20250346779 · 2025-11-13 ·

Provided is an aqueous coating composition that can exhibit high coating film performance even when cured at a relatively low temperature. The present invention pertains to an aqueous coating composition comprising (A) a hydroxyl group-containing resin and (B) a blocked polyisocyanate compound. The weight average molecular weight of the blocked polyisocyanate compound (B) is in a range of 20,000-200,000.
