Estimating the term…
A coating composition containing a polyester resin (A) having an acid value of not lower than 5 mgKOH/g, a polyester resin (B) having an acid value of lower than 5 mgKOH/g, and a curing agent having a functional group capable of crosslinking reaction with a carboxyl group. Assuming that the total solid content mass of the polyester resin (A) and the polyester resin (B) is 100 parts by mass, the content of the polyester resin (A) is in a range of more than 50 parts by mass to not more than 97 parts by mass, and the content of the polyester resin (B) is in a range of not less than 3 parts by mass to less than 50 parts by mass. Also disclosed is a coated metal substrate and a drawn-ironed can formed of the coated metal substrate.
