【Task】 Dispersion with excellent non-aggregability, fluidity and storage stability suitable for fields such as paints and colored resin compositions can be produced, and at the same time, dispersion with excellent chemical resistance, solvent resistance and heat resistance Manufacturing the body. [Solution] A carboxyl group obtained by reacting an acid anhydride group in one or more acid anhydrides selected from tetracarboxylic acid anhydride (a) and tricarboxylic acid anhydride (b) with a hydroxyl group in the hydroxyl group-containing compound (c) One or more ethylenically unsaturated monomer radicals selected from a polyester portion A having a hydroxyl group, an ethylenically unsaturated monomer having no hydroxyl group (e), and an ethylenically unsaturated monomer having a hydroxyl group (f) A curable dispersant comprising a polymerized vinyl polymer portion B, wherein the vinyl polymer portion B has a (meth) acryloyl group.
