Abstract: The present invention is a water-dispersible resin composition containing: a resin α that includes, in the main chain thereof, a structure M having two aromatic rings linked by a sulfide group, a sulfonyl group, an imide group, or a keto group; and a resin β having a hydrophilic group, the resins α and β being configured to form a co-continuous structure including three-dimensional continuous phases of the resins α and β. The present invention can provide a water-dispersible resin composition that maintains the heat resistance of the polymer material and can be removed only with water.

Abstract: A composite material includes a resin α including an aromatic dicarboxylic acid monomer unit A having a hydrophilic group and a dicarboxylic acid monomer unit B having no hydrophilic group, a resin β that is a different from resin α, and metal compound particles γ. A content of the metal compound particles γ may be 50 to 500 parts by mass with respect to 100 parts by mass of the resin α and the resin β together. A weight average molecular weight of the resin α may be 5,000 to 50,000. A content of the resin β may be 1 to 500 parts by mass or less with respect to 100 parts by mass of the resin α.
