ANIONIC ELECTRODEPOSITION COATING COMPOSITION, METHOD FOR ANIONIC ELECTRODEPOSITION COATING AND COATED PRODUCT OBTAINED THEREFROM

摘要

PROBLEM TO BE SOLVED: To provide an anionic electrodeposition coating composition having good storage stability and high anticorrosion properties and environmental compatibility, a method for anionic electrodeposition coating and a coated product obtained from the method.;SOLUTION: This anionic electrodeposition coating composition is characterized as comprising a resin composition having carboxylic acid groups and propargyl groups. The resin composition preferably further has hydroxy groups. The contents of the carboxylic acid groups and the propargyl groups contained therein are 5-400 mmol of the carboxylic acid groups and 10-495 mmol of the propargyl groups based on 100 g of solids in the resin composition. The total content of the carboxylic acid groups and the propargyl groups is preferably ≤500 mmol.;COPYRIGHT: (C)2002,JPO
