| abstract |
The present invention relates to a resin composition comprising a resin α1 and a resin α2, wherein the resin α1 includes an aromatic dicarboxylic acid monomer unit A1 having a hydrophilic group, and a dicarboxylic acid monomer unit having no hydrophilic group. Body unit B1, and aromatic monomer unit C1, the above-mentioned resin α2 has an aromatic dicarboxylic acid monomer unit A2 having a hydrophilic group, a dicarboxylic acid monomer unit B2 not having a hydrophilic group, and In the aliphatic monomer unit C2, the resin α2 contains monomer units other than the monomer units constituting the resin α1, and the mass ratio of the content of the resin α1 to the content of the resin α2 is 0.9 or more and 20 or less. According to the present invention, it is possible to provide a resin composition that can be easily removed with only water while maintaining the heat resistance of the polymer. |
