Abstract:
A dispersion liquid includes water, a coloring material, and a dispersion resin that disperses the coloring material. The dispersion resin has a constituent unit A containing a hydrophobic monomer, a constituent unit B containing a hydrophilic acrylic acid monomer, and a constituent unit C containing a hydrophilic vinyl monomer having a sulfonate group, and the weight-average molecular weight of the dispersion resin is 10,000 to 100,000. The content of the constituent unit A is 60 mol % or more relative to the total amount of the dispersion resin.
