Title (EN) WATER-BASED INK COMPOSITION FOR BALLPOINT PEN
(FR) COMPOSITION D'ENCRE À BASE D'EAU POUR STYLO À BILLE
(JA) 水性ボールペン用インク組成物
Abstract:
(EN) Provided is a water-based ink composition for a ballpoint pen, the ink composition having exceptional ink discharge properties when starting writing (writing-start properties) even if the nib is exposed for an extended period of time. The water-based ink composition for a ballpoint pen is characterized by: being constituted by (a) a polyoxyalkylene alkyl ether unit represented by formula (I), (b) a maleic anhydride unit, and (c) a styrene unit; the composition ratio of these units being (a):(b):(c) = 25-75:25-75:0-50; and containing at least 0.1-5 mass% of a grafted product of an allyl alcohol/maleic anhydride/styrene copolymer having a mass average molecular weight of 1000-50,000 and a polyoxyalkylene monoalkyl alcohol, 5-40 mass% of resin particles, and water. (In formula (I), R represents a C1-5 alkyl group, and m is a positive integer from 5-50.)
(FR) L'invention concerne une composition d'encre à base d'eau pour stylo à bille, la composition d'encre ayant des propriétés exceptionnelles d'éjection de l'encre lors du démarrage de l'écriture (propriétés au démarrage de l'écriture) même si la pointe est exposée pendant une période de temps prolongée. La composition d'encre à base d'eau pour stylo à bille se caractérise en ce qu'elle est constituée par (a) un motif éther alkylique de polyoxyalkylène représentée par la formule (I), (b) un motif anhydride maléique et (c) un motif styrène ; en ce que le rapport de composition de ces unités est (a)/(b)/(c) = 25-75/25-75/0-50 ; et en qu'elle contient au moins 0,1-5 % en masse d'un produit greffé d'un copolymère d'alcool allylique/anhydride maléique/styrène ayant un poids moléculaire moyen en masse compris entre 1000 et 50 000 et d'un alcool monoalkylique de polyoxyalkylène, de 5 à 40 % en masse de particules de résine et de l'eau. (Dans la formule (I), R représente un groupe alkyle en C1-5, et m est un nombre entier positif compris entre 5 et 50.)
(JA) 長期間に亘ってペン先を露出させても書き初めのインク吐出性(初筆性)に優れた水性ボールペン用インク組成物を提供する。 水性ボールペン用インク組成物は、(a)下記式(I)で表されるポリオキシアルキレンアルキルエーテル単位、(b)無水マレイン酸単位、(c)スチレン単位で構成され、これらの組成比がモル%で(a):(b):(c)=25~75:25~75:0~50であり、かつ質量平均分子量が1000~50000であるアリルアルコール・無水マレイン酸・スチレン共重合物とポリオキシアルキレンモノアルキルアルコールとのグラフト化物0.1~5質量%と、樹脂粒子5~40質量%と、水とを少なくとも含有することを特徴とする。 〔上記式(I)中、Rは炭素数1~5のアルキル基を示し、mは5~50の正の数である。〕
