一般に水を主成分とする液媒体中に顔料を分散してなる水性顔料分散液は、顔料、水、有機溶剤、樹脂、アルカリ剤などを配合して分散機を用いて分散処理を行うのが一般的である。特にインクジェット記録用顔料インクを製造するための水性顔料分散液は、水溶性高分子化合物、界面活性剤などの分散剤を用いて顔料を水に分散して調製される。調製された水性顔料分散液は、保存安定性、吐出安定性などを確保するため、高度な凝集安定性や沈降安定性が要求される。顔料インクの凝集安定性や沈降安定性は、ほぼ使用する分散剤の性能により決定される。これまでにノニオン、アニオン型界面活性剤、親水性ブロックと疎水性ブロックを有するブロック共重合体、樹脂粒子を含有する樹脂エマルションなどの様々な分散剤が試みられてきた（例えば、特許文献１〜３参照）。しかしながら、従来の分散剤では、インクジェット記録用顔料インクとして適正な粘度にすると再分散性に乏しく、凝集安定性や沈降安定性を十分に確保することが困難となり、インクジェットノズルの目詰まりが生じ吐出安定性が悪いものであった。また、分散剤濃度を増して顔料インクの凝集安定性や沈降安定性を確保するとインク粘度が上昇する、サーマルヘッドの場合焦げ付きが発生するなどの問題が起こり、インクの安定性とインクとしての性能を両立させることが困難であった。
本発明が解決しようとする課題は、初期分散性、長期保存安定性に優れた水性インク又は水性塗料を得ることであり、特にインクジェット記録用顔料インクの吐出安定性を改善しノズルの目詰まりを防止することである。 The problem to be solved by the present invention is to obtain a water-based ink or water-based paint excellent in initial dispersibility and long-term storage stability.

This is a product obtained by reacting a saturated or unsaturated fatty acid or aromatic carboxylic acid, and a dispersant having an HLB in the range of 12 to 19 is blended in an amount of 0.01 to 70% by weight based on the pigment. As a result, the above problems have been solved, and it has been found that the initial dispersibility, long-term storage stability, and ejection stability of the pigment ink for inkjet recording have been dramatically improved, and the present invention has been achieved.
本発明の顔料分散剤を添加することにより、初期分散性、長期保存安定性に優れた水性顔料インク又は塗料が得られる。また、本発明によれば、特に初期分散性、長期保存安定性、吐出特性、印字特性に優れたインクジェット記録用顔料インクが得られる。 By adding the pigment dispersant of the present invention, an aqueous pigment ink or paint excellent in initial dispersibility and long-term storage stability can be obtained.
