnetic material in the present invention is larger than 39 degrees, the magnetic reproduction output at the time of ticket issuance is not sufficient, and it is difficult to ensure the reliability at the time of high-speed ticket issuance. A magnetic orientation angle smaller than 10 degrees is a preferable direction from the magnetic characteristics,
Since a huge magnetic alignment device is required and the width of the support that can pass through is extremely narrow, economic efficiency is poor and it is not practical.

When the support is paper, the solvent of the magnetic paint penetrates the paper support and curls. In particular, when the solvent is an aqueous solvent, it penetrates the paper support to increase the curl, and the support absorbs the aqueous solvent, thereby increasing the concentration of the coating layer, decreasing the mobility of the magnetic material and reducing the magnetic orientation. Can't do enough. Therefore, if the paper is used as a support and the degree of Stekigt sizing is 100 seconds or more based on a basis weight of 160 g / m ² , the absorption of the aqueous solvent by the support is reduced, curling is suppressed, and the magnetic material is easily removed. The decrease in the mobility is also suppressed, and the effect of the magnetic alignment treatment is sufficient.

In the present invention, the coating width of the support is 700
If it is less than mm, it is easy to set a magnetic orientation angle for obtaining a relatively large magnetic reproduction output, but the economical efficiency in actual operation is poor and it is not practical. Also, if the solvent of the magnetic paint easily penetrates the support, curl will occur and the magnetic properties cannot be maintained uniformly at the center and edges in the width direction because the support cannot be kept horizontal. The thickness of the body paint layer may be different. Therefore, the coating width of the support is set to 700
By keeping the thickness at least mm, curling can be suppressed by the weight of the support and the magnetic paint layer, and a magnetic recording sheet having uniform magnetic properties in the width direction can be obtained.

In the present invention, when the support is paper, preferably, the Steckigt sizing degree is 160 g in basis weight.
/ M ² and 100 seconds or more, and the coating width of the support is 7
It is preferable to use a support having a thickness of 00 mm or more. The basis weight of the support is usually 60 to 300 g / g to secure the necessary mechanical strength and economical winding length at the time of ticketing.
m ² is preferred, and a more preferred range is 100 to 20
0 g / m ² .

The magnetic powder used in the magnetic recording sheet of the present invention includes, for example, γ-iron oxide, γ-iron oxide modified with cobalt, chromium oxide, barium ferrite and strontium ferrite. Furthermore, 5-19
A hexagonal ferrite magnetic powder composed of fine particles suitable for a high-density magnetic recording medium manufactured by the “method of manufacturing a hexagonal ferrite magnetic powder for magnetic recording” disclosed in JP-A-66-66 may be used.

The magnetic paint mainly comprising a magnetic powder and a binder used in the magnetic recording layer according to the present invention is prepared by using either an aqueous solvent or an organic solvent solvent. Is also economically favorable. In addition,
If necessary, an antifoaming agent, a thickening agent, a curing agent, a penetrant, an antiblocking agent, a water repellent, a waterproofing agent, and the like can be used.

Examples of the aqueous binder include starches such as oxidized starch and etherified starch, hydroxyethyl cellulose, methyl cellulose, polyvinyl alcohol, and the like.
Water-soluble binders such as polyacrylamide, carboxymethylcellulose, gum arabic, casein, gelatin, and polyethylene oxide, and various latexes such as polyurethane, vinyl chloride, polyacryl, and styrene butadiene can be used.

As a coating apparatus for applying the magnetic paint for the magnetic recording layer in the present invention, an air knife coater, a gravure coater, a roll coater, a rod coater, a curtain coater, a die coater, a lip coater, a blade coater, and the like are used.

In the present invention, in order to prevent the magnetic properties from deteriorating due to the permeation of the magnetic recording layer into the paper layer, a permeation preventing layer can be provided between the support and the magnetic recording layer, if necessary.
The composition of the permeation preventing layer is typically a water-soluble polymer such as polyvinyl alcohol or starch, or a synthetic resin such as polyethylene or polypropylene, but is not limited in the present invention.

As the support of the magnetic recording sheet of the present invention, a sheet-like substance such as paper mainly composed of wood fibers or a non-woven fabric mainly composed of wood fibers or synthetic fibers can be mentioned. Wood pulp used in the case of paper is used. Is NBKP, LBKP, N
In addition to BSP, LBSP, GP, TMP and the like, used paper pulp is used, and used alone or in combination as needed.

At the time of producing the paper as a support used in the present invention, the degree of stiffchite sizing is adjusted by taking into account methods such as size press and coating as necessary to reduce the variation in magnetic output. Furthermore, after the paper making process and the magnetic recording layer coating process, a machine calendar,
A flattening device such as gross calender, super calender, brushing, or the like can be used.

The thermal transfer recording layer, which is the recording layer of one preferred embodiment of the magnetic recording sheet of the present invention, is generally classified into two types: a fusion type thermal transfer recording type and a sublimation type thermal transfer type. The recording layer may be of any type, and these known recording layers may be applied.

Example 5 In Example 1, a magnetic field orientation treatment was performed so that the orientation angle of the magnetic substance was 10 degrees with respect to the CD direction of the coating machine, and a roll paper having a width of 92 mm was prepared. The magnetic output and the squareness ratio in the longitudinal direction were measured for a 92 mm note paper, and the data shown in Table 1 were obtained. However, since the paper edge hits the pole of the magnetic alignment device,
The width of paper that can pass must be narrowed, and productivity has decreased.

Example 6 The procedure of Example 3 was repeated, except that the paper support was 60 seconds based on a basis weight of 160 g / m ² , and the data shown in Table 1 were obtained. However, since the degree of Stekigt sizing was as low as 60 seconds based on a basis weight of 160 g / m ² , the concentration of the coating layer was increased, and the magnetic alignment effect in the magnetic alignment treatment step was reduced.

Comparative Example 1 In Example 1, a magnetic field orientation treatment was performed so that the orientation angle of the magnetic substance was 90 degrees with respect to the CD direction of the coating machine, and a roll paper having a width of 92 mm was prepared. The magnetic output and the squareness ratio in the longitudinal direction were measured for a 92 mm note paper, and the data shown in Table 1 were obtained.

A paper roll was prepared, and the magnetic output and the squareness ratio in the longitudinal direction were measured as a 53 mm × 92 mm note paper, and the data shown in Table 1 were obtained.

Comparative Example 5 In Example 5, the orientation angle of the magnetic material was further changed to the CD of the coating machine.
I tried to align the magnetic field at 7 degrees to the direction.
Not only does the paper edge hit the column of the magnetic alignment device, but the concentration of the magnetic paint layer when passing through the magnetic field alignment process changes in the width direction,
The possible paper width must be further reduced, and the application width is 680m
m, the curl increased, and the magnetic properties varied in the width direction, resulting in a decrease in productivity.

Reference Example 1 In Example 1, a magnetic field orientation treatment was performed so that the orientation angle of the magnetic substance was 90 degrees with respect to the CD direction of the coating machine, and a 53 mm wide roll paper was prepared. The magnetic output and the squareness ratio in the longitudinal direction were measured for a 92 mm note paper, and the data shown in Table 1 were obtained. This is a so-called vertical ticket, which is used as a standard for reproduction output.

[0052]

[Table 1]

By using the magnetic sheet roll exclusively for the cross-cut ticket, a single magnetic sheet roll having the same outer diameter could issue 70% more tickets than the vertical cut ticket. In addition, the orientation of the magnetic substance in the magnetic recording layer is 10 ° with respect to the width direction of the coating machine.
° to 39 ° or 141 ° to 170 °, and
Since the squareness ratio in the width direction of the coating machine was 0.65 to 0.90, no trouble due to magnetic properties occurred as in the conventional magnetic ticket magnetically oriented in the longitudinal direction. Also,
If the support is paper, the Stechig sizing degree is 16 basis weight.

Multiple magnetic tickets can be taken from a single magnetic sheet roll. In addition, since the magnetic layer has a high magnetic strength in the width direction of the coating machine, a desired magnetic strength can be obtained without increasing the application amount of the magnetic layer. In addition, in the manufacturing method, the support after applying the magnetic paint is horizontally supported by a canvas and passed through a magnetic orientation step and a drying step, so that the support does not run out and uniform magnetic properties are obtained in the entire width direction.
