COPOLYMERIZED POLYESTER RESIN, METHOD FOR PRODUCING SAME, AND RESIN COMPOSITION CONTAINING COPOLYMERIZED POLYESTER RESIN

WIPO Patent Application WO/2006/095901

A1

Disclosed is a copolymerized polyester resin obtained without using a conventional catalyst such as an antimony compound. Also disclosed are a resin composition containing such a copolymerized polyester resin, a coating material using such a resin composition, a toner, a binder resin, a coated metal plate, a hot melt adhesive and an extrusion coating material. Specifically disclosed is a copolymerized polyester resin produced in the presence of a catalyst containing at least an aluminum compound. This copolymerized polyester resin is characterized in that the polyvalent carboxylic acid component constituting the copolymerized polyester resin contains not less than 20% by mole of an aromatic dicarboxylic acid, and the polyhydric alcohol component constituting the copolymerized polyester resin contains at least one alcohol selected from ethylene glycol, diethylene glycol, 1,3-propanediol, 1,4-butanediol, 2-methyl-1,3-propanediol, alkylene glycols having 5-10 carbon atoms, 1,4-cyclohexanedimethanol and polyhydric alcohols having specific structures.
