Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material for making a see-through display object that allows the outside to be visually recognized from the inside while it is difficult to see the inside from the outside. It relates to a manufacturing method.

[0002]

2. Description of the Related Art Heretofore, some films for window application have been required to have such a performance that it is possible to visually recognize the outside from the inside, but it is difficult to visually recognize the inside 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. 1-68).
498). In these, a reflective paint is applied to one surface of a base material or an image is formed, and then this is partially punched out to provide a large number of through holes. That is, while the outside can be visually recognized from the inside (the side that prevents visual recognition) through the through-hole, attention is drawn to the reflection of light by the reflective paint or the image formed on the outside surface. Thereby, an effect of making it difficult to visually recognize the inside from the outside is exerted.

[0003]

However, in these methods, holes are formed after an image is formed by an ink-jet printer or the like. Therefore, a machine for forming fine holes at uniform intervals is required for producing the holes. It became necessary and it was practically difficult to produce original, translucent displays at the individual level.

[0004]

In order to solve this problem, it is conceivable to previously provide a large number of through-holes in an ink-jet recording material having concealing properties. In this case, there is a problem that the inside of the printer is stained by ink leaked from the through holes.

[0005] The inventors of the present invention have made intensive studies to solve the above-mentioned problems, and as a result, have come to solve them.

That is, the material for forming a see-through display material of the present invention has a plurality of through-holes, and a portion other than the through-holes has a concealing property and an ink-jet printing characteristic. And an absorbing member.

[0007] Preferably, the transparent recording material is:
It has an adhesive layer having a hole corresponding to the through hole.

Alternatively, the transparent recording material has a structure in which a large number of through holes are provided in a concealable ink jet recording material having an ink receiving layer. It is characterized by containing a hot melt resin.

Alternatively, the transparent recording material has a structure in which a large number of through-holes are provided in an ink-jet recording material having an ink receiving layer and having a concealing property. It is characterized by containing a thermoplastic resin and a crystalline plasticizer.

[0010] Alternatively, the ink absorbing member has a structure in which an ink absorbing layer having adhesiveness is provided on a support.

Alternatively, the ink-absorbing member has a linear or lattice-shaped adhesive layer having a line width smaller than the diameter of the through-hole of the transparent recording material on a base material having an ink-absorbing property. It is characterized by becoming.

Alternatively, the ink-absorbing member has an adhesive layer on a base material having an ink-absorbing property, on which a number of figures having a diameter smaller than the diameter of the through-hole of the transparent recording material are arranged. It is characterized by the following.

[0013] Alternatively, the transparent recording material and the ink absorbing member are releasably attached to each other.

Further, according to the method for producing a see-through display material of the present invention, an ink-jet recording of a see-through recording material having a large number of through-holes and a portion other than the through-holes has concealing properties and ink-jet recording characteristics. An ink absorbing member is laminated on a surface opposite to a possible surface, an image is output by an ink jet printer on an ink jet recordable surface, and then the ink absorbing member is removed.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, a material 3 for a transparent display object of the present invention will be described.

[0016] Material 3 for making a transparent display object of the present invention
Is characterized by having a large number of through-holes 14 and a portion other than the through-holes 14 being composed of a transparent recording material 1 having concealing properties and ink jet recording characteristics, and an ink absorbing member 2. (See FIGS. 1 to 5).
Hereinafter, embodiments of each component will be described.

The transparent recording material 1 has a large number of through holes 1.
4, and the portion other than the through-hole 14 has concealing properties and ink jet recording characteristics. After recording an image with an ink jet printer, it is adhered to a transparent body such as the window glass 4, and the inner side to the outer side. While it can be visually recognized, it has an effect of making it difficult to visually recognize the inside from the outside. That is, the presence of the large number of through-holes 14 allows the inside to be seen through the outside, while the person on the outside is deprived of attention by the image directed to the outside, making it difficult to see inside. (FIGS. 9 to 11).

Such a transparent recording material 1 can be obtained by providing a large number of through-holes 14 in an ink-jet recording material having a concealing property by a punch press or the like.

The ink-jet recording material having a concealing property can be obtained by forming an ink receiving layer 12 on a base material 11 having a concealing property. of course,
An ink receiving layer having a hiding property may be formed on a substrate having no hiding property.

As the base material 11 having a hiding property, a white pigment or a black pigment is kneaded into a non-hiding material such as polyester, polycarbonate, polyvinyl chloride, polyethylene, polypropylene, or polystyrene. And an opaque layer formed by applying a black paint or depositing a metal thin film on the substrate having no concealment property. Synthetic paper, paper, fiber cloth, etc. may be used as long as they have concealing properties. Although the thickness of these substrates is not particularly limited, it is desirable to use those having a thickness of preferably 5 to 300 μm from the viewpoint of transportability to a machine.

The base material 11 having a concealing property has a white surface on which the ink receiving layer 12 is formed, and has a low surface reflectance on the surface opposite to the surface on which the ink receiving layer 12 is formed. Preferably, there is. If the surface on which the ink receiving layer 12 is formed is white, it is possible to make the image formed on the ink receiving layer 12 less susceptible to the influence of the substrate, and the surface opposite to the surface on which the ink receiving layer 12 is formed. If it is black or the like having a small surface reflectance, it is possible to make it easy to visually recognize the inside from the outside. Such a thing can be obtained by providing a black layer on one surface of a white opaque film, or providing a white layer on one surface of a black opaque film.

Further, if an image is previously provided on the surface of the substrate 11 having the concealing property opposite to the surface on which the ink receiving layer 12 is formed, a through hole 14 is provided in the substrate, and the ink receiving layer 12 is provided. After recording the image, different images can be observed on the front and back.

The ink receiving layer 12 may be any ink receiving layer used in conventionally known ink jet recording materials, and is mainly composed of a binder resin, an inorganic pigment, resin beads, and the like.

The binder resin is mainly composed of a water-soluble resin, but may be a mixture of a water-resistant water-soluble resin or a water-insoluble resin as required. As the water-soluble resin, polyvinyl alcohol,
Examples include synthetic resins such as polyvinylpyrrolidone, and natural resins such as gelatin, starch, chitin, and chitosan.
Examples of the water-resistant resin which has been made water-resistant include those which have been insoluble by reacting with the water-soluble resin through an ionic bond, a coordination bond, a covalent bond, a hydrogen bond, or the like. Examples of the water-insoluble resin include styrene-maleic acid copolymer, vinyl chloride-vinyl acetate copolymer, acrylic resin, polyvinyl acetal and the like.

As inorganic pigments, silica, clay, calcium carbonate, calcium sulfate, barium sulfate, titanium oxide, zinc oxide, alumina, smectite, etc., and as resin beads, polymethyl methacrylate, polystyrene, polyurethane, benzoguanamine, silicone resin And hollow resin beads using these as a raw material. These inorganic pigments and resin beads have a role of assisting ink absorption and preventing blocking of the ink receiving layer. When the ink receiving layer has a hiding property, a white pigment such as titanium oxide or barium sulfate is added to the binder resin for 200 hours.
It is preferred that the content be contained by weight% or more.

The ink receiving layer 12 may contain a hot melt resin, a thermoplastic resin, a crystalline plasticizer, a tackifier, and the like. When an image is formed on the transparent recording material 1 by heating and then heating, the surface on the ink receiving layer 12 side can be adhered to the window glass 4 by appropriately including a hot melt resin or the like. (FIG. 10), the work efficiency can be improved as compared with the case where an adhesive is applied as a post-processing and then the window glass 4 is adhered. Further, the image is protected by being sandwiched between the window glass 4 and the base material 11 having the concealing property, so that it is not necessary to separately provide a protective film or the like.

In order for the ink receiving layer 12 to exhibit adhesiveness, "hot melt resin only", "hot melt resin and tackifier", "thermoplastic resin and crystalline plasticizer" are contained in the ink receiving layer 12. Alternatively, a method of adding a “thermoplastic resin, a crystalline plasticizer and a tackifier” may be mentioned. In any case, the total content of the added resin and the like is in the range of 100 to 1000% by weight based on the water-soluble resin. It is preferred that When the content is 100% by weight or more, sufficient adhesiveness can be obtained, and when the content is 1000% by weight or less, the ink receiving performance is not hindered.

The hot melt resin is a heat-melt type adhesive made of a thermoplastic material which is applied as a fluid by heating and melting, and solidifies by cooling to exhibit an adhesive force. The hot-melt resin is an ethylene vinyl acetate-based, polyolefin-based, or polyamide-based adhesive. , Polyester, cellulose, and reactive hot melt. In addition, a water-soluble hot-melt resin made of a water-soluble thermoplastic resin such as a vinyl-based resin or a high-molecular-weight saturated polyester resin can form the ink-receiving layer 12 using the water-soluble hot-melt resin alone.

The thermoplastic resin is a source of adhesive strength, and examples thereof include vinyl acetate resins, acrylic resins, styrene resins, and polyesters. Further, among the thermoplastic resins, hydrophilic resins and the like are particularly preferable in terms of ink receptivity. Specifically, sulfone group-modified polyvinyl alcohol, acetoacetyl group-modified polyvinyl alcohol,
Examples include crosslinked polyethylene oxide, ethylene vinyl alcohol, and water-soluble polyester.

The crystalline plasticizer is a solid at room temperature, and therefore does not impart plasticity to the resin, and melts by heating to swell or soften the resin. At room temperature, the non-adhesive ink-receiving layer 12 is heated. It acts to develop adhesiveness. Usually, since the adhesive strength is maintained for several days, there is an advantage that the bonding operation can be easily performed without using a machine such as a heat laminator unlike a general heat-melt type adhesive.

The crystalline plasticizer has a melting point of 50 to 100.
C. is preferable. If the melting point is too close to room temperature, blocking tends to occur, and if it is too high, the heating operation becomes inconvenient. The main crystalline plasticizers include diphenyl phthalate, dicyclohexyl phthalate, dihexyl phthalate, dimethyl isophthalate, sucrose benzoate and the like. The amount of the crystalline plasticizer to be added is preferably from 30 to 300% by weight, more preferably from 50 to 150% by weight, based on the thermoplastic resin. 30-30
If the content is 0% by weight, the effect of exhibiting adhesiveness is extremely large.

Tackifiers improve initial or residual adhesion. Examples of the tackifier include rosin resins and derivatives thereof, butyral resins, acrylonitrile polymers, aliphatic petroleum resins, and aromatic petroleum resins.

A punch press or the like is used to provide the through-holes 14 in the transparent recording material 1. Although the shape and distribution of the through-holes 14 are arbitrary, it is preferable to increase the number of small-diameter holes because they do not impair the image, make it difficult to see from inside to outside, and make it easy to see from inside to outside.

In the present invention, the transparent recording material 1 preferably has an adhesive layer 13 having holes corresponding to the through holes 14 (see FIGS. 3 and 5). If such an adhesive layer 13 is provided, even when the ink receiving layer 12 does not exhibit adhesiveness,
When sticking to the window glass 4 as a transparent display after inkjet recording, it is not necessary to separately apply an adhesive, and the workability can be improved (FIGS. 9 and 1).
1). Further, when the ink-absorbing member 2 and the ink-absorbing member 2 to be described later are laminated, the two members are temporarily adhered to each other, so that misalignment of the two members at the time of recording with an ink jet printer can be prevented, and image unevenness can be prevented. The recording material 1 which can be seen through may be made to exhibit concealing properties by adding a black pigment to the adhesive layer 13 (see FIG. 5).

Adhesive layer 13 having holes corresponding to through holes 14
After forming the adhesive layer 13 on the surface of the ink-jet recording material having concealing properties opposite to the surface on which ink-jet recording is possible, a plurality of through holes 14 are formed by punch press or the like. Can be obtained by:

Examples of the adhesive forming the adhesive layer 13 include an adhesive having an adhesive property at normal temperature, a hot-melt adhesive which is non-adhesive at normal temperature but develops adhesive property by heating at the time of application. And various adhesives.

As these adhesives, natural rubber-based, recycled rubber-based, chloroprene rubber-based, nitrile rubber-based, styrene-butadiene-based elastomer adhesives, epoxy-based, urethane-based, acrylic-based, cyanoacrylate-based, etc. Resin adhesive, other UV curable adhesive, EB
Curable adhesives, emulsion adhesives and the like can be mentioned.

The adhesive layer 13 does not necessarily have to be provided on the entire surface of the substrate 11, but may be provided on at least a part of the substrate 11. This is because it is not always necessary to stick the entire surface when sticking to the window glass 4 or the like.

Further, the release film 1 is provided on the adhesive layer 13.
5 is preferably provided. By providing the release film 15, workability in forming the through holes 14 and the like can be improved (FIG. 12).

The ink absorbing member 2 has a role of absorbing the ink leaked from the through-hole 14 of the transparent recording material 1 so as not to stain the inside of the ink jet printer. Here, if the transparent recording material 1 is simply lined with a plastic film, the rear surface of the transparent recording material 1 is stained with undried ink.
By using the ink absorbing member 2, such inconvenience can be prevented.

As the ink absorbing member 2, not only a substrate itself such as a paper or a fiber cloth having an ink absorbing property but also an ink absorbing property, and a layer having an ink absorbing property on a support 21 such as a plastic film. It may be a film like an ink jet recording film on which 22 is formed (see FIGS. 3 and 5). When the ink absorbing layer 23 having an adhesive property is formed on the support 21, the two members are temporarily adhered to each other when they are laminated with the above-described transparent recording material 1, so that the two members can be used for recording with an inkjet printer. It is also possible to prevent the displacement of the members and to prevent image unevenness (FIG. 4).
reference).

As means for imparting adhesiveness to the ink absorbing layer, a method in which the main component of the ink absorbing layer is a polymer having both hydrophilicity and adhesiveness, or a method in which an adhesive polymer and a pigment are mixed. This is achieved by a method such as a method, a method of mixing an adhesive polymer and a hydrophilic polymer, or a combination thereof.

The ink absorbing member 2 is formed on a base material having an ink absorbing property, such as the above-mentioned paper, fiber cloth, or ink jet recording film, with a line width smaller than the diameter of the through hole 14 of the transparent recording material 1. A linear or lattice-shaped adhesive layer 24 or an adhesive layer 24 on which a number of figures having a diameter smaller than the diameter of the through hole 14 are arranged may be provided (see FIGS. 6 and 7). According to such an adhesive layer 24, not only can the ink absorbing member 2 and the transparent recording material 1 be temporarily bonded, but also the adhesive covers all the individual through-holes 14 of the transparent recording material 1. Since there is no ink, there is room for ink to be absorbed by the ink absorbing member 2, and even if an adhesive having no ink absorbing property is used, the back surface of the recording material 1 that can be seen during recording will not be stained (FIG. 5). According to the ink absorbing member 2 having such an adhesive layer 24, the ink absorbing adhesive layer 23 described above is used.
The same effect can be obtained without using a hydrophilic polymer or a pigment. Therefore, problems that occur when a hydrophilic polymer is used, for example, transfer of an adhesive to a transparent recording material 1, polymer Dissolution and swelling of the recording material 1 that can be seen through can be prevented from being stained.

It is to be noted that the above-described effect can be obtained even when an adhesive layer is formed on a portion of the ink absorbing base material other than the portion corresponding to the through hole 14 of the transparent recording material 1. Although it is possible, in this case, it is necessary to perform positioning when bonding the transparent recording material 1 and the ink absorbing member 2, and thus the workability is deteriorated. On the other hand, according to the shape of the adhesive layer 24 exemplified above, the above-mentioned effect can be obtained without any alignment.

As the adhesive used here, not only those having ink absorbency as described above, but also those having no ink absorbency can be used. The same adhesive as that exemplified above as the adhesive constituting the adhesive layer 13 of the recording material can be used.

The line-shaped or lattice-shaped adhesive layer 24 may have a line width smaller than the diameter of the through-hole 14, and it does not matter whether the lines are separated from each other or whether the lines are parallel. The adhesive layer 24 on which a number of figures are arranged only needs to have a diameter smaller than the diameter of the through-hole 14, and the distribution state of the figures is not particularly limited. However, if the figures are regularly distributed,
It is preferable that the distance between the edges of the adjacent figures is not “r−r ₂ + S” (r = hole diameter of the through hole, r ₂ = diameter of the figure, S = the distance between the edges of the adjacent through holes and the edge). . Depending on the relationship between the shape of the figure and the shape of the through hole, all the figures may enter the inside of the through hole, making it impossible to bond the ink absorbing member and the transparent recording material. (FIG. 8). The specific shape of the figure is not particularly limited, and examples thereof include a circle, an ellipse, a semicircle, and a polygon. Further, the shape of the figure may be a donut shape in which only the outer peripheral portion of the illustrated shape is formed of an adhesive and the inside is hollow.

Production Material 3 for Transparent Display of the Present Invention
Are the above-described transparent recording material 1 and ink absorbing member 2
Are laminated (FIGS. 2 to 5). In this case, it is essential that the ink absorbing member 2 can be removed from the laminate.

The means for laminating is not particularly limited as long as it satisfies the above essential requirements. For example, the use of an adhesive or a tape, or the recording material 1 that can be seen through
3 is used (FIG. 3), and when the ink absorbing member 2 has the ink absorbing adhesive layer 23, the adhesive property of the ink absorbing adhesive layer 23 is used (FIG. 3). 4) When the ink absorbing member 2 has the adhesive layer 24, the adhesive property of the adhesive layer 24 is used (FIG. 5),
There is a method in which the recording material 1 and the ink absorbing member 2 which can be seen through are adhered so as to be peelable. It is to be noted that a method in which the transparent recording material 1 and the ink absorbing member 2 are simply overlapped with each other may be used. However, the above-described means of temporarily bonding the two members with an adhesive or the like is more suitable for recording with an inkjet printer. This is preferable because the positions of the two members are not displaced inside, and there is little risk of causing unevenness in an image or soiling the inside of the ink jet printer or the back surface of the transparent recording material 1.

[0049] Transparent recording material 1 and ink absorbing member 2
As a method of peelably adhering between the adhesive, a method of adjusting the adhesive force of the adhesive used itself, a method of reducing the adhesive force by partially contacting the adhesive with the adherend (for example, In addition to a matrix adhesive layer in which an adhesive is formed in a matrix shape, there is a method in which a release treatment is performed in advance on a surface opposite to the recording surface of the transparent recording material 1.

The ink receiving layer 12 and the adhesive layer 13 are coated with a coating solution obtained by dissolving or dispersing the resin or the like in a solvent by a known coating method such as bar coating. It can be formed by drying.

The visible display material is obtained by laminating the above-described transparent recording material 1 and the ink absorbing member 2, recording an image thereon by an ink jet printer, and then removing the ink absorbing member 2. Can be.

When the transparent display material thus obtained has the adhesive layer 13, as shown in FIG. 9 or FIG. 11, the ink receiving layer 12 has a hot melt resin, a thermoplastic resin, In the case of containing a crystalline plasticizer, it is used by sticking to the window glass 4 as shown in FIG. When the transparent display itself does not have the above-described adhesive performance, an adhesive is separately applied on the ink receiving layer 12 or on the surface on the side opposite to the ink receiving layer 12, and the like, and Affixed. The see-through display attached to the window glass 4 can be viewed from the inside to the outside through the presence of the large number of through-holes 14, while the person on the outside can see the image facing the outside. Attention is deprived, and the effect that it is hard to see the inside is exhibited.

As described above, according to the production material 3 for a see-through display object of the present invention, the purchaser can easily form the original image without using a punch press and without staining the inside of the ink jet printer. A transparent display object can be manufactured.

Next, a method for producing a transparent display object of the present invention will be described.

First, a plurality of through-holes 14 are provided, and a portion other than the through-holes 14 is provided on a surface opposite to an ink-jet recordable surface of the see-through recording material 1 having concealing properties and ink-jet recording characteristics. Then, the ink absorbing member 2 is laminated (FIGS. 2 to 5).

Next, an image 5 is output by an ink jet printer on the ink jet recordable surface of the obtained laminate.

Next, by removing the ink absorbing member 2 from the laminate, a transparent display is obtained.

As described above, according to the method for producing a see-through display object of the present invention, a see-through display object composed of an original image can be easily produced.

Next, the adhesive layer 24 and the release film 15 of the transparent recording material 1 obtained above were bonded together to obtain a transparent display material production material 3 (FIG. 5). In addition, the obtained see-through display material production material 3 was peelable between the adhesive layer 24 and the release film 15.

The material 3 for the visible display material obtained in Example 1 was composed of the recording material 1 and the ink absorbing member 2 which were visible.
After sticking the four sides together with a double-sided tape so that both can be peeled off (FIG. 2), the material 3 for the transparent display object obtained in Examples 2 to 5 is left as it is (FIGS. 3 to 3). 5) An image was output using an inkjet printer (BJC-420J: Canon Inc.).

Next, the ink absorbing member 2 was peeled off and removed from the material 3 for forming a see-through display on which an image was recorded, to obtain a see-through display. When the displayable object obtained in this manner was used by attaching it to the window glass 4 so that the image was on the outside (see FIGS. 9 to 11), all of the objects could be viewed from the inside to the outside. However, it was difficult to see the inside from the outside.

The material 3 for the transparent display material of Examples 1 to 5 can easily produce the transparent display material composed of the original image without polluting the inside of the ink jet printer. Met. In addition, none of the back surfaces of the obtained transparent display objects were stained with the undried ink.

[0098] The products of Examples 2 and 5 have the adhesive layer 13 and can be directly adhered to the window glass 4 or the like, and are excellent in convenience (FIG.
11). Further, when affixed to the window glass 4, since the window glass 4 side was black, it was easy to visually recognize the outside from the inside.

Examples 3 and 4 can be attached to a window glass 4 or the like by heating, and an image is sandwiched between the window glass 4 and a base material 11 having concealment. Therefore, the weather resistance was excellent (FIG. 10).

Further, according to the method for manufacturing a see-through display object of the embodiment, a see-through display object composed of an original image could be easily manufactured. Further, since the transparent recording material 1 and the ink absorbing member 2 are temporarily bonded to each other, the positions of the two members do not shift during recording by the inkjet printer. The back surface of the obtained displayable object was not stained.
