MODIFIED COPOLYMER POLYESTER RESIN AND AQUEOUS DISPERSION THEREOF
[Problem] The present invention aims to provide a high-molecular-weight modified copolymerized polyester resin that has a reactive functional group at a site other than the terminals of the molecular chain thereof, has an excellent reactivity with a curing agent (such as an epoxy resin or an isocyan...

| description | [Problem] The present invention aims to provide a high-molecular-weight modified copolymerized polyester resin that has a reactive functional group at a site other than the terminals of the molecular chain thereof, has an excellent reactivity with a curing agent (such as an epoxy resin or an isocyanate compound), and can be used to form an organic-solvent-and-emulsifier-free water dispersion having excellent storage stability.[Solution] A modified copolymerized polyester resin (B) having a structure in which a copolymerized polyester resin (A) has an unsaturated polyvalent carboxylic acid added to a side chain thereof, and the copolymerized polyester resin (A) contains, as copolymerization components, at least one member selected from the group consisting of : a copolymerization component having an alicyclic structure (component x); a copolymerization component having six or more continuous methylene groups (component y); and an acyclic aliphatic copolymerization component having a tertiary carbon atom and a molecular weight of more than 100 (component z). |
