Beschreibung
Zusammenfassung:	The present invention relates to an aqueous pigment dispersion and an inkjet ink using the aqueous pigment dispersion, the aqueous pigment dispersion being characterized by containing a diacetoacetyl arylamine pigment (A), a dispersant (B), and an aqueous medium (C) and having an absorbance ratio represented by (absorbance at a wavelength of 408 nm)/(absorbance at a wavelength of 450 nm) of 1.40 or more. 本发明涉及一种水性颜料分散体、使用该水性颜料分散体的喷墨油墨，所述水性颜料分散体的特征在于，含有双乙酰乙酰芳胺颜料(A)、分散剂(B)、和水性介质(C)，由(波长408nm下的吸光度)/(波长450nm下的吸光度)表示的吸光度比为1.40以上。
