DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be further described below with reference to embodiments shown in the drawings. FIG. 1 is a view showing one embodiment of a facsimile sheet of the present invention. The facsimile sheet is formed on a base material 10 having an image layer 11 formed of predetermined characters and symbols on its surface and formed on the image layer. A writing sheet 1 having a written / erasable writing layer 12,
A transparent cover film 2 fixed to one end of the writing sheet and covering the writing layer.

The image layer 11 of the writing sheet 1 is formed by printing on a substrate 10 such as paper or a synthetic resin film, exposing and developing, electrostatic transfer recording, ink jet recording, and thermal transfer recording. It is formed by one of the image forming methods. Preferably as the substrate 10,
A material (hereinafter, referred to as an image forming material) capable of forming an image by any one of an image forming method selected from an exposure / developing method, an electrostatic transfer recording method, an ink jet recording method, and a thermal transfer recording method is used. A predetermined image layer 11 is formed on such a material by the above-described image forming method. The use of such an image forming material to form the image layer 11 eliminates the need for a plate-making process in the case of printing, so that the work time and the manufacturing cost can be reduced, and a facsimile sheet suitable for a small number of products. Can be provided. The user can provide an arbitrary image layer by using an image forming material and a later-described laminate type as a writing layer.

As the image forming material for forming an image by a development process, a layer capable of dyeing or exposing the exposed portion or the other portion on the support film by exposure / development process, or a layer exposed to color by the development process. A photosensitive film having a layer in which a portion or other portions dissolve or swell and peel off may be used.

As a material for forming an image by electrostatic transfer recording such as a PPC, a laser printer or an electrostatic plotter, a toner containing a resin having a good adhesive property such as a polyester resin or an acrylic resin on a support film is used. An electrostatic transfer film having an easily adhesive layer is used. When an image is formed by ink jet recording using an ink jet printer or the like, a film having an ink receiving layer containing an aqueous ink such as polyvinyl alcohol or a hydrophilic acrylic resin as an image forming layer is used. When using thermal transfer recording,
A film is used in which an ink receiving layer having an acceptability for the thermal transfer ink is used as an image forming layer.

The support film of such an image forming material is not particularly limited as long as it is a material suitable for an image forming method and has facsimile suitability, and paper, a synthetic resin film and the like are used. As a synthetic resin film,
Polyester, polyethylene, polyvinyl chloride, polyvinylidene chloride, polycarbonate, polystyrene, polyacrylonitrile, ABS, nylon, polypropylene and the like are used. The thickness of the support film is not particularly limited, but is 25 to 188 μm from the viewpoint of requiring flexibility.
Use the ones in the range.

The writing layer 12 is formed by coating a composition containing a thermosetting resin or a photocurable resin on the image layer of the substrate 10 on which the image layer 11 is formed, and then curing the composition. It is formed by laminating a material having a crosslinked cured film formed by curing a composition containing a mold resin or a photocurable resin.

When the writing layer 12 is formed by coating, the resin constituting the writing layer 12 can be either a thermosetting resin or a photocurable resin from the viewpoint of surface hardness, but it is difficult to work. For this reason, it is preferable to use a photocurable resin, particularly an ultraviolet or ionizing radiation curable resin. When formed by lamination, as shown in FIG. 2, a crosslinked cured film 2 containing a thermosetting resin or a photocurable resin (ultraviolet or ionizing radiation curable resin) on a transparent plastic film 21 such as a polyester film.
The material forming 2 is laminated via the pressure-sensitive adhesive layer 23.

The method of forming the writing layer 12 by laminating through the pressure-sensitive adhesive layer 23 is advantageous in that flexibility can be imparted to the entire sheet and that the user can easily form the image layer after forming an arbitrary image layer. This is preferable in that a writing layer can be formed.

The crosslinked cured film 22 is obtained by introducing a crosslinked structure by irradiating ionizing radiation to a coating film of a composition mainly composed of a thermosetting resin or a photocurable resin, preferably an ultraviolet or ionizing radiation curable resin. is there.

As the ionizing radiation-curable resin, those having an acrylic group such as unsaturated polyester, polyether acrylate, polyester acrylate, epoxy acrylate, urethane acrylate, spiroacetal acrylate, polybutadiene resin, polythiol polyene resin and the like can be used. it can.

The above-mentioned ionizing radiation-curable resin can be used alone, but it is preferable to add a polyfunctional monomer in order to improve the curability and the hardness of the cured coating film. Trimethylolpropane triacrylate, pentaerythritol triacrylate Or a trifunctional monomer such as dipentaerythritol hexaacrylate, a bifunctional monomer such as neopentyl glycol diacrylate, tripropylene glycol diacrylate, diethylene glycol diacrylate, or 1,6-hexanediol diacrylate, or a tetrafunctional monomer or a pentafunctional Alternatively, it can be appropriately selected from monomers having six functionalities and used.

In addition, various additives may be added to the ionizing radiation-curable resin. When ultraviolet rays are used for curing, a photoinitiator such as acetophenones, benzophenone, Michler's ketone, benzoin, benzyl methyl ketal is used. , Benzoyl benzoate, α-acyloxime ester, thioxanthone, or the like, or n-butylamine, triethylamine, tri-n-butylphosphine, or the like as an ultraviolet sensitizer.

The composition mainly composed of an ionizing radiation-curable resin may contain a matting agent in order to adjust the gloss of the cured coating film. As the matting agent, inorganic particles such as silica, calcium carbonate, and precipitated barium carbonate, or organic particles such as fluorine particles, polyethylene particles, and acrylic particles can be used. However, the amount of the additive must be such that the lower image layer can be seen through, specifically, the amount that the total light transmittance becomes 80% or more.

Compositions based on ionizing radiation-curable resins can be prepared by conventional coating methods such as Meyer bar coating, blade coating, gravure coating, rod coating, knife coating, reverse roll coating, kiss coating, spray coating, or offset. On the surface of the transparent plastic film 21 constituting the writing layer 12 by a method such as gravure coating or directly on the surface of the image layer 11,
Apply. After coating, the coating film is irradiated with ionizing radiation using ultraviolet light or an electron beam to crosslink and cure the coating film. For electron beam, Cockloft-Walton type, Bande graph type, Resonant transformer type, Insulated core transformer type, Linear type,
Emitted from various electron beam accelerators such as a dynamitron type and a high frequency type, and 50 to 1000 keV, preferably 100 to 1000 keV.
An electron beam having an energy in the range of 300 keV is used, and ultraviolet rays emitted from an ultraviolet source using a light source such as an ultra-high pressure mercury lamp, a high pressure mercury lamp, a low pressure mercury lamp, a carbon arc, a xenon arc, and a metal halide lamp are used. The introduction of the crosslinked structure in this manner improves the erasability and abrasion resistance of the written contents while maintaining flexibility.

In the case of ultraviolet curing, irradiation with an inert gas or lamination of a film is performed to cut off oxygen in order to promote the curing reaction. In the case of electron beam curing, these means are usually employed. Curing proceeds without it. However, when the surface properties of the coating film are required as in the present invention, the inert gas is also used for electron beam curing,
It is more effective to use the film as described above.

The transparent cover film 2 prevents characters and the like written on the writing layer 12 from being erased by contacting the facsimile roller or soiling the roller. The transparent cover film 2 can read characters and the like on the image layer by facsimile. It is made of a material having properties. Examples of such a material include synthetic resin films such as polyester, polyethylene, polyvinyl chloride, polyvinylidene chloride, polycarbonate, polystyrene, polyacrylonitrile, ABS, nylon, and polypropylene.

The transparent cover film 2 is preferably provided with a hard coat layer on the outer surface. The hard coat layer can be composed of the same thermosetting resin or light curable resin as the resin constituting the writing layer 12, and a paint containing such a resin is coated on the surface of the synthetic resin film constituting the transparent cover film 2. , And then cured. The thickness of the hard coat layer is 1 to 5 as long as the flexibility of the cover film is not impaired.
About μm is preferable. By providing such a hard coat layer, it is possible to prevent the surface of the cover film from being damaged by repeated use, and to prevent the transparency from being damaged by the damage.

Such a transparent cover film 2 is shown in FIG.
As shown in (a) and (b), the above-described writing sheet 1 is adhered to one end of the writing layer 12 or the back side of the image layer 11 via the adhesive 3. When the transparent cover film 2 is attached to the image layer 11 side, it is preferable that the portion is previously bent. The adhesive 3 is not particularly limited as long as it can bond the resin constituting the writing layer 12 or the support film of the image layer and the material constituting the transparent cover film 11.

A transparent cover film 2 is prepared by applying an adhesive 3 at a predetermined width to one end of a synthetic resin film in advance, and a user forms a writing sheet 1 on which an image layer 11 of a predetermined format is formed. After that, it may be attached to the back side of the writing sheet 1 or the image layer 11.

The method for fixing the transparent cover film 2 to the writing sheet 1 is not limited to the method using an adhesive as described above. For example, when the writing layer 12 is formed on the writing sheet 1 as shown in FIG. 1C, the writing layer 12 is applied with a predetermined width left at one end so that the support film 10 of the image forming material partially appears on the surface. Then, the transparent cover film 12 may be overlaid on the writing layer, and the support film portion and the transparent cover film may be fixed at one end by heat fusion. Further, as a support film of the image forming material for forming the writing sheet 1, a transparent support film having a size twice as large as the image layer is prepared, and an image layer 11 and a writing layer 12 are sequentially formed on half of the transparent support film. Alternatively, the remaining support film can be folded back to the writing layer side to form a transparent cover film (FIG. 4D).

Further, the facsimile sheet of the present invention includes:
In order to prevent the charging of the sheet when it is transferred, it is preferable to perform an antistatic treatment on the base material 10 and / or the transparent cover film 2. The antistatic treatment can be achieved by various methods, for example, by coating with an antistatic agent or kneading into a substrate or a cover film. As the antistatic agent, various surfactants such as cationic, anionic, nonionic and amphoteric, inorganic substances such as metal powder, carbon powder and graphite, or siloxane-based coating agents can be used.

The facsimile sheet of the present invention is formed, for example, by forming a desired format or the like (image layer) on an image forming material by a predetermined image forming method, and then forming a writing layer material as shown in FIG. (Transparent plastic film 21 having a cross-linked cured film 22 on the front surface and a pressure-sensitive adhesive layer 23 on the back surface) is laminated so that the surfaces of the pressure-sensitive adhesive layers 23 are opposed to each other to form a writing sheet 1, and then one end of the adhesive sheet The transparent cover film coated with is coated on the writing layer of the writing sheet 1 and adhered thereto.

According to such a method, a user can easily create a facsimile sheet having a desired format.

In use, with the transparent cover film 2 folded outward, the necessary items are written on the writing layer 12 with an aqueous pen (marker pen for whiteboard), and the transparent cover film 2 is overlaid on the writing layer 12. Through the facsimile feed mechanism. At this time, since the written matter is protected by the transparent cover film, it does not adhere to a roller or the like. Further, since the antistatic treatment is performed, troubles such as a jam at the time of feeding can be prevented. After use, it can be used repeatedly by deleting what is written on the writing layer.
