Abstract

PURPOSE: To produce titled resin which provides paints having good melt-coatability and bakability, by reacting a dicarboxylic acid with a diol and a triol, and thereafter reacting the product with an imide acid-forming component.
CONSTITUTION: (a) Twenty-thirty (20W30)eq.% of a dicarboxylic acid component selected from terephthalic acid (lower alkyl ester) and isophthalic acid (lower alkyl ester), (b) 44W55eq.% of a diol such as ethylene glycol and 14W 20eq.% of a triol such as glycerin are precondensed at 180W200°C for 8W10hr in the absence of a solvent. Then, the temperature of the reaction product is lowered to below 150°C. To this reaction product is added (d) an imide acid-forming component comprising 1mol of a diamine and 2mol of a tricarboxylic acid (anhydride) having two vicinal carboxyl groups, in an amount to provide 5W10eq.% of imide acid, 25W40wt% based on the total composition, of component (d) and a total alcohol/total acid eq. ratio of 1.7W2.2. Then, the resulting mixture is reacted by heating.
