【発明の詳細な説明】 （Ａ）産業上の利用分野 本発明は平版印刷用インキ添加物に関するものである。[Detailed description of the invention] (A) Industrial application field The present invention relates to lithographic printing ink additives.
（Ｂ）従来技術及びその問題点
平版印刷版は油脂性のインキを受理する親油性の画線部
分とインキを受けつけない發油性の非画線部からなり、
一般に非画線部は水を受けつける親水性部分から構成さ
れる。従って、通常の平版印刷はインキと水の両方を版
面に供給し、画線部は着色性のインキと水の両方を版面
に供給し、画線部は着色性のインキを非画線部は水を選
択的に受入れ、画線上のインキを例えば紙などの基質に
転写されることによってなされている。湿し水を使用す
る平版印刷版としては、ジアゾニウム化合物を用いたプ
レセンシタイズド版（いわゆるＰＳ版）、酸化亜鉛や有
機光導電体を用いた電子写真方式による平版印刷版、ハ
ロゲン化銀乳剤を感光成分として用いた銀塩写真方式に
よる平版印刷版などが知られており、そのような平版印
刷版での印刷に使用されるインキにも多種多様なものが

合によっては全く使用することができないこともある。(B) Prior art and its problems A lithographic printing plate consists of an oleophilic image area that accepts oil-based ink and an oleophilic non-image area that does not accept ink.
Generally, the non-image area is composed of a hydrophilic area that receives water. Therefore, in normal lithographic printing, both ink and water are supplied to the plate surface, both colored ink and water are supplied to the printing area, and colored ink is supplied to the printing area, and colored ink is supplied to the non-printing area. This is done by selectively admitting water and transferring the ink on the image to a substrate such as paper. Lithographic printing plates that use dampening water include presensitized plates (so-called PS plates) that use diazonium compounds, electrophotographic lithographic printing plates that use zinc oxide or organic photoconductors, and silver halide emulsions. Lithographic printing plates based on silver halide photography using lithographic printing plates as photosensitive components are known, and a wide variety of inks are also known for use in printing with such lithographic printing plates. However, with conventional printing inks, even if good prints can be obtained when using a specific printing plate or dampening solution, the type and printing conditions may change. This causes various drawbacks, and in some cases, it may not be possible to use it at all.

好な界面適性を与え、地汚れを防止しインキ濃度の高い
良好な印刷物を得ることができる。It goes without saying that the properties required of such printing ink are that a sufficient amount of ink adheres to the printed areas and that no ink adheres to non-printed areas. Furthermore, it is necessary to consider fluidity, interfacial suitability, drying properties, etc. Particularly in planographic printing, oil-based ink and water are repeatedly supplied to the plate surface for each printing page during the printing of thousands to tens of thousands of sheets, so the interfacial tension and surface tension between the oil-based ink and water If it does not have an appropriate balance, the print area will gradually expand or disappear, cause emulsification of the ink, or cause background smudges. Japanese Patent Application Laid-open No. 138677/1982, Patent Application No. 19493/1983
No. 3 describes a lithographic printing ink additive comprising a compound having an alkylene oxide unit. Indeed, the compounds disclosed in these patents provide ink with good interfacial suitability, prevent background smearing, and make it possible to obtain good printed matter with high ink density.

うという重大な欠点を有している。However, when ink containing these compounds is used to print on printing paper that does not easily absorb solvents, such as art paper or coated paper, or when these compounds are added to ultraviolet curing ink, the ink of printed matter may deteriorate. It has the disadvantage of slow drying. On the other hand, it is well known that fine particles such as colloidal silica having an average particle size of 0.1 micron (μ) or less are used in various plate surface treatment solutions following the development treatment of such silver salt lithographic printing plates. For example, the dampening liquid of JP-A-48-45305, JP-A-54-8350
2, neutralizing liquid, desensitizing liquid, and dampening liquid in Japanese Patent Application No. 104176/1983, fixing agent (liquid), and dampening liquid in Japanese Patent Publication No. 45-29001. However, it is generally believed that inorganic fine particles such as colloidal silica and colloidal alumina adsorb to the surface of the lithographic printing plate, create a hydrophilic layer on the surface of the printing plate, and improve hydrophilicity. Not only has it not been possible to fully achieve the most desired objective of preventing stains caused by printing ink, but it also has the serious drawback of inhibiting the spread of ink in the image area.
