| 摘要 |
Novel linear polyesters suitable for the preparation of thermoset coatings having improved flexibility and hardness are disclosed. The linear polyesters, comprised of recurring units of 2-methyl-1,3-propanediol and at least one cyclic dicarboxylic acid moiety, are used in thermosettable resin compositions additionally containing an aminoplast cross-linking agent and a catalyst. Pigment and solvent may optionally also be present in such compositions.
