Problems solved by technology

[0010] However, for the ink-receiving layer described in the above-mentioned documents, for example, when inkjet printing is carried out on relatively large media such as outdoor advertisements, since the organic solvent contained in the ink cannot be sufficiently absorbed, the ink sometimes dries. Significant reduction in performance or bleeding or cracking of printed images, etc.
[0011] In addition, the ink-receiving layer described in the above-mentioned Patent Document 1 is formed using an ink-jet-receiving agent in which the above-mentioned specific acrylic resin is dissolved in an organic solvent. Therefore, when producing an ink-jet recording medium, it may be necessary to volatilize a large amount of the organic solvent. process
[0012] As mentioned above, the actual situation is that it has not been found that even when printing with oil-based pigment ink, it is possible to form a printed image that is difficult to bleed, crack or fade, etc., has excellent drying properties, and is excellent in water resistance. Aqueous inkjet receptor for the receptor layer of the image of the color density

Embodiment 1

[0109] Example 1

[0110] 115 parts by mass of deionized water and 4 parts by mass of LATEMUL E-118B (manufactured by Kao Corporation: active ingredient 25% by mass) were added to a reaction vessel equipped with a stirrer, a reflux cooler, a nitrogen gas introduction tube, a thermometer, and a dropping funnel, and While blowing in nitrogen gas, the temperature was raised to 75°C.

[0111] Add 0.1 mass parts of potassium persulfate to the reaction vessel while stirring, and continue to add a part (5 mass parts) of 60.0 mass parts of methyl methacrylate, 1.0 mass parts of methacrylic acid as a carboxyl-containing vinyl monomer, A vinyl monomer mixture consisting of 2.0 parts by mass of acrylamide and 37.0 parts by mass of butyl acrylate as an amide group-containing vinyl monomer, and 4 parts by mass of AQUALON KH-1025 (manufactured by Daiichi Kogyo Pharmaceutical Co., Ltd.: active ingredient 25 % by mass) and 15 parts by mass of deionized water were mixed and polymerized for 6...

Abstract

Disclosed is an inkjet accepting agent for oily pigment ink prepared by dispersing a vinyl polymer (A) having a glass transition temperature of 10-70 DEG C obtained by polymerizing a vinyl monomer mixture containing 30-70 wt% of methyl methacrylate (a1) and a total of 0.2-5.0 wt% of at least one selected from the group comprising a carboxyl group containing vinyl monomer (a2) and an amide group containing vinyl monomer (a3) in an aqueous medium (B), wherein the elution rate when said vinyl polymer (A) is immersed in 25 DEG C tetrahydrofuran for 24 h is 10-90 wt%. Also disclosed is an inkjet recording medium for oily pigment ink having an ink accepting layer obtained by using same.

Description

technical field [0001] The present invention relates to an inkjet receptor for oil-based pigment ink, an inkjet recording medium for oil-based pigment ink having an ink-receiving layer formed using the same, and a printed matter printed with the oil-based pigment ink. Background technique [0002] In recent years, in the rapid development of inkjet printing related industries, the high performance of inkjet printers and the improvement of ink have been rapidly developed. Image. Therefore, not only the use of inkjet printers in the home was studied, but also their use in the manufacture of large billboards was started. [0003] In addition, the improvement of the image quality of inkjet printed matter depends not only on the improvement of the performance of the above-mentioned printers, but also largely on the improvement of printing inks. Specifically, the use of pigment inks known as inks capable of forming printed images having high color rendering properties comparable...
