（従来の技術）
従来より、ボールペン用水性インキとしては着

顔料インキ（特公昭55−35434、特開昭58−
80368、特開昭58−141256）が見られる様になり、
ボールペン用インキとしても水性顔料インキ使用

（発明が解決しようとする問題点）
然し乍ら、従来の水性顔料インキをボールペン
に使用した場合、ボールの回転が円滑にいかず、
筆跡が掠れたり、筆記時、紙面とペン先が引つか
かるなど、書き味を損う場合が多々あるといつた
問題を有している。
かかる問題の解決のため界面活性剤の使用が考

（問題点を解決するための手段）
そこで、本発明者等は上記問題点を解決する目

（式中（）中、Ｒ＝C5〜C20のアルキル基
ｎ＝５〜50の整数を示す。）
（作用）
本発明の水性顔料インキが何故、ボールペン使

本発明に使用されるアルキル置換フエノールの
エチレンオキサイド付加物は上記合金の表面（特

基）が配向し、疎水基（アルキル基）が上記合金
の表面を覆う為に、潤滑作用をもたらしボールの
回転がスムースになり、結果的に書き味が良好に
なるものと推察される。
（発明の構成）
次に本発明の水性顔料インキの各成分について
説明する。
顔料は着色剤として使用するもので、従来公知
の有機及び無機顔料が全て使用可能であるが、そ
の具体例を挙げると、アゾ系顔料、縮合ポリアゾ
系顔料、フタロシアニン系顔料、ジオキサジン系
顔料、ペリノン・ペリレン系顔料、キナクリドン
系顔料、カーボンブラツク系顔料等が使用でき、
その使用量はインキ全量に対して１〜20重量％、
好ましくは３〜10重量％である。
分散剤としては通常使用される分散剤が使用可
能であり、その具体例を挙げると、アクリル酸、
メタアクリル酸系樹脂エマルジヨン、酢酸ビニル
系樹脂エマルジヨン、天然樹脂系分散剤、ノニオ
ン又はアニオン界面活性剤などある。
溶剤としては、水の他に、染料タイプの水性イ
ンキに用いられている水溶性有機溶剤が使用可能
であり、その具体例を挙げると、グリコール系溶
剤、グリコールエーテル系溶剤、グリコールエー
テルエステル系溶剤、グリセリン、ピロリドンな
どがある。
前記アルキル置換フエノールのエチレンオオキ
サイド付加物の使用料は0.1〜４重量％である。
0.1重量％より少ないと効果が明確でなく、10重
量％より多いとインキ粘度が高くなり過ぎたり、
分散系が破壊され凝集し易くなる。
尚、このアルキル置換フエノールのエチレンオ
キサイド付加物のアルキル基は炭素数５〜20のも
のであり、具体的には、ペンチル、イソペンチ
ル、ネオペンチル、ヘキシル、イソヘキシル、３

(Industrial Application Field) The present invention relates to a water-based pigment ink, and more particularly to a water-based ink for ballpoint pens that has excellent writing feel. (Prior Art) Conventionally, water-based inks for ballpoint pens have generally used dyes as colorants, but they have had problems such as poor water resistance. On the other hand, recently, water-based pigment inks using pigments as colorants (Japanese Patent Publication No. 55-35434, Japanese Patent Publication No. 58-1989)
80368, JP-A-58-141256) became available.
Water-based pigment inks are increasingly being used as inks for ballpoint pens. (Problems to be Solved by the Invention) However, when conventional water-based pigment inks are used in ballpoint pens, the ball does not rotate smoothly.
It has many problems, such as blurred handwriting and the nib getting stuck to the paper when writing, which often impairs the writing quality. The use of surfactants may be considered as a solution to this problem, but if they are added in the amount necessary to obtain the effect, new problems arise such as destruction of the pigment dispersion system and blurring of handwriting. It is also possible to use polymeric carboxylic acids, higher alcohol esters, metal soaps, etc., but in this case too, problems such as destruction of the pigment dispersion system and blurring of handwriting occur, and neither of these problems can be sufficiently solved. I haven't reached it yet. (Means for Solving the Problems) Therefore, in order to solve the above problems, the present inventors have conducted extensive research and found that conventional aqueous pigment inks contain ethylene oxide adducts of certain alkyl-substituted phenols. By adding an appropriate amount of
It was discovered that a water-based pigment ink with excellent writing quality can be obtained when used in a ballpoint pen, and the present invention was completed. That is, the present invention provides an aqueous pigment ink consisting of at least a pigment, a dispersant, a water-soluble organic solvent, and water, in which an ethylene oxide adduct of an alkylphenol represented by the following general formula () is added to the total amount of the ink. The gist thereof is a water-based pigment ink for ballpoint pens characterized by containing 0.1 to 4% by weight. (In the formula (), R = an alkyl group of C 5 to C 20 , and n = an integer of 5 to 50.) (Function) Why is the aqueous pigment ink of the present invention excellent in writing quality when using a ballpoint pen? Although it is not certain, it is inferred as follows. Ballpoint pen tips require precision machining, so free-cutting alloys are used. Examples of free-cutting alloys include ferrite or martensitic stainless steel, nickel silver, and brass, and cemented carbide (tungsten carbide) is the mainstream ball material. In the ethylene oxide adduct of alkyl-substituted phenol used in the present invention, water-soluble groups (polyethylene oxide groups) are oriented on the surface of the above alloy (especially iron alloy), and hydrophobic groups (alkyl groups) cover the surface of the above alloy. This is thought to result in a lubricating effect and smoother rotation of the ball, resulting in a better writing experience. (Structure of the Invention) Next, each component of the aqueous pigment ink of the present invention will be explained. The pigment is used as a coloring agent, and all conventionally known organic and inorganic pigments can be used, but specific examples include azo pigments, condensed polyazo pigments, phthalocyanine pigments, dioxazine pigments, and perinone.・Perylene pigments, quinacridone pigments, carbon black pigments, etc. can be used.
The amount used is 1 to 20% by weight based on the total amount of ink.
Preferably it is 3 to 10% by weight. As the dispersant, commonly used dispersants can be used, and specific examples include acrylic acid,
Examples include methacrylic acid resin emulsions, vinyl acetate resin emulsions, natural resin dispersants, and nonionic or anionic surfactants. As the solvent, in addition to water, water-soluble organic solvents used in dye-type water-based inks can be used; specific examples include glycol solvents, glycol ether solvents, and glycol ether ester solvents. , glycerin, and pyrrolidone. The amount of the ethylene oxide adduct of the alkyl-substituted phenol used is 0.1 to 4% by weight.
If it is less than 0.1% by weight, the effect is not clear, and if it is more than 10% by weight, the ink viscosity may become too high.
The dispersion system is destroyed and tends to aggregate. The alkyl group of the ethylene oxide adduct of this alkyl-substituted phenol has 5 to 20 carbon atoms, and specifically includes pentyl, isopentyl, neopentyl, hexyl, isohexyl,
-methylpentyl, 2,2-dimethylbutyl,
2,3-dimethylbutyl, heptyl, monomethylhexyl, dimethylpentyl, octyl, monomethylheptyl, dimethylhexyl, trimethylpentyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl,
There are straight chain and branched alkyl groups such as hexadecyl, heptadecyl, octadecyl, nonadecyl, eicosyl, etc. Also, the number of moles of ethylene oxide added is 5 to 50
It is a mole. In addition to the above-mentioned components, additives such as preservatives, surfactants for adjusting surface tension, dyes for complementary colors, etc. can be used as appropriate. Next, in the method for producing the water-based pigment ink of the present invention, the above-mentioned components are mixed, mixed, ground, and dispersed using a conventional dispersing machine such as a ball mill, roll mill, sand mill, super mill, dyno mill, attritor, etc. It can be obtained by (Example) Hereinafter, the present invention will be explained in more detail according to Examples, where "parts" in the examples indicate "parts by weight."
