A whiteboard is a rigid substrate with a surface made of ceramic or synthetic resin that makes it easy for marking pen ink to adhere to it, giving it writing properties, but it is also processed to prevent the ink from penetrating, giving it erasability. ing.

る。However, ceramics are not easy to manufacture;
The methods of painting and baking synthetic resin onto the surface of the substrate also have low productivity and are both very expensive. In addition, a writing layer formed by processing a plastic sheet with a cured resin and pasting it onto the surface of a substrate is used, but this is also expensive. Furthermore, magnetic sheets are known in which magnets are attached to erasable writable sheets, but these are limited to places where they can be pasted where there is a magnetic effect.

層表面が黄変する欠点がある。[0005] Thermosetting resins such as melamine resins and unsaturated ester resins and ultraviolet curable resins are used as synthetic resins to form the writing layer of whiteboards. The stain resistance and hardness are insufficient, and erasability deteriorates with repeated use. Although ultraviolet curable resins have sufficient stain resistance and hardness, they have the drawback that the photopolymerization initiator and photosensitizer contained in the paint decompose, causing yellowing of the surface of the writing layer.

う。[0006] Furthermore, it is necessary that the surface of the writing layer has excellent smoothness; if a sufficiently smooth surface is not formed, erasability will be poor. Particularly when trying to erase handwriting that has been left for a long time after writing, the marking ink dyes and pigments that have entered the recesses of the writing surface and dried cannot be easily wiped off, and cannot be erased unless cleaned with water or a solvent. I won't be able to do it.

However, with paper with a normal writing surface, it is difficult to erase the letters after one use, and with regular tack paper, it is difficult to use and handle, as the paper tears when peeled off after use, and adhesive remains on the pasted surface. If you fail, cleaning afterwards will be difficult.

。[Function] As a result of intensive research in response to the above-mentioned demands, the present inventors provided a writing layer of electron beam curing resin on the surface of a specific base material sheet with excellent smoothness, and created a writing layer on the back surface of this sheet. The present invention was completed by providing a specific adhesive layer.

It is important that the surface has excellent smoothness and is below cmHg. If it exceeds 20 cmHg and the smoothness is poor, the coating amount of the writing layer must be increased, which is unfavorable from the quality of writability and erasability, as well as from the operational and economic aspects.

If it is below cmHg, a general base sheet may be used, such as a film sheet of polyester, polypropylene, polyethylene, polyvinyl chloride, polyvinylidene chloride, polycarbonate, polyamide, polystyrene, or a composite sheet thereof, laminated paper, coated paper, etc.
Undercoated paper, single-sided bleached kraft paper with good smoothness, etc. are used. Particularly, in applications where low cost and ease of use are desired, coated papers such as cast coated paper and art coated paper are preferred from the viewpoint of processability and price.

ている各種の型式や方式の照射装置を用いても良い。If the amount of curable paint applied is too small, sufficient stain resistance and hardness will not be obtained, and if it is too large, the base sheet will be distorted and curling will occur during curing.
The thickness is preferably 1 to 10 μm, particularly preferably about 1 to 10 μm. For electron beam irradiation, an electrocurtain type electron beam irradiation device is preferably used, but the present invention is not limited to this, and various commonly used types and systems of irradiation devices may be used.

は貼り付けてもすぐ剥がれ落ちたり、均一に付かずふく
れが出たりするおそれがある。また一方５００ｇを越え

ため、接着力の規定は重要である。In the present invention, an adhesive layer having an adhesive strength of 30 to 500 g to a stainless steel plate by the 180 degree peeling method specified in JIS-Z-0237 is provided on the back side of the writing layer sheet. If the adhesive strength is less than 30 g, there is a risk that the adhesive will peel off immediately even if it is pasted, or that it will not stick evenly and may blister. On the other hand, if the adhesive strength is as high as 500 g, it will not be possible to re-peel the adhesive as desired, so it is important to specify the adhesive strength.

定する必要がある。[0020] The adhesive force can be adjusted within a range suitable for the intended use by selecting and blending the adhesive, tackifier, and auxiliary agent. It is also possible to adjust the adhesive strength by mixing fillers such as various particles. The coating amount of the adhesive layer is 5 to 30 g/m2, more preferably 10 to 25 g/m2.
It is adjusted within the range of m2. Since the amount of coating is related to adhesive strength, it needs to be set in accordance with the selection of the above-mentioned materials and adjustment of the composition.
