Title:
POLYESTER RESIN, AND CAN COATING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2015/147145
Kind Code:
A1
Abstract:
An objective of the present invention is to provide a polyester resin from which a can coating material can be obtained, and a can coating material, which enable the formation of a coating film that has a restricted decrease in the workability thereof over time, maintains the basic functions of flavor resistance and retort resistance, and exhibits acid and alkali corrosion resistance, and advanced workability. Provided is a polyester resin that is obtained by reacting a polycarboxylic acid (A) and a polyol (B), wherein said polycarboxylic acid (A) contains, in a total 100 mol% thereof, 15-35 mol% of terephthalic acid, 55-80 mol% of isophthalic acid, and 1-18 mol% of at least one monomer selected from the group consisting of sebacic acid, adipic acid and 1,4-cyclohexanedicarboxylic acid, and wherein said polyol (B) contains, in a total 100 mol% thereof, 45-85 mol% of 1,4-butanediol.
