Abstract
A dispersion liquid includes water, a coloring material, a dispersion resin that disperses the coloring material, and a compound having s sulfonate group and a polymerizable group. The dispersion resin has a constituent unit A containing a hydrophobic monomer and a constituent unit B containing a monomer having a sulfonate group. The weight-average molecular weight of the dispersion resin is 5,000 to 100,000, and the molecular weight of the compound is 300 or less.
