Description

[Detailed Description of the Invention] This invention relates to a magnetic and thermal recording sheet on which a magnetic material layer and a magnetic material layer for magnetic records are applied. Widely used for tickets, etc.

Demand for recording media for patterns visible to the human eye is increasing, but it is difficult to read the recorded contents into devices such as combinators.

Further, as other recording media, magnetic recording sheets such as magnetic cards and the like provided with a magnetic layer for magnetic recording such as magnetic tape are also widely known. This has the advantage that it is easy to read the contents recorded on a recording medium by using the characteristics of magnetic recording into a computer, etc. In recent years, 7-1-K for thermal recording has been A sheet for magnetic and thermal recording, which is provided with a magnetic material layer for magnetic recording and has both a magnetic recording section and a thermal recording section, thereby combining the advantages of both a thermal control sheet and a magnetic recording sheet.・This kind of magnetic and thermal recording sheet! ・is a magnetic recording part (1) with a magnetic layer for magnetic recording and a magnetic recording part (1) for thermal recording as shown in Figure 1. It has a heat-sensitive recording portion (21) coated with a paint layer.

The method for manufacturing such a magnetic and heat-sensitive recording sheet is (a) by applying a magnetic material layer for magnetic distribution such as magnetic tape on a sheet-like substrate by a transfer method7, and then applying a heat-sensitive recording layer to the entire surface. A method of applying a heat-sensitive recording paint layer by applying a recording paint, (b) applying a heat-sensitive recording paint to the entire surface of a sheet-like base material and applying a heat-sensitive recording paint layer, and then V
A possible method is to apply a magnetic layer for magnetic recording such as C@air tape by a transfer method or the like. However, according to method (a) above, since the heat-sensitive recording paint layer is also present in the magnetic layer for magnetic recording, problems such as a decrease in the magnetic output of the magnetic layer for magnetic recording and concerns arise. . Stopped i: Itki (b)
According to the above method, it is not possible to apply heat when a magnetic layer for instantaneous recording such as a magnetic tape is formed on a coating layer for heat-sensitive recording by transfer, etc., and therefore the magnetic layer for magnetic recording does not adhere. In the meantime (3 degrees when the dog is formed), in the previous step (1) and (b), a magnetic tape or other magnetic tape was applied onto the heat-sensitive recording paint layer formed to a uniform thickness. Because the magnetic layer for recording is applied, the part of the magnetic layer for magnetic recording is more convex than the part of only the paint layer for heat-sensitive recording.
The difference in level between the IX part and the magnetic recording part is cleared.

Therefore, a problem arises in that a print edge appears in the heat-sensitive recording portion.

In order to eliminate the problem of front spacing, a method may be considered in which a heat-sensitive recording paint is applied to the entire surface of the sheet-shaped substrate and then a magnetic layer for magnetic recording is formed by a printing method. However, with this method, it is difficult to form a magnetic layer of sufficient thickness for magnetic recording, resulting in another problem of insufficient magnetic flux strength.

The present invention aims to provide a sheet I for magnetic and thermosensitive recording and a method for manufacturing the same, which do not have the above-mentioned problems.

That is, the magnetic and heat-sensitive recording sheet according to the present invention has a magnetic recording part (1) in which a magnetic material layer for magnetic recording is applied to the surface of a sheet-like base material and a heat-sensitive paint layer is applied, as shown in FIG. It has a heat-sensitive recording portion (21), and the area where the heat-sensitive recording layer 1'!! material layer is applied and the area where the magnetic layer for magnetic recording is applied are adjacent to the Buddha. In addition, the magnetic layer for magnetic recording is exposed on the surface, and there is no paint layer for heat-sensitive recording below the magnetic layer for magnetic recording.

The magnetic and thermosensitive recording sheet of the present invention is manufactured as follows.

First, as shown in FIG. 2, a transfer sheet is prepared in which a magnetic layer (4) for magnetic recording X'G4 is formed on a base material 131 for a transfer sheet, and an adhesive layer (5) is further formed thereon. .

The base material (3) for the transfer sheet is the magnetic layer (4) for magnetic recording.
It has good releasability, and is similar to paper or plastic sheets coated with a release agent to make it releasable. For magnetic recording (the magnetic material layer (1) may be magnetic tape, coated with a binder mixed with magnetic powder, or even formed by vapor deposition. Even if a magnetic material is vapor-deposited, the quality is high.

In addition, the adhesive layer (5) is a well-known heat-sensitive adhesive that is widely used when transferring magnetic tape to cards, etc.
It's good.

The transposed seam prepared in this way is used to form a magnetic recording part as shown in Figure 1. If it is a magnetic recording part, it should be in the form of a tape having the same width as the magnetic recording part.If it is in another shape, it should be in a shape suitable for the shape of the gas recording part to be formed.

Therefore, the surface structure of the transfer sheet and the [1] of the sheet-like base material described below.
When comparing the types of sounds, the sheet-like base material has a larger surface jet.

The transfer sheet prepared as described above is then used as a sheet-like base material as shown in FIG. 61-t,: (iτ The adhesive layer (5) is stacked on the inside B (the adhesive layer 1*(5) is applied to the magnetic recording layer at the opening of the magnetic recording layer)

Next, after drying the above-mentioned heat-sensitive recording paint, the base material (j) for recording sheet 1 is peeled off and removed.

In this case, as shown in FIG. 5, the heat-sensitive recording sheet applied on the base material (3) for the transfer sheet 1 and the heat-sensitive recording paint applied to the base material for the transfer seed are not removed. ni that thousand and one

It is also possible to create a continuous production line that includes the process of attaching the sheet 1 to the sheet 1-shaped base material. Calendering improves the surface smoothness of the product.

As explained above, the magnetic and thermal recording seal of the present invention
According to -, since there is no paint layer for heat-sensitive recording on two sides of the magnetic material layer for magnetic recording, there is no adverse effect on the magnetic properties.

Furthermore, according to the magnetic and heat-sensitive recording notebook according to the present invention, there is no heat-sensitive recording sheet below the magnetic layer for magnetic recording, and the paint layer for heat-sensitive recording and the magnetic layer for magnetic recording are in sheet form. Because they are formed on the base material, the level difference between the surface of the paint layer for heat-sensitive recording and the surface of the magnetic layer for magnetic recording is almost negligible in practical use. Printing defects rarely occur.

Furthermore, according to the present invention, there is provided a magnetic and thermal recording sheet on which a magnetic material layer for magnetic recording and a rough coating layer for thermal recording are applied, and which is of superior quality to conventionally known sheets. It can be easily manufactured.

The magnetic and thermosensitive recording sheet of the present invention may be manufactured in the form of a long sheet as shown in FIG. 6, or may be manufactured in individual sheets rather than in a long sheet, or may be manufactured in any other suitable form. .

The sheet of the present invention produced in a long shape can be used in any desired form, such as being processed into a card shape as appropriate.

Furthermore, embodiments in which the thermosensitive recording portion and/or the magnetic recording portion are provided on both sides of the sheet-like base H can also be implemented as necessary.
