Abstract
PURPOSE:To prepare the title resin having excellent pigment-dispersing capability, processability, coating film hardness and stain resistance, by polycondensation of a specific polyester resin with a polyalkylene glycol. CONSTITUTION:1 equivalent of an acid component composed of 100-40mol.% (hereinafter merely '%') arom. dicarboxylic acid component, 0-60% aliph. dicarboxylic acid component, 0-5% monocarboxylic acid component and 0-5% at least tribasic polycarboxylic acid component is reacted with 1-1.3 equivalents of an alcohol component composed of 100-95% dialcohol component and 0-5% at least trihydric polyhydric alcohol component at 160-260 deg.C to prepare a polyester resin (A) having an acid value of at most 3. 95-99.5wt.% component A is polycondensed with a polyalkylene glycol (B) having an MW of 2,000-10,000 in the presence of a catalyst (e.g., Sb2O3) under a reduced pressure of at most 10mmHg at 200-300 deg.C to prepare a polyalkylene glycol-modified polyester resin having an No.-average MW of at least 10,000.
