CATIONIC ELECTRODEPOSITION COATING AND METHOD FOR CONTROLLING GLOSS LEVEL OF ELECTRODEPOSITION COATING FILM

摘要

PROBLEM TO BE SOLVED: To provide a cationic electrodeposition coating capable of forming low-gloss electrodeposition coating film of good smoothness and enabling the low-gloss level to be sustained for a long period, and to provide a method for controlling the gloss level of the electrodeposition coating film. SOLUTION: The cationic electrodeposition coating comprises colloidal metallic bismuth and a resin composition having both sulfonium and propargyl groups and also a polymeric pigment dispersant.
