AQUEOUS COATING COMPOSITION AND METHOD FOR PRODUCING COATED METAL SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2018/207891
Kind Code:
A1
Abstract:
The present invention relates to a polyester-based aqueous coating composition which is suitably applicable to metal covers or metal containers for beverage cans and the like. This polyester-based aqueous coating composition is configured to contain a polyester resin which has an acid value of 5 mgKOH/g or more but less than 30 mgKOH/g and a curing agent which has a functional group that is reactive with a carboxyl group of the polyester resin. Consequently, this polyester-based aqueous coating composition is able to form a coating film that has excellent processability, curability and corrosion resistance.
