DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a transparent display material and a method of manufacturing a transparent display material, wherein the inside can be visually recognized from the inside, but the inside is hard to be viewed from the outside. And a method for producing a see-through display object using a material for producing a see-through display object.

[0002]

2. Description of the Related Art Heretofore, some films for window application have been required to have a performance in which the outside can be visually recognized from the inside while the inside cannot be visually recognized from the outside. To meet such demands, various films have been proposed (Japanese Utility Model Application Laid-Open No. 51-86049, Japanese Utility Model Application Laid-Open No.
68498). These are formed by printing an image on one side of the base material on one side and then punching this out partially to provide a large number of through-holes or printing halftone dots having a concealment property on a transparent base material. Then, an image is printed by superimposing on the halftone dot. That is, while the outside can be visually recognized from the inside through the through-hole or the non-image portion of the transparent base material, attention is drawn to the image formed on the outside surface, thereby making it difficult to visually recognize the inside from the outside. It is effective.

[0003]

However, in these methods, holes are formed after an image or the like is formed by printing. Therefore, a machine for forming fine holes at uniform intervals is required to produce the holes. Therefore, it has been practically difficult to produce an original transparent display material at an individual level because of the necessity of a plate making process for printing.

[0004]

The inventor of the present invention has made intensive studies to solve the above-mentioned problems, and as a result, has accomplished the present invention.

[0005] That is, the material for producing a transparent display according to the present invention is characterized in that a substrate having a large number of through holes is releasably attached to a transparent substrate.

[0006] Alternatively, a layer having a concealing property and an ink receiving property is provided on a surface of a base material side having a large number of through-holes of the material for producing a transparent display object. is there.

Further, according to the method of the present invention for producing a see-through display material, the method comprises the steps of: attaching a base material having a large number of through holes to a transparent base material in a releasable manner; A layer having a hiding property and an ink receiving property is formed by spraying a coating material on the surface on the side of the substrate having the above.

Further, according to the method for producing a see-through display object of the present invention, a substrate having a large number of through holes is releasably attached to a transparent substrate, and the substrate having the large number of through holes is provided. By spraying a paint on the side surface, a layer having a concealing property and an ink receiving property is formed, and after outputting an image on the surface by an inkjet printer, the base material having the large number of through holes and the transparent material Characterized in that it is separated from the conductive substrate.

Alternatively, a base material having a large number of through holes is releasably attached to a transparent base material, and a paint is sprayed on the surface of the base material side having the large number of through holes to form an ink. Forming a transparent resin layer having receptivity, outputting an image on the surface by an inkjet printer, further forming a layer having concealing properties and ink receptivity on the surface, and forming an image on the surface by an inkjet printer. After the output, the base material having the large number of through holes and the transparent base material are separated.

[0010] According to such a material for making a transparent display, the through-hole is formed in advance, so that the purchaser does not need a drilling machine and can easily form an image or the like by an ink jet printer. Therefore, a plate making process is not required, and a transparent display material including an original image can be easily produced. In addition, different types of transparent display objects such as a transparent type based on a transparent base material and a perforated type based on a base material having a large number of through holes can be obtained at the same time.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a material 4 for a transparent display object of the present invention will be described.

[0012] The material 4 for making a transparent display object of the present invention.
Is characterized in that a substrate 2 having a large number of through holes is releasably attached on a transparent substrate 1 (FIG. 1).

The material of the transparent substrate 1 is not particularly limited as long as it has such a transparency that the opposite side can be seen through when it is attached to the window glass 6. Plastic films such as polyethylene, polypropylene, and polystyrene are preferably used.

The transparent substrate 1 preferably has an adhesive layer 12 on a surface opposite to a surface to be adhered to a substrate 2 having a large number of through holes described later (see FIG. 1). ). When the adhesive layer 12 is provided, it is not necessary to separately apply an adhesive when sticking to the window glass 6 as a transparent display object, so that workability can be improved (FIG. 5, FIG. 5). 6). As the adhesive constituting the adhesive layer 12, a conventionally known adhesive can be used. It is preferable that a release film 13 be provided on the adhesive layer 12 in consideration of transportation to an inkjet printer.

The substrate 2 having a large number of through-holes is releasably adhered to the transparent substrate 1 and is not particularly required to have transparency. It can be obtained by providing a large number of through holes in a material by a punch press or the like. The shape and distribution of the through holes 22 differ depending on which type of transparent display object is to be obtained. That is, when a transparent type (see FIGS. 5, 6, and 8) based on the transparent substrate 1 is used,
It is preferable that a large number of relatively large diameter holes be distributed and the area occupied by the through holes 22 in the base material 2 be 60% or more. On the other hand, when using a perforated type (FIGS. 7 and 9) based on the base material 2 having a large number of through holes, a large number of relatively small holes are distributed, and the through holes 2 in the base material 2 are formed.
The area occupied by 2 is preferably less than 40%. In this way, it is possible to make it difficult to visually recognize the inside from the outside and to easily view the outside from the inside without damaging the image 5 of the see-through display object of the type actually used. When both types of transparent display objects are used, from the same viewpoint, a large number of medium-sized holes are distributed, and the area occupied by the through-holes 22 in the base material 2 is 40 to 6.
It is preferably set to 0%.

It is preferable that the substrate 2 having a large number of through holes has an adhesive layer 23 having holes corresponding to the through holes 22 (see FIGS. 1 to 4). By having such an adhesive layer 23, the work of sticking to the transparent substrate 1 described above becomes easy (FIGS. 1 to 4).
When sticking to the window glass 6 as a see-through display, there is no need to separately apply an adhesive, and the workability can be improved (see FIG. 7). Such an adhesive layer 2
3 can be obtained by forming an adhesive layer 23 on the base material 2 and then forming a large number of through holes 22 by a punch press or the like.

As the adhesive constituting the adhesive layer 23, a conventionally known adhesive can be used. In addition, the through hole 2
It is preferable to provide a release film 24 on the adhesive layer 23 in order to improve the operability when forming No. 2 (FIG. 10).

The means for releasably attaching the substrate 2 having a large number of through holes to the transparent substrate 1 includes a method using an adhesive or a tape, and a substrate 2 having a large number of through holes. When the adhesive layer 23 is provided, a method utilizing the adhesiveness of the adhesive layer 23 may be used. When using an adhesive, the adhesive force of the adhesive to be used is adjusted, or the adhesive is reduced by partially contacting the adhesive with the adherend (for example, the adhesive is formed into a matrix). The peel force is adjusted by the formed matrix adhesive layer). Since the two substrates are adhered in this way, the positions of the two substrates do not shift during recording by the ink jet printer, and the resulting image 5 of the see-through display object does not become uneven.

According to the see-through display material producing material 4 having such a configuration, the purchaser conceals the paint by spraying the paint on the surface of the base material 2 having a large number of through holes. After forming a layer having the properties and the ink receptivity (FIGS. 2 and 3) and outputting an image 5 on the surface by an ink jet printer, the substrate 2 having a large number of through holes and the transparent substrate 1
Is peeled off, a transparent display object can be obtained (see FIGS. 5 to 9).

The layer to be formed here can be made as shown in FIG. 2 as long as it imparts the concealing property and the ink receiving property to the surface on the side of the base material 2 having a large number of through holes of the material 4 for the transparent display object.
As shown in FIG. 3, a single layer having both the concealing property and the ink receiving property as shown in FIG. And three or more layers.

The formation of these layers is carried out by spraying a paint.
Examples include a spray method, an airbrush method, and spraying from an inkjet printer head.

The paint used depends on which layer is to be formed. That is, as shown in FIG. 2, if it is a single-layer type, it becomes a paint capable of simultaneously providing opacity and ink receptivity, and if it is a two-layer type, as shown in FIG. And a paint that imparts ink receptivity.

The paint for imparting hiding power is mainly composed of a binder resin and a colorant. Examples of the binder resin include vinyl acetate, polyurethane, polyester, and alkyd resins. As the coloring agent, a dye, an organic pigment, an inorganic pigment, or the like can be used. For example, when the concealing layer 32 is made white, titanium oxide and barium sulfate can be used, and when it is made black, carbon black and the like can be used.

The coating material for imparting ink receptivity may be one used for the ink receiving layer of a conventionally known ink jet recording material, and is mainly composed of a water-soluble resin. It may be a mixture of a polymer compound such as a resin or a water-insoluble resin, an extender, an additive such as an ultraviolet absorber and a leveling agent.

Examples of the water-soluble resin include synthetic resins such as polyvinyl alcohol, polyvinylpyrrolidone, hydroxycellulose, acrylic acid and acrylate, and natural resins such as gelatin, casein, starch, chitin and chitosan. As water-resistant water-soluble resin,
Those obtained by reacting with a water-soluble resin through an ionic bond, a coordinate bond, a covalent bond, a hydrogen bond, or the like. As the water-insoluble resin, styrene maleic acid copolymer, vinyl chloride vinyl acetate copolymer, acrylic resin, cellulose resin,
And polyvinyl acetal.

Incidentally, the paint for imparting ink receptivity may contain a hot melt resin, a thermoplastic resin, a crystalline plasticizer, a tackifier, and the like. By appropriately including a hot melt resin or the like, if this is heated, the surface of the layer having the ink receptivity can be attached to the window glass 6, and after applying an adhesive as a post-treatment, The work efficiency can be improved as compared with sticking to the window glass 6 (FIGS. 8 and 9). Also, image 5
Is protected between the window glass 6 and the plastic film, so that there is no need to provide a separate protective film or the like.

In order for the layer having ink receptivity to exhibit adhesiveness, “a hot melt resin only”, “hot melt resin and tackifier”, “thermoplastic resin and crystal” The method of adding a "plasticizer" or a "thermoplastic resin, a crystalline plasticizer and a tackifier" may be mentioned. In any case, the total content of the added resin is 100 to 10 with respect to the water-soluble resin.
It is preferably in the range of 00% by weight. 100% by weight
With the above, sufficient adhesiveness can be obtained, and when the content is 1000% by weight or less, the ink receiving performance is not hindered. Such hot melt resins, thermoplastic resins, crystalline plasticizers,
Conventionally known tackifiers can be used.

The coating material having a hiding property and an ink receiving property includes:
It is mainly composed of a water-soluble resin and a coloring agent. The same water-soluble resin and colorant as those exemplified above can be used.

Further, the material 4 for producing a transparent display object of the present invention comprises a plurality of through-holes of a laminate obtained by releasably attaching a base material 2 having a large number of through holes and a transparent base material 1. A layer having a hiding property and an ink receiving property may be formed in advance on the surface of the substrate 2 having the holes (FIGS. 2 and 3).

As means for forming a layer having a hiding property and an ink receiving property in advance, in addition to the method of spraying the above-mentioned coating material, a coating solution prepared by dissolving or dispersing the above-mentioned resin or coloring agent in a solvent. Is applied and dried by a known coating method such as bar coating.

The see-through display material is such that the above-described see-through display material production material 4 does not have a layer having a hiding property and an ink receiving property in advance (FIG. 1). After forming a layer having a concealing property and an ink receiving property by spraying a coating material on the surface of the structuring material on the side of the base material 2 having a large number of through-holes, the structuring material 4 of a see-through display object has the In the case of having a layer having ink receptivity (FIGS. 2 and 3), the image 5 is output as it is by the inkjet printer, and then the transparent substrate 1 and the substrate 2 having a large number of through holes are separated. It can be obtained by peeling (FIGS. 5 to 9).

In the case where the transparent display material thus obtained has an adhesive layer, as shown in FIGS. 5 to 7, a hot melt resin or a thermoplastic resin and In the case of containing a crystalline plasticizer, it is used by sticking to the window glass 6 as shown in FIGS. In the case where the see-through display object itself does not have the above-described adhesive performance, an adhesive is separately applied to the surface on which the image 5 is formed or the surface opposite to the surface on which the image 5 is formed. Is attached to the window glass 6. The see-through display material attached to the window glass 6 can be viewed from the inside to the outside through the through-hole 22 or the non-image portion of the transparent base material 1 due to the presence of the through-hole 22, while the person outside is not visible. Attention is paid to the image 5 directed to the outside, and the effect of making it difficult to visually recognize the inside is exerted.
