摘要 PROBLEM TO BE SOLVED: To provide an inkjet recording liquid in which aggregation of a colorant is prevented even when the inkjet recording liquid is locally dried at printer head nozzles, and whose jetting stability is excellent, in an ink including the colorant and a resin emulsion, and excellent in abrasion-resistance and lustrousness.SOLUTION: An inkjet recording liquid at least includes water, a water-soluble organic solvent, a colorant, and a resin emulsion, wherein the colorant includes a resin coating type coloring agent, and the resin emulsion is an anionic polyurethane resin emulsion, and a relation between an initial particle diameter (particle diameter D50(INI)) of particles included in a liquid composition and a particle diameter (D50(60%)) of particles included in the liquid composition which has been dried to a state having 60% by weight of the initial state satisfies following formula (1): 1.00&le;D50(60%)/D50(INI)<1.30.
