Document Type and Number:
WIPO Patent Application WO/2016/088828
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a naphthol red having excellent dispersibility and color development by controlling 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. Said purpose is achieved by means of: a naphthol red in which the primary particles have an axial ratio (average major axis diameter/average minor axis diameter) of 1.0–2.0, or a naphthol red represented by chemical formula (11) in which 0.01–0.3 wt% of a hydrophilic naphthol derivative represented by chemical formula (4) or a hydrophilic phenol derivative represented by chemical formula (5) is surface treated; a resin composition, an aqueous dispersion, and a solvent dispersion that contain the naphthol red; and a manufacturing method.
