【Example】

 The present invention will be described below with reference to the drawings. FIG. 1 is an example of a sectional view of the seat of the present invention. Reference numeral 1 is a writing layer having scratch resistance, stain resistance, and marker writing and erasing properties on the surface. The resin forming the writing layer 1 is a thermosetting resin or an ionizing radiation curing resin. Resin is used. The thermosetting resin is an organosilane resin, which is a hydrolyzate of aminosilane epoxy silane, a silane coupling agent, an alkylalkoxysilane, a partial hydrolyzate of tetraalkoxysilane, a colloidal silica, or a hydrolyzate of alkyltrioxysilane. Decomposition products, thermosetting silicone resins, and the like can be mentioned. These are diluted and applied to the backing material described later, and are left to stand naturally or cured by heating. Examples of the ionizing radiation-curable resin include unsaturated polyester, polyether acrylate, polyester acrylate, epoxy acrylate, urethane acrylate, spiroacetal acrylate, polybutadiene, and polythiolpolyene. These ionizing radiation curable resins may be used as a mixture of bifunctional or higher polyfunctional monomers for the purpose of improving the curing speed and the crosslinking density. As the polyfunctional monomer, for example, bifunctional monomers such as neopentyl glycol diacrylate, tripropylene diacrylate, diethylene glycol diacrylate, and 1,6-hexanediol diacrylate, trimethylolpropan triacrylate, pentaerythritol triacrylate, dipentaerythryl diacrylate. There are trifunctional monomers such as thylitol hexaacrylate, or 4, 5 and 6 polyfunctional monomers. A photopolymerization initiator and a sensitizer are added to the ionizing radiation curable resin when curing is performed with ultraviolet rays. Examples of the photopolymerization initiator include acetophenone type, bunzophenone, Michler's ketone, benzoin, benzylmethyl ketal, benzoyl benzoate, α-amyloxime ester, tetramethylthiuram monosulfide, and thioxanthone. There are n-butylamine, triethylamine, tri-n-butylphosphine and the like. The ionizing radiation curable resin is applied alone or as a mixture of the above-mentioned monomers, photopolymerization initiators and sensitizers as necessary, and is applied to the surface of the backing material described below, and then ionizing radiation such as ultraviolet rays or electron beams Irradiate and cure.

The curable resin as described above is, for example, a blade coating method, a flow coating method, a gravure coating method, a rod coating method, a knife coating method, a reverse roll coating method, a spray coating method, an offset gravure coating method, a kiss coating method. It is applied to the backing material described later by any application method, such as gravure coating method, reverse roll coating method, flow coating method, offset gravure coating, which is particularly excellent in accuracy of coating thickness and smoothness of coating surface. The method is preferred. Further, if the coating amount of the above-mentioned curable resin is too small, sufficient surface hardness, surface strength or scratch resistance cannot be obtained, and if it is too large, the curing rate decreases, etc., so that 1 to 100 μm, particularly 1 A thickness (dry thickness) in the range of about 40 μm is preferable. The writing layer 1 may be white opaque, colored opaque, colored transparent or uncolored transparent, or may be partially colored.

Reference numeral 2 is a backing material, and examples thereof include a plastic sheet, paper, cloth, particle board, wood board, and steel plate. If a stiff backing material is used, it can be used as it is, for example, as a whiteboard. If you use a soft backing material, you can use it as it is, but if you stack a magnet on the back side of the backing material, you can use the sheet of the present invention by pasting it on an iron board. Alternatively, the sheet of the present invention may be attached to a hard base material with an adhesive layer, with the writing layer as the outermost surface, to be used as a whiteboard. Also, some of the sheets of the present invention may be bound and used in a notebook form. Further, the backing material 2 may have a surface subjected to a primer treatment or a corona discharge treatment for the purpose of improving the adhesiveness of the surface thereof.

Reference numeral 3 is a pattern printing layer. As shown in FIG. 1, the pattern print layer 2 has a pattern formed by diffusing a pattern with a sublimation heat diffusing ink inside the writing layer 1, or a pattern printed on the outermost surface of the writing layer 1 by a normal printing method, or a writing pattern. There are things such as layering a pattern printing layer on the inside of Layer 1, but when the ink is raised on the outermost surface of the writing layer, the ink rises, so the pen tip is printed when writing with a water-based marker pen. The ink may get caught in the ink, and the printing ink may peel off during long-term use. In the case where the pattern printing layer is laminated inside the writing layer, it is desirable that the writing layer be transparent. When it is desired to hide the lower layer, a hiding layer is required. Therefore, as shown in FIG. 1, the pattern printing layer 2 is preferably one in which the pattern is diffused inside the writing layer 1 with a sublimation heat diffusing ink. By providing the pattern printing layer in this manner, a sheet having a smooth surface and a pen tip which is not caught even when writing on the pattern printing layer and has a good writable surface can be obtained. Such a pattern printing layer 3 is formed by a printing method using a known ink or a printing method using a sublimation heat diffusing ink.

FIG. 2, FIG. 3 and FIG. 4 show specific examples of the pattern of the pattern print layer such as the target pattern / character for writing. FIG. 2 is an example of a printed pattern of a sheet having a writable surface for practicing characters. 4 is a solid line character in which the practice character is displayed as a solid line, 5 is a stroke order display character in which the stroke order of the practice character is displayed (such as ...), and 6 is a written character in which the practice character is displayed as a white character. is there. The person practicing refers to the solid line character 4, confirms the stroke order with the stroke order display character 5, and correctly writes in the white part 61 of the written character 6 with a writing instrument such as a water-based marker pen. You can practice kana, katakana, romaji, kanji, alphabet, and so on. The writing character 6 may be displayed with a dotted line or with a thick line, and when it is displayed with a thick line, it is printed with a colored transparent ink or a light-colored ink in consideration of writing from above. Is preferred.

FIG. 3 shows an example of a printed pattern of a sheet having a writable surface for infants, which is used for both entertainment and learning. 7 is a coloring picture drawn in white, and those who use this will enjoy coloring the white area 71 with a colored water-based marker pen according to the color of the drawn picture 7. Furthermore, a writing section 8 for writing the name of the drawn picture may be provided so that the white area 81 can be written to the name of the picture. In addition to the vegetables and fruits shown in Fig. 3, it is also possible to use patterns such as animals, flowers, and vehicles that interest young children.

FIG. 4 is an example of a printed pattern of a sheet having a writable surface for learning, in this case for learning geography. To use this, the blank map 9 is viewed and the place name of the portion shown in the writing unit 10 or the names of mountains, rivers, plains, etc. are written. The sheet is not limited to the example of the sheet as described above, and the sheet for various purposes can be created by various combinations. Also, the pattern of the pattern print layer is not limited to the above example, and various kinds of music such as a staff of music and a game that can be written and played, for example, Go are conceivable.

An example of the method for producing the sheet shown in FIG. 1 is as follows. For example, a sublimation heat diffusing ink is used to prepare a transfer sheet on which a pattern is printed on a film, and a polyester resin is applied to the surface of a steel sheet. Then, it is cured to form a writing layer. The printing surface of the transfer sheet is superposed on the writing layer so that the sublimation heat diffusing ink is heated and pressed to vaporize the sublimation heat diffusing ink to diffuse the printing surface inside the writing layer.・ There are ways to make it penetrate. The structure of the sheet of the present invention is not limited to that shown in FIG. 1, and various structures such as providing a synthetic resin layer may be considered if necessary, and the pattern printing method is the sublimation transfer printing method described above. Alternatively, a method of directly printing on the writing layer is also possible.
