Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a naphthol red having excellent dispersibility and coloring by controlling the particle shape, and to provide a resin composition, an aqueous dispersion and a solvent dispersion that are colored with the naphthol red, and a manufacturing method.SOLUTION: A naphthol red includes primary particles having an axial ratio (average major axis diameter/average minor axis diameter) of 1.0-2.0. Also provided are a resin composition, an aqueous dispersion and a solvent dispersion that contain the naphthol red, and a manufacturing method.SELECTED DRAWING: None 【課題】本発明に係るナフトールレッドは、粒子形状を制御することにより、分散性に優れ、発色性に優れたナフトールレッドを提供するものである。ならびに該ナフトールレッドによって着色した樹脂組成物、水系分散体、溶剤系分散体、および、製造方法を提供するものである。【解決手段】一次粒子の軸比（平均長軸径／平均短軸径）が１．０〜２．０の範囲であるナフトールレッドであり、当該ナフトールレッドを含有する樹脂組成物、水系分散体、溶剤系分散体、または、製造方法である。【選択図】なし
