[Technical field to which the present invention pertains] The present invention relates to a microcapsule magnetic recording sheet. More specifically, the present invention relates to a microcapsule magnetic recording sheet. And a microcapsule magnetic recording sheet.

[0002]

2. Description of the Related Art Conventionally, magnetic recording sheets or recording plates on which characters and pictures can be written using a magnetic pen have been known. More specifically, a honeycomb recording medium such as a dispersion medium, a magnetic powder and a coloring pigment has been known. A magnetic recording plate of a honeycomb type enclosed in a chamber, a microcapsule magnetic recording sheet containing a dispersion medium, a magnetic powder, a coloring pigment, and the like are known. In particular, in recent years, a microcapsule magnetic recording sheet has a clear recorded image. In addition, they are widely used because they can be miniaturized. Magnetic recording sheets using the microcapsules include those using spherical magnetic powder as magnetic powder and those using flat magnetic powder. In each of these microcapsule magnetic recording sheets, characters and pictures can be recorded and erased on a recording surface using a magnetic pen, and these can be repeated.

[0003]

[Problems to be Solved by the Invention] However, the above-mentioned microcapsule magnetic recording sheet is often used for a fixed purpose, and is usually used on a desk. Recently, however, there has been a strong demand for users to attach them to walls, lockers, sills, etc. according to the purpose of use, or to attach them to notebooks, notebooks, cards, etc. for their own use. The present inventors have conducted various studies and found that the problem can be advantageously achieved by providing an adhesive on the back surface of the microcapsule magnetic recording sheet. The present invention has been made here. Therefore, the problem to be solved by the present invention is that the microcapsule magnetic material can be used by sticking it to the desired location, and it is not necessary to separately prepare paper on which the usage, precautions and advertisements are printed. To provide a recording sheet.

[0004]

The object of the present invention is to provide a microcapsule magnetic recording sheet comprising a recording / display transparent sheet, a microcapsule coating layer, an adhesive layer and a release member in this order. In the present invention, it is achieved by a microcapsule magnetic recording sheet characterized in that at least the surface of either the transparent sheet or the release member is printed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited thereto. FIG. 1 is a cross-sectional view showing the microcapsule magnetic recording sheet of the present invention. FIG. 2 is a sectional view showing a microcapsule used in the present invention. FIG. 3 is a cross-sectional view of a microcapsule magnetic display sheet in which the exposed surface (back surface) of the release member of FIG. 1 is printed. Further, FIG. FIG. 3 is a cross-sectional view of the capsule magnetic display sheet. FIG. 5 is a plan view of the printed matter viewed from the release member side in the present invention. In FIG. 1, the microcapsule magnetic recording sheet I of the present invention comprises a transparent sheet 1, a microcapsule coating layer 2, an adhesive layer 6, and a release member 5 in this order. In FIG. 2A, a microcapsule 3p contains a dispersion medium 3c, a magnetic powder 3a, a color pigment (particularly a white pigment is preferred) 3b, and the like. The magnetic powder 3 may be spherical 3a or flat 3d as shown in FIG. The support for the release member 5 is not particularly limited, and paper, plastic, or the like is used. However, paper is preferable in consideration of cost, environment, and the like.

In use, the microcapsule magnetic recording sheet I is obtained by peeling off the release member 5 and affixing it to a wall, a door, a locker, a desk, a stand, or the like as required, and recording therewith using a magnetic pen. Can be. Also, the record can be erased. If necessary, it can be peeled off and affixed to another place and used in the same way. When the spherical body 3a is used as the magnetic powder 3, erasing is usually performed by applying a magnet to the back surface. However, even when the spherical body 3a is used, erasing can be performed from the recording surface side, especially from the front side. In such a case, erasure can be surely performed by using a rare earth magnet and moving the magnet while floating above the recording surface. When the flat powder 3d is used as the magnetic powder 3, characters, pictures, etc. drawn on the recording surface are erased from the recording surface side. When the spherical body 3a is used as the magnetic powder 3 and erased by applying a magnet to the back surface, it is usually attached or stored in a notebook or the like, and if necessary, erased by applying an erasing magnet from the back surface side.

[0007] Such a microcapsule magnetic recording sheet I can be used by attaching it to a card, a notebook, or the like in a small size. Further, in FIG. 3, the microcapsule magnetic recording sheet II can be printed on the surface of the release member 5 on the back surface, and for example, how to use the sheet II, a precautionary statement, an advertisement, etc. are printed in advance. (See FIG. 5). In particular, in the case of usage, precautionary statements, etc., there is an advantage that it is not necessary to attach these printed sheets again. Further, FIG. 4 shows a case where printing is performed on the surface of the transparent sheet 1. In this case, it is preferable to print an advertisement. At this time, the usage and precautions may be printed on the release member 5 on the back surface.

[0008]

[Effects of the Invention] According to the present invention, the use of the sheet can be performed not only by attaching the release member to a desired place, but also by using the sheet on the surface of the release member. It is possible to print notices, advertisements, and the like, so that there is no need to separately attach a paper on which the notices are printed.
