Abstract
Linear polyester diols suitable for the preparation of thermoset coatings having improved flexibility and hardness are disclosed. The linear polyesters consist essentially of recurring units of isophthalic acid, an aliphatic diol component including 2-methyl-1,3-propanediol, and optionally, a dicarboxylic acid other than isophthalic acid. The linear polyester diols are useful for thermosettable resin compositions that comprise the polyester diol, an aminoplast crosslinking agent, and a catalyst.
