Problems solved by technology

[0005] However, for example, in the case of high-speed printing on non-absorbing recording media such as coated paper, coated paper, and plastic film, or low-absorbing recording media using the above-mentioned inks, the bleeding of the color boundary between inks of different hues cannot be sufficiently suppressed practically. color, as a result, high-quality printed matter may not be obtained

Embodiment

[0289] Hereinafter, the present invention will be described in further detail through examples.

[0290] (Preparation method of polymer (P-1))

Synthetic example 1

[0292] The hexane solution of BuLi and the styrene solution prepared by dissolving styrene in tetrahydrofuran were prepared from figure 1 The shown tubular reactors P1 and P2 are introduced into a T-shaped micro-mixer M1 to perform living anion polymerization to obtain a polymer.

[0293] Next, pass the polymer obtained in the above process through figure 1 The tubular reactor R1 shown moves to the T-shaped micromixer M2, and the growth terminal of the above-mentioned polymer is captured by the reaction regulator (α-methylstyrene (α-MeSt)) introduced from the tubular reactor P3 .

[0294] Next, a solution of tert-butyl methacrylate obtained by dissolving tert-butyl methacrylate in tetrahydrofuran in advance was figure 1 The shown tubular reactor P4 is introduced into the T-shaped micro-mixer M3 to carry out continuous living anionic polymerization reaction with the above-mentioned captured polymer moving through the tubular reactor R2. Then, the aforementioned living anioni...

[0346] (Manufacturing method of production example 1 aqueous pigment dispersion (C-1))

[0347] 150 parts by mass of phthalocyanine-based pigment FASTOGEN BLUE Pigment (manufactured by DIC Co., Ltd.: C.I. Pigment 15:3), 45 parts by mass of polymer (P-1), 150 parts by mass of triethylene glycol, 20 parts by mass of A 34% by mass potassium hydroxide aqueous solution was charged into a 1.0 L intensive mixer (EIRICH Corporation, Japan), and kneaded for 25 minutes at a rotor peripheral speed of 2.94 m / s and a disc peripheral speed of 1 m / s.

[0348] Next, while continuing to stir, 450 parts by mass of ion-exchanged water was slowly added to the kneaded product in the above-mentioned intensive mixer container, and then 185 parts by mass of ion-exchanged water was further added and mixed to obtain an aqueous solution with a pigment concentration of 15% by mass. Pigment Dispersion (C-1).

Abstract

The present invention addresses the problem of providing an ink-set which can form a printed matter on which bleeding and color mixing are reduced. The ink-set according to the present invention comprises a black pigment ink (a) having a static surface tension (a1) in the range of 20-40 mN / m, and at least one pigment ink (b) selected from the group consisting of magenta pigment inks and yellow pigment inks, wherein the static surface tension of the pigment ink (b) is lower than the static surface tension (a1) by 0.1-0.7 mN / m.

Description

technical field [0001] The present invention relates to an ink set that can be used when producing printed matter by inkjet recording. Background technique [0002] Pigment inks for inkjet recording have been studied for printing on various media such as plain paper, coated paper, coated paper, plastic film, metal, and cloth because they can form printed matter excellent in light fastness and the like. [0003] In particular, with the rapid development of the Print On Demand (Print On Demand) market in recent years, it is required to be able to print inkjet recording water-based pigment inks on recording media at high speed, and to be able to produce prints comparable to those obtained by lithography. High quality print. [0004] In order to print high-quality printed matter at high speed, it is necessary to suppress bleeding at the color boundary between inks of different hues. As a method of preventing the bleeding between the above-mentioned inks, for example, the follo...
