Abstract | To provide an aqueous ink composition for a ball-point pen having a silicon carbide-based ball which enables formation of an aqueous ball-point pen that has a small coefficient of dynamic friction between a silicon carbide-based ball and a ball receiving seat and has smooth writing feeling, and has excellent writing feeling.SOLUTION: An aqueous ink composition for a ball-point pen having a silicon carbide-based ball contains a phosphate-based surface active agent which is represented by the following formula (I), and has an HLB of 6 or more and an acid value of 120 or more. In the formula, n is an integer of 0-20, R1 is an alkyl group having 1 or more carbon atoms, an aryl group having 6 or more carbon atoms or an unsaturated hydrocarbon group having 4 or more carbon atoms, R2 is M or -(CH2CH2O)n-R3, R3 is an alkyl group having 1 or more carbon atoms, an aryl group having 6 or more carbon atoms or an unsaturated hydrocarbon group having 4 or more carbon atoms, M is hydrogen, alkali metal, an ammonium group, an organic ammonium group or an organic amine group, and when M is two or more, each M may be different.SELECTED DRAWING: None
【課題】炭化ケイ素系ボールとボール受座との動摩擦係数が小さく書き味が滑らかであり、書き味の優れた水性ボールペンを形成し得る、炭化ケイ素系ボールを有するボールペン用水性インキ組成物の提供。【解決手段】下記式(I)で表され、HLB6以上、かつ、酸価120以上であるリン酸エステル系界面活性剤を含有する、炭化ケイ素系ボールを有するボールペン用の水性インキ組成物。(式中、nは0〜20の整数、R1は炭素数1以上のアルキル基、炭素数6以上のアリール基又は炭素数4以上の不飽和炭化水素基、R2はM又はー(CH2CH2O)nーR3、R3は炭素数1以上のアルキル基、炭素数6以上のアリール基又は炭素数4以上の不飽和炭化水素基、Mは水素、アルカリ金属、アンモニウム基、有機アンモニウム基又は有機アミン基、Mが2つある場合は各々異なってよい。)【選択図】なし |
