Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an aqueous inkjet composition excellent in printing quality and printability.SOLUTION: Provided is an aqueous ink jet composition which is uniformly dispersed into an aqueous medium and has a coated organic pigment (C). The surface of the organic pigment (C) is coated with a water-insoluble resin (A) having an acid functional group such as a carboxyl group by a surfactant (B) having a betaine structure and an organic pigment derivative (D). 【課題】印字品質及び印字性に優れて水性インクジェット組成物を提供する。【解決手段】水性インクジェット組成物は、水性媒体中に均一に分散され、被覆された有機顔料（Ｃ）を有する。有機顔料（Ｃ）の表面は、ベタイン構造を有する界面活性剤（Ｂ）及び有機顔料誘導体（Ｄ）により、カルボキシル基などの酸官能基を有する水不溶性樹脂（Ａ）で被覆されている。【選択図】なし
