Abstract

A polyester resin for metal plate coating which contains a dimer acid in an amount of 2 to 10 mol %, as a dicarboxylic acid component and has a weight average molecular weight (Mw) ranging from 70,000 to 160,000. Thus, there can be provided a polyester resin for metal plate coating that has not only excellent film forming capability and corrosion resistance but also excellent impact resistance. Further, there can be provided a resin-coated metal plate excelling in properties, such as corrosion resistance, impact resistance (dent resistance), workability and flavor, and provided, fabricated from the resin-coated metal plate, a metal can and can lid.
