【発明の詳細な説明】
〔産業上の利用分野〕
本発明はボールペンインキ用組成物、更に詳しく言えば

が得られるとともに、滲みの少ない描線を与えるなど、
優れた特性を有するボールペン用水性顔料インキ組成物
に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a composition for ballpoint pen ink, and more specifically, a composition for ballpoint pen ink, which has excellent long-term dispersion stability of pigments, and has good lubricity.
It prevents wear on the tip's ball holder, provides a smooth brush feel, and provides lines with less smearing.
The present invention relates to a water-based pigment ink composition for ballpoint pens that has excellent properties.
従来、ボールペンに用いられる水性顔料インキとしては
、水や水溶性有機溶剤などの水性媒体に、分散剤として
界面活性剤や水溶性樹脂などを用い、顔料を分散させた
ものが知られている。Conventionally, water-based pigment inks used in ballpoint pens are known in which pigments are dispersed in an aqueous medium such as water or a water-soluble organic solvent using a surfactant, a water-soluble resin, or the like as a dispersant.
しかしながら、このような水性顔料インキにおいては、
チップのボールホルダーの摩耗によって筆感が劣化した
り、あるいはチップの劣化によってインキの流出が不均
一になったりするなどの欠点を有している。However, in such water-based pigment inks,
It has disadvantages such as the writing feel deteriorates due to wear of the ball holder of the tip, and the ink flows unevenly due to the deterioration of the tip.
このような欠点を改良する目的で、潤滑性向上剤として
例えば不飽和脂肪酸の塩等の添加することが試みられて
いる。しかしながら、これらはその添加量が少ないと、
潤滑効果が発揮されないし、また、多くするとボールホ
ルダーの摩耗が少なく、書味もよくなるが、描線の滲み
が著しく、実用的でないと言う問題があった〇
〔発明が解決しようとする課題〕
本発明の目的は、潤滑性に優れ、ボールペンのチップの
摩耗が少なく、滑らかな筆感が得られ、書味が良好であ
るとともに、滲みが少なく、かつ耐光性や耐水性に優れ
た描線を与えることができる上に、顔料の長期分散性に
も優れた水性顔料インキ組成物を提供することである。In order to improve these drawbacks, attempts have been made to add, for example, salts of unsaturated fatty acids as lubricity improvers. However, if the amount added is small,
It does not have a lubricating effect, and although increasing the amount reduces wear on the ball holder and improves the writing quality, there is a problem that the drawn line blurs significantly and is not practical.〇 [Problem to be solved by the invention] Book The purpose of the invention is to provide a ballpoint pen with excellent lubricity, less wear on the tip of a ballpoint pen, a smooth writing feel, good writing taste, less bleeding, and excellent light and water resistance. It is an object of the present invention to provide an aqueous pigment ink composition which is capable of dispersing pigments and has excellent long-term dispersibility of pigments.

低減させて潤滑作用をもたらしているものと推察する。(Effects) The water-based pigment ink composition of the present invention has excellent long-term dispersion stability of the pigment, good lubricity, prevents wear of the ball holder of the tip, and provides a smooth brush feel.
It has excellent properties such as providing drawn lines with little smearing. Although it is not clear why it has these properties, the polyoxyalkylene glycol allyl alkyl ether/maleic acid derivative copolymer or polyoxyalkylene glycol-2-methylallyl which is the lubricating component used in the present invention The alkylene glycol group, which is a hydrophilic group in the alkyl ether/maleic acid derivative copolymer, is adsorbed and oriented on the metal surface of the ballpoint pen tip holder and ball, and the alkyl group, which is a hydrophobic group, is oriented thereon. It is inferred that this reduces the coefficient of friction between the ball and the ball holder, providing a lubricating effect.
