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 comprising two types of ink receiving layers having different ink absorbing properties, and more particularly to an ink receiving material having excellent dye ink and pigment ink receptive performance, and having a good printing quality of the pigment ink. The present invention relates to an ink jet recording material that can be easily corrected.

[0002]

2. Description of the Related Art Ink jet recording is one of the most popular printing methods along with electrophotographic printing (PPC), and various recording materials which have been subjected to a dedicated image receiving process to obtain good images have been proposed. There are dye-based and pigment-based inks. Dye inks have good color developability, but are slightly inferior in weather resistance, and pigment inks have slightly inferior color developability, but have excellent weather resistance, and have advantages and disadvantages such as high concentration being easily obtained even with a small amount of dispersing solvent.

In recent years, ink jet recording apparatuses using both such dye inks and pigment inks have also been used. However, the dye inks and pigment inks have different image receiving and fixing mechanisms. The required performance also differs.

The dye of the dye ink discharged from the ink jet recording apparatus to the ink receiving layer is absorbed into the ink receiving layer together with the solvent and fixed in the resin of the ink receiving layer, but the pigment in the pigment ink is dispersed. The pigment is discharged to the ink receiving layer together with the solvent, and only the dispersion solvent is absorbed in the ink receiving layer, whereby the pigment is deposited and fixed on the ink receiving layer.

[0005] For this reason, as one of the ink receiving performances required in the case of the dye ink, it is desired that the ink dryness is excellent with the increase in the ink amount due to the recent colorization. On the other hand, as one of the ink receiving performances required for the pigment ink, it is desired that the pigment coating deposited and fixed on the ink receiving layer does not crack due to swelling of the ink receiving layer caused by absorption of the dispersion solvent. It is rare.

[0006] Further, there are applications that use an ink jet recording material to output drawings such as design and drafting.
In this case, the drawings are often superimposed, and a highly transparent ink jet recording material may be desired.

In the case of such a purpose of outputting a drawing or the like, when the data of the drawing or the like is stored as digital data, the amount of information of the data becomes enormous and it may take time to output. . Therefore, in such a case, even if there is a minor defect in the printed content, the minor defect should be erased without re-outputting, and the writing location should be easily corrected with a writing instrument such as a pencil, ink pen or ballpoint pen. It is also hoped that it can be done.

However, when erasing minor defects, the erasing method in which the printed content is scraped together with the ink receiving layer using a sand eraser, a sword or the like, the ink receiving layer is lost and the transparent plastic film is exposed. As a result, there arises a problem that writing cannot be corrected and a correction portion is conspicuous.

As a method for solving such a problem, Japanese Patent Application Laid-Open No. Hei 7-25138 discloses a structure in which a matte-treated substrate is provided with a removable ink receiving layer on the matte-treated surface, and after printing, a necessary ink-receiving layer is provided. An ink jet recording material has been proposed in which writing can be corrected even when the ink receiving layer at the corrected portion is removed, and the corrected portion is inconspicuous.

The present invention is a very effective means since both the dye ink and the pigment ink can be erased and the writing can be corrected. However, when erasing with a sword or a sand eraser, a strong force is applied. There is a problem that the matte-treated surface is damaged or a large area is hardly erased, so that there is no method that anyone can easily erase.

In many of the ink jet recording apparatuses using both the dye ink and the pigment ink, black is mainly a pigment ink and the color is often a dye ink. Therefore, if the application is to output a drawing or the like that is mostly drawn with black pigment ink, the printed content of the pigment ink can be easily erased and corrected with a general plastic eraser instead of a sword or sand eraser. Is very much desired.

However, up to now, there has been no ink jet recording material which satisfies the above-mentioned requirements for the dye ink and the pigment ink at one time, and which can easily correct the printed content of the pigment ink.

[0013]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an ink jet recording material which is excellent in ink acceptability for dye inks and pigment inks and which can easily modify the printed contents of pigment inks. There.

[0020]

BEST MODE FOR CARRYING OUT THE INVENTION The ink jet recording material of the present invention will be described in more detail.

As described above, the ink jet recording material of the present invention is obtained by forming a first ink receiving layer and a second ink receiving layer each containing a binder resin and a pigment on at least one surface of a transparent plastic film. is there.

As described above, by incorporating a pigment into a binder resin as an ink receiving layer, a large amount of ink accompanying full-color ink jet recording can be quickly absorbed by utilizing a void formed in the ink receiving layer by the pigment. Drying performance (hereinafter referred to as “ink drying property”) can be improved.

Examples of the pigments contained in the binder resin include inorganic pigments such as silica, clay, smectite, mica, talc, titanium oxide, zinc oxide, calcium carbonate, barium sulfate, and aluminum oxide;
Organic pigments such as silicone, cellulose, and polystyrene are exemplified.

Here, as an important constituent element in the present invention, the content of the pigment with respect to the binder resin is made different between the first ink receiving layer and the second ink receiving layer, and the pigment content in the first ink receiving layer is changed. The content is to be greater than the pigment content in the second ink receiving layer, and the thickness of the first ink receiving layer is to be greater than the thickness of the second ink receiving layer. By doing so, the performance of preventing the occurrence of cracks in the pigment film deposited and fixed on the ink receiving layer, which is one of the pigment ink receptive properties (hereinafter referred to as “pigment printing suitability”), is reduced. In addition, the printing contents of the pigment ink (the contents drawn with the pigment film deposited and fixed on the ink receiving layer) can be easily erased with a plastic eraser or the like without removing the ink receiving layer, and the same location can be written with a writing instrument. This can be a factor in exhibiting the ability to correct the writing (hereinafter, referred to as “print content correctability”).

Therefore, in order to improve such an effect, the thickness of the second ink receiving layer is set to 0.5 to 5 μm.
m, preferably 1 to 3 μm, and the laminated thickness of the first ink receiving layer and the second ink receiving layer formed sequentially is 5 μm or more, preferably 10 μm or more.

Here, the thickness of the second ink receiving layer is set to 0.5
The value of μm or more increases the parallel light transmittance by obtaining more sufficient correction of printed content and filling the unevenness of the mat surface formed by the pigment of the first ink receiving layer with the second ink receiving layer slightly. In order to improve transparency, the thickness is set to 5 μm or less, in order to obtain more satisfactory pigment printing suitability, and to not overfill the unevenness of the mat surface formed by the pigment of the first ink receiving layer, and to use the writing implement. This is because the writability by the above is not reduced.

The reason why the laminated film thickness of the first ink receiving layer and the second ink receiving layer is set to 5 μm or more is to obtain more sufficient ink drying property.

In order to further improve these effects,
The pigment content of the first ink receiving layer is adjusted by the binder resin 10
The pigment content is 60 to 120 parts by weight, preferably 70 to 110 parts by weight with respect to 0 parts by weight, and the pigment content of the second ink receiving layer is 5 to 60 parts by weight, preferably 10 to 10 parts by weight with respect to 100 parts by weight of the binder. It is effective to set it to 50 parts by weight.

Here, the pigment content of the first ink receiving layer is defined as
The amount of 60 parts by weight or more is intended to make the pigment content of the first ink receiving layer larger than the pigment content of the second ink receiving layer in the first place so that the pigment printability can be more sufficiently obtained. The reason why the content is set to 120 parts by weight or less is to make print content correctability more sufficient.

The pigment content of the second ink receiving layer is set to 5
The amount of not less than part by weight is for more sufficient ink drying property, and the amount of not more than 60 parts by weight is for more sufficient print content correction and transparency. Further, the reason why the pigment content of the second ink receiving layer is set to 5 parts by weight or more is an effect of improving a blocking phenomenon in which the ink jet recording materials are stuck to each other when the ink jet recording materials are stored in layers. In order to obtain

Another important component in the present invention is that the resin component of the binder resin of the first ink receiving layer and the binder resin of the second ink receiving layer formed on at least one surface of the transparent plastic film in order is 40%. ~ 6
In this case, 0 parts by weight of a water-soluble resin and 60 to 40 parts by weight of a hydrophilic resin are used. Accordingly, by interacting with the difference in the pigment content and the difference in the film thickness of the first ink receiving layer and the second ink receiving layer, the ink receiving performance for the dye ink and the pigment ink, which is the object of the present invention, Is satisfied at a time, and the print contents can be corrected.

Here, both of the first ink receiving layer and the second ink receiving layer are contained in 100 parts by weight of the binder resin.
The reason why the amount of the water-soluble resin is 40 parts by weight or more and the amount of the hydrophilic resin is 60 parts by weight or less is to obtain ink drying property which is one of the ink receiving performances of the dye ink. The reason why the water-soluble resin is 60 parts by weight or less and the hydrophilic resin is 40 parts by weight or more in 100 parts by weight of the binder resin of the first ink receiving layer is to obtain pigment printing suitability, The reason why the content of the water-soluble resin is set to 60 parts by weight or less and the content of the hydrophilic resin is set to 40 parts by weight or more in 100 parts by weight of the binder resin of the receiving layer is to obtain correctability of printed contents.

In general, a hydrophilic resin has a dissociative group such as a carboxyl group, a sulfonic acid group and a quaternary amine group, or a nonionic group such as a hydroxyl group, an acrylamide group and an ether group. Is a natural polymer, a semi-synthetic polymer, or a synthetic polymer having a hydrophilic group, and is considered to mean a resin that dissolves in or swells with water. Then, the hydrophilic resin will contain a water-soluble resin, but in the present invention, the water-soluble resin is defined as a resin that dissolves in water, and the hydrophilic resin swells with water, but a resin that does not dissolve in water. Define.

Examples of such a water-soluble resin or hydrophilic resin include albumin, gelatin, casein, starch,
Arabic gum, natural resins such as sodium alginate, carboxymethylcellulose, hydroxyethylcellulose,
Polyamide, polyacrylamide, polyhydroxyethyl methacrylate, polyphenylacetoacetal, polyvinylacetal, polyvinylformal, polyethyleneimine, polyvinylpyrrolidone, polyvinylpyridium halide, melamine resin, polyurethane, polyvinyl alcohol, polyester, sodium polyacrylate,
It can be appropriately selected from synthetic resins such as acrylate copolymers.

In particular, the water-soluble resin of the first ink-receiving layer is polyvinyl alcohol, and the hydrophilic resin is an acrylic resin comprising a copolymer of at least a monomer containing a carboxyl group and a (meth) acrylic acid alkyl ester. By neutralizing a part of the groups with an imidazole compound, the first ink receiving layer can be provided with excellent color developability and preservability for the dye ink, and extremely excellent dye ink receptivity can be obtained. Will be able to

In the second ink receiving layer, the water-soluble resin is polyvinylpyrrolidone and the hydrophilic resin is at least two.
By using a basic acrylic resin comprising a copolymer of at least two kinds of hydrophilic monomers and at least two kinds of lipophilic monomers, the compatibility between the water-soluble resin and the hydrophilic resin constituting the second ink receiving layer can be improved. As a result, the pigment printability can be more stably obtained.

The basic acrylic resin further contains at least 2-hydroxyethyl (meth) acrylate and 2-dimethylaminoethyl (meth) acrylate as hydrophilic monomers, and at least (meth) acrylic as a lipophilic monomer. Methyl acrylate and n- (meth) acrylate
By including butyl, it is possible to more stably obtain the printability.

The binder resin used in the first ink receiving layer and the second ink receiving layer satisfies the ink receiving performance for the dye ink and the pigment ink at one time and at the same time inhibits the effect of obtaining the correctability of the printed contents. If the amount is not more than 20 parts by weight based on 100 parts by weight of the binder resin, a lipophilic resin other than the water-soluble resin and the hydrophilic resin may be added.

After the binder resin or pigment described above is appropriately dissolved and diluted with an organic solvent such as alcohol or water, and then diluted on at least one surface of the transparent plastic film by a conventionally known coating method. By sequentially forming the first ink receiving layer and the second ink receiving layer, respectively, it is possible to obtain an ink jet recording material that solves the problem of the present invention.

As the transparent plastic film in this case, for example, polyester, polycarbonate, cellulose acetate, polyimide, polyethylene, polystyrene, polypropylene, polyvinyl chloride and the like can be used.

[0064]

[Table 1]

As is clear from the results shown in Table 1, the ink jet recording materials of Examples 1 and 2 exhibited excellent properties in all of the ink drying property, pigment printing suitability, and print content correcting property. In particular, the ink jet recording material of Example 2 is
For the first ink receiving layer, polyvinyl alcohol is used as a water-soluble resin, and an acrylic resin comprising a copolymer of at least a carboxyl group-containing monomer and a (meth) acrylic acid alkyl ester is used as a hydrophilic resin. By using a material whose part was neutralized with an imidazole-based compound, the coloring property for the dye ink was superior to that of the ink jet recording material of Example 1.
In the ink jet recording material of Example 2, polyvinyl pyrrolidone was used as the water-soluble resin in the second ink receiving layer, and at least 2-hydroxyethyl (meth) acrylate and (meth) acrylate were used as hydrophilic monomers.
By using a basic acrylic resin containing 2-dimethylaminoethyl acrylate and containing at least methyl (meth) acrylate and n-butyl (meth) acrylate as the lipophilic monomer, the pigment printability and The print content correctability can be obtained more stably.

On the other hand, in the ink jet recording material of Comparative Example 1, the second ink receiving layer was not laminated on the first ink receiving layer, and the pigment content of the first ink receiving layer on which the pigment ink was deposited and fixed was high. As a result, the print content correctability is reduced.

In the ink jet recording material of Comparative Example 2, the binder resin component of the second ink receiving layer was 20 parts by weight of a water-soluble resin and 80 parts by weight of a hydrophilic resin. As a constituent of the binder resin component, the proportion of the water-soluble resin was reduced and the proportion of the hydrophilic resin was increased, so that the ink drying property was reduced.

As a constituent of the binder resin component, the proportion of the hydrophilic resin was decreased and the proportion of the water-soluble resin was increased, so that the suitability for pigment printing was reduced.

In the ink jet recording material of Comparative Example 4, the binder resin component of the second ink receiving layer was 80 parts by weight of a water-soluble resin and 20 parts by weight of a hydrophilic resin. As the constituent binder resin component, the proportion of the hydrophilic resin was reduced and the proportion of the water-soluble resin was increased, so that the suitability for pigment printing and the property of correcting the printed contents were reduced.

In the ink jet recording material of Comparative Example 5, the pigment content of the first ink receiving layer was 1%.
The pigment printing suitability was reduced because the amount was reduced to 20 parts by weight with respect to 00 parts by weight, and the pigment content of the second ink receiving layer was increased to 100 parts by weight with respect to 100 parts by weight of the binder resin. In this case, the printability was poor.

In the ink jet recording material of Comparative Example 6, since the thickness of the second ink receiving layer was thicker than that of the first ink receiving layer and was as large as 7 μm, the suitability for pigment printing was lowered. Was.
