Abstract

PROBLEM TO BE SOLVED: To select an affixing method depending on an installation place, and more conveniently display a memo paper or the like by a method wherein on one surface of a magnetic layer, an adherent layer and a release sheet are laminated in order, and on the other surface of the magnetic layer, a recording layer is laminated. SOLUTION: A recording layer 1 is a layer to record ruled lines, characters and images such as pictures, and an image forming layer is solely provided, or laminated on a film, a paper or the like. A magnetic layer 2 can hold memoranda bound with a clip or the like by using the drawing force of a strong magnetic body. Also, when this recording material is affixed at a place showing ferromagnetism, the magnetic layer 2 can take place of an adherent layer 3. The adherent layer 3 is a layer which is provided to be affixed to a required place, and an adhesive comprising an acrylic based resin or the like can be used. Then, a release sheet 4 prevents the adhesive from sticking to an unnecessary place. By this method, the affixing by the magnetic layer 2, not by the adhesive, to a place which shows a ferromagnetism, becomes possible, and a re-affixing can be easily performed.

The recording layer 1 is a layer for recording images such as ruled lines, characters, pictures, and the like, and has an image forming layer alone or laminated on a film or paper.

As a recording method, printing may be used, but in addition to printing, a method of making and exposing and developing a plate, and electrophotography, ink jet printing, handwriting, and the like, when a small amount is manufactured without the need for plate making Is preferred.

The image forming layer includes a photosensitive layer having a layer in which the exposed portion or the other portion is dyed or colored by exposure / development treatment or a layer which dissolves or swells and peels off.
PPC, laser printer, or a toner easy-adhesion layer suitable for electrostatic transfer recording such as an electrostatic plotter, an ink-receiving layer capable of forming an image by inkjet recording such as an inkjet printer, a heat-sensitive transfer recording layer, a pencil or a water-based pen,
An image-forming layer using an oil-based pen, a whiteboard writing layer that can be written with a felt pen of an aqueous or oil-based ink, and the written portion can be erased by wiping can be used.

Further, a protective layer may be arbitrarily formed on the image.

Further, as the recording layer 1, a layer in which a recording layer is newly laminated after an image is formed on the image forming layer can be used. For example, an image is formed with a photosensitive layer of a recording material having a photosensitive layer, and a recording layer having a transparent whiteboard writing layer is newly laminated. By doing so, the recording layer 12 in which the fixed information is recorded in advance
Then, a recording layer 1 having a recording layer 11 for recording variable information is obtained (FIG. 2).

The magnetic layer 2 is for attracting a ferromagnetic material, for example, a material that is easily attracted to a magnet such as a clip, and can hold a memo bound by a clip using the attraction force. Yes (Figure 3). Further, in the case of sticking to a place showing ferromagnetism, the adhesive layer can be replaced.

As the magnetic layer 2, any material can be used as long as it can attract a ferromagnetic material and maintain a suction force.

Such a material may be a sheet obtained by dispersing magnetic powder in a resin, a sheet provided with a resin layer in which the magnetic powder is dispersed, or a commercially available material. It can also be suitably used.

The adhesive layer 3 is a layer provided to be attached to a necessary place.

As the adhesive layer 3, an adhesive made of an acrylic resin, a urethane resin, a polyester resin, a silicone resin or the like can be used.

It is also possible to use a matrix adhesive layer or a re-adherable adhesive layer that can be bonded to an adherend without using an instrument, and has a thickness of 5 to 100 μm.
The degree is appropriate.

The matrix adhesive layer has an adhesive layer formed in an uneven shape with an adhesive to provide a gap for easily releasing air to the adhesive layer, so that it can be stuck to an adherend without using any equipment. Become.

The release sheet 4 prevents the adhesive from sticking to unnecessary places. By adopting this configuration, it is possible to attach the magnetic layer instead of the adhesive to a location exhibiting ferromagnetism, and it is possible to easily attach the magnetic layer again.

As the release sheet 4, a sheet obtained by appropriately releasing the surface of a plastic film such as polyester, polyethylene, polypropylene or the like or paper or the like with silicone or the like can be used. Although the thickness of the release sheet 4 cannot be determined unconditionally depending on the material constituting the release sheet, it is generally 4 to 4 in consideration of workability and the necessity of not hindering the holding of the recording material by the magnetic layer 2. 200 μm, preferably 2
The range of 0 to 100 μm is preferred.

The recording layer 1 and the magnetic layer 2 are adhered to each other with an adhesive or an adhesive. Alternatively, the recording layer 1 or the magnetic layer 2 may be used as a base material and the other layer may be directly applied to be laminated.

As the pressure-sensitive adhesive or adhesive, any pressure-sensitive adhesive or adhesive usually used for bonding resin materials or the like can be used. For example, known pressure-sensitive adhesives such as acrylic, polyester, rubber, and silicone-based adhesives can be used. Adhesives or adhesives can be used. Such a pressure-sensitive adhesive layer or adhesive layer is used in a thickness of about 3 μm to 100 μm.

When each of the above-mentioned layers is formed by coating, the above-mentioned respective layers are made into a coating material and applied by a suitable coating apparatus such as a bar coater, a gravure coater, a curtain coater, a roll coater, and a blade coater. -It can be formed by drying.
