【発明の詳細な説明】
本発明は塗布及び筆記面のレベリング性に優れた水性顔
料インキに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water-based pigment ink with excellent application and leveling properties on a writing surface.
従来より、顔料と水とバインダーと界面活性剤とからな
る比較的高粘性の水性顔料インキは塗布或は筆記した際
、塗布及び筆記面のレベリング性(表面平滑性)が悪い
といった問題点を有していた。Conventionally, relatively high viscosity water-based pigment inks consisting of pigment, water, binder, and surfactant have had the problem of poor leveling (surface smoothness) of the application and writing surface when applied or written on. Was.
そこで本発明者は上記問題点を解決すべく。Therefore, the inventor of the present invention aimed to solve the above problems.
鋭意研究を重ねた結果、従来の水性顔料インキ組成に無
機コロイドを添加する事により、塗布及び筆記面の色む
らの少ないレベリング性に優れだ水性顔料インキが得ら
れることを見い出し本発明を完成したものである。As a result of extensive research, we discovered that by adding an inorganic colloid to a conventional water-based pigment ink composition, it was possible to obtain a water-based pigment ink with excellent leveling properties with less color unevenness on the application and writing surface, and thus completed the present invention. It is something.
即ち2本発明は、顔料と水とバインダーと界面活性剤と
無機コロイドとから少なくともなる水性顔料インキを要
旨とするものである。That is, the gist of the present invention is an aqueous pigment ink comprising at least a pigment, water, a binder, a surfactant, and an inorganic colloid.
本発明の水性顔料インキが何故塗布及び筆記面のレベリ
ング性に優れているのかは定かではないが以下の様に推
察する。It is not clear why the aqueous pigment ink of the present invention has excellent coating and writing surface leveling properties, but it is speculated as follows.
本発明の水性顔料インキは無機コロイドを添加している
ため、無機コロイド粒子が顔料表面に収着し顔料間に電
気化学的な反発力を与える為に顔料が一定間隙に均一に
配列し、レベリング性が向上するものと思われる。Since the aqueous pigment ink of the present invention contains an inorganic colloid, the inorganic colloid particles are adsorbed onto the pigment surface and provide electrochemical repulsion between the pigments, so that the pigments are uniformly arranged in a certain gap, resulting in leveling. It seems that the performance will improve.
