Abstract
The present disclosure is a cationic electrodeposition coating composition comprising an emulsion particle (A) containing a Michael addition reaction donor component and an emulsion particle (B) containing a Michael addition reaction acceptor component wherein a Michael addition reaction catalyst (C) is contained in the emulsion particle (A) or the emulsion particle (B) or is contained in the cationic electrodeposition coating composition by being microencapsulated.
Claims15
A cationic electrodeposition coating composition comprising:
- a first emulsion particle (A) containing a Michael addition reaction donor component and a second emulsion particle (B) containing a Michael addition reaction acceptor component,
- wherein the Michael addition reaction donor component is an active hydrogen group-containing compound whose skeleton is a resin,
- wherein the first emulsion particle (A) and the second emulsion particle (B) are present separately in the cationic electrodeposition coating composition, and
- wherein a Michael addition reaction catalyst (C) is contained in the first emulsion particle (A) or the second emulsion particle (B) or is contained in the cationic electrodeposition coating composition by being microencapsulated.
