Abstract

PURPOSE: To obtain a polyamide-imide resin excellent in heat resistance, coating properties and exconomy, by the reaction of a polyvalent carboxylic acid or its functional derivative, a polyvalent isocyanate or its functional derivative, and a monohydric alcohol in a solvent.
CONSTITUTION: A polyvalent carboxylic acid having at least one acid anhydride group in one molecule or its functional derivative, a polyvalent isocyanate having at least two isocyanate groups in one molecule or its functional derivative, and a monohydric alcohol having one hydroxy group in one molecule, and, if necessary, a polyvalent carboxylic acid having at least two carboxy groups in one molecule or its functional derivative, are reacted with each other in a solvent. The polyvalent carboxylic acid or its functional derivative is trimellitic anhydride, 1,2,3,4-butanetetracarboxylic acid, etc.
