Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink jet recording material and a method for manufacturing the ink jet recording material.

[0002]

2. Description of the Related Art Various output recording methods such as a wire dot recording method, a thermosensitive color recording method, a thermal melting transfer recording method, a thermosensitive sublimation transfer recording method, an electrophotographic recording method, and an ink jet recording method are available as output prints of a computer or a word processor. Is being developed. Among them, the ink jet recording method has features such as low printing cost, a compact apparatus, no noise, and high-speed recording. For this reason, this ink jet recording system has been attracting attention as a recording system capable of quickly and accurately outputting image information such as characters and figures created by a computer or the like.

[0003] In addition, the ink-jet recording system is easy to colorize and the picture pattern is clear, so that image information created by a computer can be printed out without deterioration of the image quality. Since it is also printable, it can be used not only for office and personal use, but also for outdoor advertisements and exhibitions, such as signs for movies and entertainments, and signboards for stations, and has attracted attention in recent years.

[0004] When producing a printed material for use in an advertisement or exhibition in the field using such an ink jet recording method, the recording material for ink jet is required to have not only sharpness and color forming property of the printing but also a printing property. Since the water-based ink needs to be quickly absorbed and dried, it needs to have an appropriate hydrophilicity, and the ink is required to have fixability and water resistance so that the printed surface is not destroyed by rainwater or the like. Further, there is a demand for an inkjet recording material having a glossy surface in order to improve the appearance.

Therefore, in response to such a demand,
As an ink jet recording material capable of clearly printing an image such as a figure or a photograph, a material having an ink receiving layer containing a water-soluble resin and an inorganic filler formed on a substrate has been proposed. . However, when the hydrophilicity of the ink receiving layer is increased by using a water-soluble resin in order to improve the image quality and the drying property of the ink, the water resistance is impaired, and in order to maintain the water resistance, the water-soluble Increasing the crosslinking of the resin will decrease the drying properties of the ink.

[0006] The printability can be improved by using a resin having excellent water resistance and adding an inorganic filler, but in this case, the surface of the ink receiving layer can be improved by adding the inorganic filler. There is a problem that the surface of the recording material for ink jet recording loses its luster because the surface is not smooth.

Therefore, as a method for producing an ink jet recording material having a glossy surface on the ink receiving layer, an ink receiving layer is formed using a resin containing a solvent, and then a film sheet is pressed on the ink receiving layer. A method has been proposed in which, after drying, the film sheet is peeled off and transferred to produce an inkjet recording material having a surface gloss. However, this method has a problem that the number of steps is increased due to the necessity of a step of removing the solvent, and that the film sheet needs to have adhesiveness to the ink receiving layer.

As described above, the conventional ink jet recording material satisfies the printing suitability and water resistance, such as clearness and color development of printing, absorption and drying of ink during printing, and fixing of ink, and , Those with surface gloss have not been obtained,
In particular, it has been difficult to satisfy the above requirements when using an aqueous pigment-based ink.

[0009]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention is not only excellent in printability, water resistance, and ink drying and absorption properties, but also has a surface gloss, and is not limited to dye-based inks. An object of the present invention is to provide a recording material for inkjet which is suitable for use in outdoor advertising / exhibition and the like, and a method for manufacturing the recording material for inkjet, which can also use a pigment-based ink.

[0010]

The present invention relates to an ink jet recording material having an ink receiving layer provided on a base material, wherein the glossiness measured at an incident angle of 60 ° is 45 or more; The ink jet recording material is characterized in that the drying time of the ink is within 20 minutes. Hereinafter, the present invention will be described in detail.

The recording material for ink jet of the present invention comprises a base material and an ink receiving layer provided on the base material. The material of the base material is not particularly limited, for example, polyethylene terephthalate resin, polycarbonate resin, acrylic resin, polyvinyl chloride resin, polypropylene resin, polystyrene resin, polyvinyl alcohol resin, polyethylene resin, diacetate resin, triacetate resin, polyimide Resins and the like can be mentioned.

The shape of the substrate is preferably a film or plate. The thickness of the substrate is 5 to
250 μm is preferable, and 50 to 180 μm is more preferable. If the thickness of the base material is less than 5 μm, the handleability may be poor, and if it exceeds 250 μm, the production cost may be high, which may be economically disadvantageous. The surface of the substrate on which the ink receiving layer is provided is preferably subjected to a primer treatment or a corona treatment from the viewpoint that the adhesive strength between the substrate and the ink receiving layer can be enhanced.

The primer used in the above-mentioned primer treatment is not particularly restricted but includes, for example, alkyd resin, polyester resin, polyvinyl acetate resin, vinyl chloride / vinyl acetate copolymer resin, NBR resin, SBR resin, polyurethane resin and acrylic resin. , Polyamides, mixtures and modified products thereof.

It has improved adhesiveness, hydrophilicity and the like.

When the substrate has a surface on which the ink receiving layer is not provided, an anti-curl layer or an antistatic layer may be provided on the surface. Examples of the material of the curl prevention layer include a water-soluble resin, an acrylic resin, a modified acrylic resin, and a polyester resin, which are the same as the water-soluble resin that can be used for the underlayer described later. Among these, acrylic resins, modified acrylic resins and polyester resins are preferred from the viewpoint that excellent blocking resistance and slip properties can be imparted.

The thickness of the anti-curl layer is not particularly limited, but is preferably 0.1 to 50 μm as a dry thickness. Further, when the same ink receiving layer is provided on both surfaces of the base material, not only the curl preventing effect can be obtained, but also the remarkable effect of reducing the haze of the entire inkjet recording material can be obtained.

The ink receiving layer preferably comprises at least one underlayer and a surface gloss layer formed on the underlayer. As a material of the underlayer, a composition containing a hydrophilic resin and an inorganic filler (hereinafter, also referred to as a composition for the underlayer) is preferable.

Examples of the hydrophilic resin include water-absorbing alkyd resins, polyester resins, polyvinyl acetate resins, vinyl chloride / vinyl acetate copolymer resins, NBR resins, SBR resins, polyurethane resins, urea resins, and acrylic resins. , Polyamides, mixtures and modified products thereof. The modified product is, for example, by copolymerizing or graft-polymerizing a monomer or the like containing a hydroxyl group, a carboxylic acid, a quaternary ammonium salt, or the like to the resin or a monomer serving as a raw material thereof, to thereby improve adhesiveness, hydrophilicity, and the like. It has been improved. The above hydrophilic resins may be used alone or in combination of two or more.

As the inorganic filler, for example, porous particles can be used. Specifically, for example, silica, clay, talc, diatomaceous earth, calcium carbonate, calcium sulfate, barium sulfate, aluminum silicate, synthetic zeolite, smectite, montmorillonite group minerals,
Examples include synthetic mica, alumina, titanium oxide, and zinc oxide. These inorganic fillers may be used alone or in combination of two or more.

The amount of the inorganic filler is preferably 50 to 500 parts by weight based on 100 parts by weight of the hydrophilic resin. If the amount of the inorganic filler is less than 50 parts by weight, the ink drying property may not be sufficiently improved.
If it exceeds 0 parts by weight, sufficient strength as a coating film may not be obtained.

The underlayer composition may contain a water-soluble resin, an organic filler, and other additives in addition to the hydrophilic resin and the inorganic filler. The water-soluble resin is not particularly limited as long as it is soluble in water or a mixed solvent of water and alcohol. For example, polyvinyl alcohol, polyvinyl pyrrolidone, poly (meth) acrylic acid, carboxymethyl cellulose (CMC), Cellulose resins such as hydroxyethyl cellulose (HEC) and hydroxypropyl cellulose (HPC), polyacrylamide, polyethylene oxide, polyethylene glycol, polyvinyl acetal resin, polyvinyl methyl ether, polyamine, polyethylene imine, casein, gelatin, starch, and the like Examples thereof include polymers and modified cations / anions. These water-soluble resins may be used alone or in combination of two or more.

When the above-mentioned water-soluble resin is contained in the above-mentioned composition for an underlayer, the amount of the above-mentioned water-soluble resin is not particularly limited.
1 to 50 parts by weight is preferred. When the amount of the water-soluble resin is less than 1 part by weight, the effect of improving the drying property and the absorbability of the ink may not be obtained. The layer may elute and break.

The organic filler is not particularly limited.
For example, those obtained by making the water-soluble resin water-absorbing and / or water-insoluble by crosslinking can be mentioned. Specific examples thereof include polyvinyl alcohol, polyacrylate,
Polymethacrylate, polystyrene, benzoguanamine / formaldehyde condensate, benzoguanamine /
Melamine / formaldehyde condensate, melamine / formaldehyde condensate, polyamide-based resin, various celluloses, starches, and those obtained by crosslinking these; water-absorbing alkyd resins, polyester resins, polyvinyl acetate resins,
Vinyl chloride / vinyl acetate copolymer resin, NBR resin, SB
Examples thereof include R resins, polyurethane resins, acrylic resins, polyamides, and mixtures and modified products thereof.
These organic fillers may be used alone or in combination of two or more. The modified product is, for example, by copolymerizing or graft-polymerizing a monomer or the like containing a hydroxyl group, a carboxylic acid, a quaternary ammonium salt, or the like to the resin or a monomer serving as a raw material thereof, to thereby improve adhesiveness, hydrophilicity, and the like. It has been improved.

When the above-mentioned organic filler is contained in the underlayer composition, the amount of the above-mentioned organic filler is not particularly limited, but is preferably 100 parts by weight of the above-mentioned hydrophilic resin.
1 to 50 parts by weight is preferred. When the amount of the organic filler is less than 1 part by weight, the effect of improving the drying property and the absorbability of the ink may not be obtained. The layer may elute and break. In addition, the retention of the solvent may rather deteriorate the ink drying property.

Examples of other additives include a surfactant, an emulsifier, an antioxidant, an antifoaming agent, a leveling agent, an antioxidant and the like. When a surfactant or an emulsifier is used as another additive, the dispersion stability of the inorganic filler or the like in the photosensitive resin can be improved. When the above-mentioned other additives are contained in the underlayer composition, the amount of the other additives is not particularly limited, and the hydrophilic resin to be compounded, the properties of the inorganic filler, etc., It may be appropriately selected in consideration of physical properties and the like.

The thickness of the underlayer is 1 to 50 μm.
Is preferred. If the thickness of the underlayer is less than 1 μm, it may not be possible to impart sufficient ink drying and absorption properties to the ink receiving layer. If the thickness is more than 50 μm, the production cost becomes high, which is economically disadvantageous. It may be.
The underlayer may be provided in two or more layers in consideration of the adhesion between the gloss layer and the substrate sheet, but usually, only one layer sufficiently fulfills the role described later.

Since the ink receiving layer has an underlayer formed using the underlayer composition, the ink has excellent drying and absorbing properties at the time of printing. The reason for this is that the absorption of the ink solvent is covered by a base layer that is more absorbent than the gloss layer.

As a material of the surface gloss layer, a composition containing a photosensitive resin and an inorganic filler (hereinafter, also referred to as a composition for a surface gloss layer) is preferable. Examples of the photosensitive resin include KJP-960B manufactured by Nippon Kayaku Co., Ltd. Examples of the inorganic filler include those similar to the inorganic filler used in the underlayer composition.

The amount of the inorganic filler is not particularly limited, but may be 1 to 100 parts by weight of the photosensitive resin.
0 to 150 parts by weight is preferred. If the amount of the inorganic filler is less than 10 parts by weight, a sufficient effect on the ink absorbency and drying property may not be obtained. If the amount is more than 150 parts by weight, the filler holding power of the ink receiving layer becomes insufficient. In some cases, the shape of the ink receiving layer cannot be maintained as a film.

The composition for a surface gloss layer may contain a water-soluble resin, a hydrophilic resin, an organic filler, and other additives in addition to the photosensitive resin and the inorganic filler. The water-soluble resin, hydrophilic resin, organic filler, and
Examples of the other additives include those similar to those used in the composition for the underlayer.

When the water-soluble resin is contained in the composition for a surface gloss layer, the amount of the water-soluble resin is not particularly limited, but is preferably 1 to 50 parts by weight based on 100 parts by weight of the photosensitive resin. Is preferred. If the amount of the water-soluble resin is less than 1 part by weight, a sufficient effect on the ink absorbency and drying property may not be obtained, and if it exceeds 50 parts by weight, the water resistance of the ink receiving layer is impaired, May elute.

When the hydrophilic resin is contained in the composition for a surface gloss layer, the amount of the hydrophilic resin is not particularly limited, but is 1 to 50 parts by weight based on 100 parts by weight of the photosensitive resin. Is preferred. If the amount of the hydrophilic resin is less than 1 part by weight, a sufficient effect on the ink absorption and drying properties may not be obtained, and if it exceeds 50 parts by weight, the water resistance of the ink receiving layer is impaired, May elute.

When the above-mentioned organic filler is contained in the composition for a surface gloss layer, the amount of the above-mentioned organic filler is not particularly limited, but 1 to 30 parts by weight based on 100 parts by weight of the above-mentioned photosensitive resin. Is preferred. If the amount of the organic filler is less than 1 part by weight, a sufficient effect on the ink absorption and drying properties may not be obtained. If the amount exceeds 30 parts by weight, the ink absorption and drying properties may deteriorate. And may cause bleeding.

When the above-mentioned other additives are contained in the composition for a surface gloss layer, the amount of the other additives is not particularly limited, and the properties of the photosensitive resin and inorganic filler to be compounded and the surface gloss The layer may be appropriately selected in consideration of desired physical properties and the like.

Although the thickness of the ink receiving layer is not particularly limited, it is preferably 1 to 50 μm in a dry thickness,
-30 μm is more preferable. If the thickness of the ink receiving layer is less than 1 μm, the ink may not be sufficiently absorbed. If the thickness is more than 50 μm, the production cost may be increased, which may be economically disadvantageous.

The ink-jet recording material having such a structure has a glossiness of 4 measured at an incident angle of 60 °.
Since it is as large as 5 or more, it is excellent in appearance and is most suitable for use in outdoor advertisements and exhibitions. The glossiness is 45
If it is less than 1, the gloss of the surface of the recording material for inkjet is insufficient, and the appearance of the printed image may be poor. The gloss measured under the condition of the incident angle of 60 ° is an index indicating the degree of gloss of the surface, and the reflected light at the reflection angle of 60 ° is measured with respect to the incident light at the incident angle of 60 °. The calculated value is calculated as a percentage of the value of the reflected light when the reference surface is measured under the same conditions. In addition, about the method of giving the glossiness of the above range to the inkjet recording material,
Details will be described later.

The drying time of the ink of the ink jet recording material is excellent within 20 minutes, so that a clear image can be obtained without bleeding of the ink. Also, immediately after printing, it can be used for purposes such as advertisement. If the drying time of the ink exceeds 20 minutes, bleeding of the ink may occur, and a clear image may not be obtained. Also,
Workability and productivity during printing may be degraded.

The ink which can be used for the recording material for ink jet is not particularly limited, and any dye-based ink or pigment-based ink can be suitably used.

Further, a printed material using the above-described recording material for inkjet has the above-described characteristics, so that it can maintain the sharpness of the printed material even when left outdoors for at least about one year. It is suitable for use in exhibitions. Further, the above-mentioned recording material for ink jet can be suitably used as a recording material for home use and office use.

As a method of manufacturing the recording material for inkjet, at least one underlayer is provided on a base material, and then a surface gloss layer is provided on the underlayer.

Since the film sheet 15 is peeled off from the ink receiving layer 14 after photocuring, it is preferable that the film sheet 15 has a lower adhesiveness to the ink receiving layer 14 and a higher peeling property than the substrate 11. Examples of the material of the film sheet 15 include polyethylene terephthalate resin, polycarbonate resin,
Examples include acrylic resin, polyvinyl chloride resin, polypropylene resin, polystyrene resin, polyvinyl alcohol resin, polyethylene resin, diacetate resin, triacetate resin, and polyimide resin.

The thickness of the film sheet 15 is 5 to
250 μm is preferable, and 50 to 180 μm is more preferable. In addition, in order to improve the releasability of the film sheet 15, a material obtained by treating the surface of the film sheet with silicon, fluorine, or the like may be used. In the present invention, the film sheet 15 is in the form of a film, but is not limited to the film, but may be in the form of a plate.

Next, the surface gloss layer 13 on which the film sheet 15 is pressed is irradiated with ultraviolet rays or the like to be light-cured. Further, after the surface glossy layer 13 is light-cured, FIG.
By peeling the film sheet 15 from the ink receiving layer 14 as shown in (b), the ink receiving layer 14 having the glossy surface 13a is formed. As described above, by pressing the film sheet 15 on the ink-coated surface side of the ink-receiving layer 14, the glossy surface 13a can be provided on the ink-coated surface side of the ink-receiving layer 14.

As described above, according to the method for manufacturing an ink jet recording material of the present invention, the process of forming (transferring) a glossy surface and the process of curing can be performed simultaneously, and the film sheet also has an adhesive layer. There is no need to be. Therefore, with a small number of processes, without defective products, with good yield,
An ink jet recording material having excellent printability and water resistance and having a surface gloss can be produced.
