Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an aqueous recording liquid given by dispersing pigment therein, having satisfactory storage stability of the recording liquid, capable of satisfactorily preventing a nozzle from clogging, capable of giving satisfactory water resistance, weather resistance, and light resistance to printed matter, and capable of giving the printed matter blackness and a glossy feeling compartible with each other. SOLUTION: This aqueous recording liquid of a pigment dispersion contains at least the pigment and a resin, wherein the resin is contained in an amount of 50-200 pts.wt. based on 100 pts.wt. of the pigment, the resin contains a water-dispersible urethane-based resin, a polyurethaneurea part is contained in a weight ratio of ≤2.0 wt% in the urethane-based resin, and the pigment in the recording liquid has a dispersed particle diameter (D50) of 40-100 nm.
