題が発生する。従ってこのタイプの水性インキは特定の
機構の筆記具または記録計にしか適用できない。Problems to be Solved by the Invention Inks that use pigments as colorants do not have sufficient dispersion stability in low viscosity vehicles, and over time, the pigments settle and form in the capillary tubes of the pen nibs of writing instruments and recorders. Roads are often blocked. On the other hand, if the viscosity of the vehicle is increased to improve dispersion stability, a problem arises in that it impairs the ink flow in writing instruments and recorders that use capillary tubes as ink passages. Or it can only be applied to recorders.

作用
本発明の水性インキでは前記部分スルホン化ポリエステ
ル樹脂自体はスルホン酸基及びグリコール部の作用によ
り、分散または溶解状態で水中に安定に存在する。そし
てポリマーの主体成分である疎水性部分に疎水性染料が
会合した状態で含まれる。従って染料は前記樹脂を含有
する水性ビヒクル中に高濃度に配合される。Function: In the aqueous ink of the present invention, the partially sulfonated polyester resin itself stably exists in water in a dispersed or dissolved state due to the action of the sulfonic acid groups and glycol moieties. The hydrophobic dye is contained in a state associated with the hydrophobic portion which is the main component of the polymer. The dye is therefore incorporated in high concentrations into the aqueous vehicle containing the resin.
この水性インキにより紙、フィルム等の対象表面に形成
される筆跡または記録は部分スルホン化ポリエステル樹
脂が表面に固着し、該樹脂中に染料が含有されており、
その上染料自体が実質的に水に不溶であるので、完全な
耐水性を示す。The handwriting or record formed on the target surface of paper, film, etc. with this water-based ink is caused by a partially sulfonated polyester resin that adheres to the surface, and the resin contains a dye.
Moreover, since the dye itself is virtually insoluble in water, it exhibits complete water resistance.

表−２試験の結果
発明の効果
表２に示された結果のとおり、比較例インキでは筆跡は
用いられる染料によっては耐水性であるが、完全でない
ものもある。紙への滲み、裏抜けも部分的に認められる
。その上筆記中に溶剤（トルエン）臭が感じられ、油性
インキの欠点が完全には解消されていない。Table 2 Results of Test Effects of the Invention As shown in Table 2, the handwriting of the comparative inks is water resistant depending on the dye used, but some are not completely water resistant. Bleeding and bleed through to the paper are also partially observed. Moreover, the odor of the solvent (toluene) can be felt while writing, and the drawbacks of oil-based inks have not been completely eliminated.
これに対し、本発明の水性インキによる筆跡は色種にか
かわらず完全に耐水性であり、紙への滲み、裏抜は現象
はみられない。当然のことながら筆記中に臭気が感じら
れる事もない。On the other hand, the handwriting made with the water-based ink of the present invention is completely water-resistant regardless of the color type, and there is no phenomenon of bleeding or bleed-through on paper. Naturally, you won't notice any odor while writing.
