ELECTRODEPOSITION COATING MADE FROM ANIONIC ACRYLIC COPOLYMER

摘要

PROBLEM TO BE SOLVED: To provide an electrodeposition coating which saves energy for curing thereof by lowering a curing temperature thereof. SOLUTION: An electrodeposition coating is obtained by dispersing a neutralized compound of an anionic acrylic copolymer having carboxylic groups and oxazoline groups in water. An acid value of the anionic acrylic copolymer is preferably 30-160 mg-KOH/g-resin and a molar ratio of the carboxylic groups to the oxazoline groups is preferably 1/10-10/1. The curing temperature of the electrodeposition film is 120-160 deg.C.
