【発明の詳細な説明】
〔発明の目的〕
（産業上の利用分野）
本発明は、有機溶剤型グラビア印刷インキに関

中の溶剤が浸透するような紙質の被印刷物に印刷
する際に、その浸透性が著しく軽減されたグラビ
ア印刷インキに関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to an organic solvent-based gravure printing ink, and more particularly, the present invention relates to an organic solvent type gravure printing ink, and more particularly, the present invention relates to an organic solvent type gravure printing ink, and more particularly, the present invention relates to an organic solvent-based gravure printing ink. This invention relates to a gravure printing ink whose permeability is significantly reduced when printing on paper substrates.
（従来の技術）
従来より、有機顔料に樹脂、界面活性剤等で処
理した顔料組成物を用いて、印刷インキの流動性
改良や光沢改良がなされることが知られている。(Prior Art) It has been known that the fluidity and gloss of printing inks can be improved by using pigment compositions in which organic pigments are treated with resins, surfactants, etc.
しかしながら有機顔料の樹脂処理として一般的

剤の浸透が抑制できないため、印刷物の光沢や濃
度が著しく劣つたり、両面印刷ができない等の問
題があつた。 However, with rosin resin, which is commonly used as a resin treatment for organic pigments, even though fluidity and gloss have been improved, for example, the solvent used as the printing substrate for publishing gravure printing ink, which is an organic solvent type, can penetrate. Since the penetration of the solvent cannot be suppressed for such paper quality, there have been problems such as the gloss and density of the printed matter are significantly inferior and double-sided printing is not possible.
すなわち、以上のような従来の処理方法で得ら

望されるに伴い、低廉紙において顕著な前記裏抜
けという問題のない印刷インキが必要とされた。
なお従来裏抜けに対処するために、グラビア印刷
インキの粘度を調整することも行われていたが、
粘度調整は印刷適性の上から望ましくない。 In other words, when a pigment composition obtained by the conventional processing method as described above is used in an organic solvent type gravure printing ink, when printing on a low-cost paper surface, the pigment penetrates into the back side of the paper, which is called bleed-through. This caused problems such as printed matter becoming smeared or double-sided printing being impossible. In particular, in recent years, there has been a strong desire to reduce the manufacturing cost of printed matter by changing the paper used for printing from high-quality processed paper to inexpensive paper. No printing ink was required.
In addition, in the past, the viscosity of gravure printing ink was adjusted to deal with strike-through, but
Viscosity adjustment is undesirable from the viewpoint of printability.
（発明が解決しようとする問題点）

ていることが示されている。 Incidentally, as a treatment for pigments, a treatment method using a styrene-maleic anhydride resin is also conventionally known. This pigment composition is being studied primarily for use in writing instrument inks and paints. In particular, it has been shown that pigment compositions treated with water-soluble styrene-maleic anhydride resins have excellent dispersibility and compatibility with vehicle resins in water-based paints, writing instrument inks, and the like.
