Description

  The present invention relates to a recording material for an ink jet printer, and relates to an ink having good recording characteristics for both water-based ink and solvent-based ink.

  In recent years, with the spread of computers, hard copy technology has been rapidly developed. As a hard copy recording system, a sublimation transfer recording system, an electrophotographic recording system, an ink jet recording system, and the like are known.

  An ink jet printer is a printer that uses an ink jet recording method that ejects ink droplets from a nozzle toward a recording material at a high speed, and is easy to colorize and miniaturize and has low printing noise. In recent years, it has been rapidly spreading as a terminal such as a personal computer.

  As the ink used in the ink jet recording method, a so-called aqueous ink using water and a lower alcohol as a solvent has been mainly used. This is because the water-based ink is capable of vivid color recording, is easy to adjust the viscosity of the ink, and is excellent in safety. However, there is a problem that water-based ink is inferior in water resistance.

  In recent years, solvent-based inks such as paraffin-based inks and thinner-based inks have been developed. These solvent-based inks are promising as alternatives to water-based inks in fields that require high-speed recording, high-quality recording, and high water resistance.

  However, although these solvent-based inks are excellent in water resistance, paraffin-based inks have a drawback that they easily damage recording materials and protective films. In addition, the thinner ink has a problem that it has a strong odor, has a large influence on the environment, and is dangerous, and therefore requires a person with a specific qualification when handling it.

  Therefore, glycol-based inks mainly composed of glycol ether and alkylene glycol have been developed. This ink is a newly developed solvent-based ink, which is excellent in water resistance and eliminates the above-mentioned drawbacks of conventional solvent-based inks.

  On the other hand, various ink jet recording materials have been proposed according to the ink used. For example, those for water-based inks include those of Patent Documents 1 and 2, and those for solvent-based ink include those of Patent Documents 3 to 5.

  However, there has not yet been proposed an ink jet recording material that can be recorded satisfactorily for any of water-based inks and solvent-based inks (particularly glycol-based inks among solvent-based inks).

  In addition, since it was easy for bleeding to occur, the conventional ink jet recording material had a sufficient thickness in the ink receiving layer to prevent bleeding. However, when the thickness of the ink receiving layer is large, when the ink receiving layer is transferred to the adherend, the texture of the adherend is impaired, or the ink receiving layer cannot follow the shape of the adherend, and the ink There has been a problem that wrinkles enter the receiving layer or the ink receiving layer breaks.

JP-A-8-132727 (Claim 1) JP-A-10-329405 (Claim 1) JP-A-11-99742 (Claim 1) JP-A-11-165460 (Claim 1) JP 2003-266922 A (Claim 1)

  The present invention has been made in view of the above-described circumstances, and provides an ink jet recording material that can satisfactorily record with both water-based inks and solvent-based inks (particularly glycol-based inks among solvent-based inks). With the goal. It is another object of the present invention to provide an ink jet recording material capable of preventing bleeding even when the ink receiving layer is thin.

Jet recording material of the present invention for solving the above-mentioned problem, in the ink jet recording material having an ink-receiving layer, said ink-receiving layer, at least, Ri Na is formed from an acrylic-modified polyester resin emulsion, and polyvinyl pyrrolidone, wherein the polyester resin The polyvinyl pyrrolidone is contained in an amount of 30 to 80 parts by weight with respect to 100 parts by weight of the emulsion .

  Preferably, the ink receiving layer is formed on a support, and the support can be removed from the ink jet recording material.

  In the ink jet recording material of the present invention, since the ink receiving layer is formed of at least an acrylic-modified polyester resin emulsion and a water-soluble resin, water-based inks and solvent-based inks (particularly glycol-based inks among solvent-based inks). The recording can be performed satisfactorily for any of the inks. In addition, since the ink jet recording material of the present invention can prevent bleeding even if the thickness of the ink receiving layer is thin, when used as a transfer application, the texture of the adherend is prevented from being impaired. In addition, it is possible to prevent wrinkles in the ink receiving layer and cracking of the ink receiving layer during the transfer operation.

  The ink jet recording material of the present invention is an ink jet recording material having an ink receiving layer, wherein the ink receiving layer is formed of at least an acrylic-modified polyester resin emulsion and a water-soluble resin. Hereinafter, embodiments of each component will be described.

  The ink receiving layer can be divided into those that can be handled by the ink receiving layer alone, such as those obtained by forming a resin constituting the ink receiving layer into a film, and those that are difficult to handle by the ink receiving layer alone. When it is difficult to handle the ink receiving layer alone, the ink receiving layer is formed on the support. The support is not particularly limited, but a plastic film made of a polyester resin, a polycarbonate resin, a polyvinyl chloride resin, a polyethylene resin, a polypropylene resin, a polystyrene resin, or the like, paper, fiber cloth, or the like can be used. . The thickness of the support is not particularly limited, but is preferably 5 μm or more in terms of conveyance.

  The ink receiving layer is formed of at least an acrylic-modified polyester resin emulsion and a water-soluble resin. By using such a resin composition for the ink receiving layer, it is possible to improve the recording characteristics for both water-based ink and solvent-based ink, and to increase the thickness of the ink receiving layer. In addition, bleeding of water-based ink can be prevented.

  The acrylic-modified polyester resin emulsion can be obtained by polymerizing a polyester resin dispersed in water and an acrylic resin in water. Specifically, a radical polymerization initiator is added to an aqueous dispersion of a polyester resin, and a vinyl monomer is added under a condition of 45 to 85 ° C. to advance the reaction.

  As described above, the acrylic-modified polyester resin has a role of imparting recording characteristics to the solvent-based ink. Furthermore, the acrylic-modified polyester resin can appropriately increase the surface tension of the ink receiving layer, and can effectively prevent bleeding of water-based ink.

  The polyester resin component of the acrylic modified polyester resin can be obtained from a polybasic acid or an ester-forming derivative thereof and a polyol or an ester-forming derivative thereof. Polybasic acid components include terephthalic acid, isophthalic acid, phthalic acid, phthalic anhydride, 2,6-naphthalenedicarboxylic acid, 1,4-cyclohexanedicarboxylic acid, adipic acid, sebacic acid, trimellitic acid, pyromellitic acid, And dimer acid. The polyol component includes ethylene glycol, 1,4-butanediol, diethylene glycol, dipropylene glycol, 1,6-hexanediol, 1,4-cyclohexanedimethanol, xylene glycol, dimethylolpropane, and poly (ethylene oxide) glycol. And poly (tetramethylene oxide) glycol. These monomers can be used alone or in combination of two or more.

  Examples of the acrylic resin component of the acrylic modified polyester resin include various vinyl monomers. For example, methyl (meth) acrylate, ethyl (meth) acrylate, 2-hydroxyethyl (meth) acrylate, acrylamide, methacrylamide, N-methyl (meth) acrylamide, N-methylol (meth) acrylamide, N, N-dimethylacrylamide , Glycidyl (meth) acrylate, acrylic acid, methacrylic acid, itaconic acid, maleic acid, maleic anhydride, itaconic anhydride, vinyl isocyanate, allyl isocyanate, styrene, vinyl methyl ether, vinyl ethyl ether, vinyl trialkoxysilane, alkyl malein Acid monoesters, alkyl fumaric acid monoesters, acrylonitrile, methacrylonitrile, vinylidene chloride, ethylene, propylene, vinyl chloride, vinyl acetate, butadiene, etc. Ma and the like. These monomers can be used alone or in combination of two or more.

  The ratio of the polyester resin component and the acrylic resin component in the acrylic modified polyester resin is preferably 10 to 100 parts by weight of the acrylic resin component with respect to 100 parts by weight of the polyester resin component.

  The water-soluble resin imparts recording characteristics to water-based ink. Water-soluble resins include synthetic resins such as polyvinyl alcohol, polyvinyl pyrrolidone, hydroxycellulose, melamine resin, acrylic acid, acrylic ester, nylon, acrylamide copolymer, and natural resins such as gelatin, casein, starch, chitin, and chitosan. can give. Among these, polyvinyl pyrrolidone that easily absorbs solvent-based ink is preferably used.

  The addition ratio of the acrylic-modified polyester resin emulsion and the water-soluble resin forming the ink receiving layer is preferably 20 to 150 parts by weight of the water-soluble resin with respect to 100 parts by weight of the acrylic-modified polyester resin emulsion. More preferred is 80 parts by weight. By setting such an addition ratio, it is possible to improve the recording characteristics for both water-based ink and solvent-based ink, and further, without increasing the thickness of the ink receiving layer, the water-based ink. Bleeding can be prevented.

  The thickness of the ink receiving layer is not particularly limited, but is preferably 70 μm or less as an upper limit in order to prevent curling. The lower limit of the thickness is generally 5 μm or more in order to prevent ink bleeding, particularly water-based ink bleeding. However, in the present invention, even if the thickness of the ink receiving layer is less than 5 μm, bleeding of the water-based ink can be prevented. This is because the surface tension of the ink receiving layer is reasonably high, so that ink that is not quickly absorbed by the ink receiving layer does not spread and spread on the surface of the ink receiving layer and is gradually absorbed by the ink receiving layer. It is done. On the other hand, when the surface tension of the ink receiving layer is low, the ink spreads and spreads on the surface of the ink receiving layer, and when the surface tension is too high, the spherical ink moves on the surface of the ink receiving layer, and the ink It becomes uneven unevenness.

  As described above, in the present invention, even if the thickness of the ink receiving layer is reduced, the recording characteristics of the water-based ink are not affected. Therefore, it can be suitably used for transfer applications that require a thin ink-receiving layer. When used as a transfer application, the thickness of the ink receiving layer is preferably 0.5 to 5 μm, and more preferably 1 to 3 μm. By setting the thickness of the ink receiving layer to 0.5 μm or more, bleeding can be prevented, and by setting the thickness to 5 μm or less, it can be suitably used for transfer applications. When there is no support and the ink receiving layer is handled alone, it is preferably 3 μm or more in view of conveyance.

  The ink receiving layer may contain a resin other than the acrylic-modified polyester resin and the water-soluble resin as long as the above-described performance is not impaired. Such resins include polyvinyl butyral resin, polyester resin (excluding those modified with acrylic), epoxy resin, vinylidene chloride resin, vinyl chloride-acrylic copolymer resin, vinyl chloride-vinyl acetate copolymer resin, chlorine Polyolefin resin, urethane resin, alkyd resin, rubber resin and the like. However, the total of the acrylic-modified polyester resin and the water-soluble resin is preferably 80% by weight or more, more preferably 90% by weight or more of the total resin components in the ink receiving layer.

  The ink receiving layer of the ink jet recording material of the present invention has good recording characteristics even when the thickness is small, and the thickness of the ink receiving layer transferred to the adherend can be reduced, so that the texture of the adherend is impaired. Therefore, the ink receiving layer is not wrinkled or cracked during transfer, and can be suitably used for transfer applications. In particular, the adherend can be suitably used when the surface of the adherend is curved or uneven, or when the adherend is flexible and deforms.

  When used for such a transfer application, it is preferable that the ink receiving layer is formed on a support, and the support can be removed from the ink jet recording material. In order to achieve such a configuration, for example, the surface of the support on which the ink receiving layer is formed is subjected to a release treatment with a silicone release agent, and the release treatment surface and the ink receiving layer are separated. For example, it is possible to provide a peeling adjustment layer and an ink receiving layer on the support in order, and to allow peeling between the peeling adjustment layer and the support. The peeling adjustment layer has a weak adhesive force with the support and is firmly bonded to the ink receiving layer. For example, when the support is a polyester film, the peeling adjustment layer may be composed of polyvinyl alcohol, nylon, or the like. preferable.

  In order to transfer the ink receiving layer to the adherend, (1) a method of forming an adhesive layer on the ink receiving layer, attaching the adhesive layer to the adherend, and then removing the support; (2 ) A method in which one side of a double-sided adhesive sheet is attached on the ink receiving layer, the other side of the double-sided adhesive sheet is attached to an adherend, and then the support is removed. The ink receiving layer may be transferred to the adherend before or after recording on the ink receiving layer. However, in the case of a type having a peeling adjustment layer, since the peeling adjustment layer may not sufficiently transmit ink, it is preferable to perform transfer after recording. When the ink receiving layer is transferred after recording, the recording is performed as a mirror image.

  When the ink receiving layer is transferred to the adherend, it is preferable to add a plasticizer to the ink receiving layer in order to impart flexibility. Examples of the plasticizer include phthalate ester, adipate ester, phosphate ester, trimellitic ester, citrate ester, epoxy, polyester, and polyhydric alcohol plasticizers. Among these, a polyhydric alcohol plasticizer capable of imparting flexibility without impairing recording characteristics is preferable. The addition amount of the plasticizer is preferably 40 parts by weight or less, and more preferably 5 to 25 parts by weight with respect to 100 parts by weight of the total resin of the ink receiving layer.

  The ink receiving layer may contain a pigment in order to improve ink absorbability or prevent blocking. In addition to inorganic pigments such as silica, clay, talc, calcium carbonate, calcium sulfate, barium sulfate, aluminum silicate, titanium oxide, synthetic zeolite, alumina, smectite, styrene resin, urethane resin, benzoguanamine resin, silicone resin, Organic pigments such as resin beads made of acrylic resin or the like, or hollow resin beads made from these are used, and these can be used alone or in combination. The addition amount of the pigment is usually about 3 to 200 parts by weight with respect to 100 parts by weight of the total resin of the ink receiving layer.

  In the ink receiving layer, additives such as a leveling agent, an ultraviolet absorber, an antioxidant, and a chelating agent may be added.

  As a method for forming the ink receiving layer, a coating liquid is prepared by dissolving or dispersing the constituents of the ink receiving layer in an appropriate solvent, and the coating liquid is roll coating, bar coating, spray coating, air knife coating. The method of apply | coating and drying on a support body by well-known methods, such as a method, is mention | raise | lifted. However, the drying temperature is higher than the minimum film-forming temperature of the acrylic-modified polyester resin emulsion.

  In order to prevent the occurrence of curling, a back coat layer is provided on the surface of the support opposite to the ink receiving layer, or to prevent charging, the ink receiving layer is opposite to the ink receiving layer of the support or the support. An antistatic layer may be provided on the side surface.

As is apparent from the results in Table 2, the ink jet recording materials of Reference Example 1, Example 2 to Example 5, and Reference Examples 6 and 7 in which the ink receiving layer is formed from an acrylic-modified polyester resin emulsion and a water-soluble resin are as follows. The recording properties of water-based ink and solvent-based ink were excellent. In particular, the ink-jet recording materials of Examples 2 to 5 are particularly suitable for the recording characteristics of water-based inks and solvent-based inks because the acrylic-modified polyester resin emulsion and the water-soluble resin polyvinyl pyrrolidone are mixed in an optimum range. It was excellent.

  On the other hand, the ink jet recording materials of Comparative Examples 1 to 8 were inferior in the recording characteristics of the water-based ink and the solvent-based ink as compared with the ink jet recording materials of the examples.

[Comparative Example 16]
An inkjet recording material of Comparative Example 16 was obtained in the same manner as Comparative Example 8 except that the thickness of the ink receiving layer of Comparative Example 8 was changed to 3 μm.

The inkjet recording materials obtained in Reference Example 8 , Examples 9 to 12, Reference Examples 13 and 14, and Comparative Examples 9 to 16 were recorded with an inkjet printer ("PM-7000C: EPSON") using water-based ink. The printability was evaluated in the same manner as described above. Table 3 shows the results.
Shown in

(1) Bleeding prevention Bleeding of the printed portion of the inkjet recording material after recording was visually observed. As a result, “◯” indicates that there is no bleeding, “Δ” indicates that it is slightly blurred, and “x” indicates that it does not become an image due to bleeding.

(2) Unevenness of the printed portion “○” indicates that the ink is not unevenly uneven in the printed portion of the ink jet recording material after recording, “△” indicates that the ink is slightly unevenly uneven and the ink is slightly uneven. Those markedly biased and extremely uneven were marked with “x”.

As is apparent from the results in Table 3, the inkjet recording materials of Reference Example 8 , Examples 9 to 12, and Reference Examples 13 and 14 in which the ink receiving layer is formed of an acrylic-modified polyester resin emulsion and a water-soluble resin are inks. Despite the thin receiving layer of 2.5 μm, the water-based ink has excellent recording characteristics. In particular, since the ink-jet recording materials of Examples 9 to 12 have an acrylic modified polyester resin emulsion and polyvinyl pyrrolidone mixed in an optimal range, the recording characteristics of water-based inks are particularly good even when the ink receiving layer is thin. It was excellent.

  On the other hand, the inkjet recording materials of Comparative Examples 9 to 16 were inferior to the recording characteristics of the water-based ink when the thickness of the ink receiving layer was reduced as compared with the inkjet recording materials of the examples.

  Comparative Example 10 in which the ink receiving layer was formed at a ratio of 40 parts by weight of polyvinyl pyrrolidone to 100 parts by weight of the unmodified polyester resin emulsion showed relatively good results, but the acrylic-modified polyester resin emulsion The recording characteristics are inferior to those of Example 10 in which the ink receiving layer is formed at a ratio of 40 parts by weight of polyvinylpyrrolidone to 100 parts by weight. Therefore, it has been shown that the acrylic modified polyester resin emulsion is superior in recording characteristics as compared with the unmodified polyester resin emulsion.

  Next, on a 75 μm thick separator (Diafoil MRF75: Mitsubishi Chemical Polyester Film Co., Ltd.), a pressure-sensitive adhesive layer coating solution having the following composition was applied by a bar coating method so that the thickness after drying was 20 μm. A pressure-sensitive adhesive layer was formed by drying at 120 ° C. for 3 minutes, and a similar separator was bonded onto the adhesive layer to obtain a double-sided adhesive sheet having separators on both sides.

<Pressure-sensitive adhesive layer coating solution>
・ Acrylic pressure sensitive adhesive 60 parts (SK Dyne 1604S: Soken Chemicals, solid content 42%)
・ Ethyl acetate 20 parts ・ Toluene 20 parts

Next, the separator on one side of the double-sided adhesive sheet was peeled off and bonded to the recording surface of the inkjet recording sheets of Reference Example 8 , Examples 9-12, Reference Examples 13, 14 and Comparative Examples 9-16 after recording. . Next, the opposite surface of the double-sided adhesive sheet was bonded to a part of the adherend (commercial telephone handset). Next, the support was removed from the ink jet recording material, a double-sided adhesive sheet was bonded to the remaining part of the adherend, and the ink receiving layer was transferred to the adherend. As a result, those of Reference Example 8 , Examples 9 to 12, and Reference Examples 13 and 14 do not impair the texture of the adherend, and the transfer workability is good without causing wrinkles in the ink receiving layer. It was something. Further, the recorded state of the image of the transferred ink receiving layer was good.

  On the other hand, in Comparative Examples 9 to 16, although the transfer workability was good, the recording state of the image of the transferred ink receiving layer was unclear.
