Abstract
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.
