Japanese Patent JP6753039
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a polyester resin suitable for a can coating resin composition from which such a coating film can be formed that excels in anti-contamination property on a content and in alkali resistance and substantially prevents decrease in processability with time, and a can coating resin composition.SOLUTION: A polyester resin is obtained by reacting a polycarboxylic acid (A) and a polyol (B). The polycarboxylic acid (A) in total 100 mol% comprises 15 to 40 mol% of terephthalic acids and 50 to 85 mol% of isophthalic acids. And the polyol (B) in total 100 mol% comprises 10 to 45 mol% of an alicyclic diol, 40 to 80 mol% of a linear diol (a) having 4 to 6 carbon atoms and having a primary hydroxyl group at both ends and no side chain, and 5 to 35 mol% of a diol (b) having 3 to 4 carbon atoms and having one primary hydroxyl group and one secondary hydroxyl group.SELECTED DRAWING: None
