摘要： 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.

摘要： A dispersion of the present disclosure includes a polyester functioning as a dispersant, water, and a dispersoid, and the polyester includes, as a monomer component, a first monomer having an aromatic ring on a side chain and a second monomer having at least one selected from the group consisting of a carboxy group which forms no ester bond and a sulfo group. A content of the first monomer with respect to all monomers forming the polyester is preferably 25 to 75 percent by mole.

摘要： A dispersant-containing liquid of the present disclosure contains anionic water-soluble polyester containing a carboxylate and/or a sulfonate, polyalkylene glycols, and water. When a content of the water-soluble polyester in the dispersant-containing liquid is defined as XPEs [mass %] and a content of the polyalkylene glycols in the dispersant-containing liquid is defined as XPAG [mass %], it is preferable that Expression (4) be satisfied.
