  • Patent number: 4332701
    Abstract: There are disclosed thermosettable polyester resins which are the reaction products of specified amounts of a benzenedicarboxylic acid component (e.g.: 1,3-benzenedicarboxylic acid), a trihydroxy alkyl component (e.g.: 2-ethyl-2-(hydroxymethyl)-1,3-propanediol), a short chain alkylene diol component having four or fewer carbon atoms in the primary carbon chain between the hydroxyl moieties (e.g.: 2,2-dimethyl-1,3-propanediol), a dihydroxy alkyl constituent having four to ten carbon atoms in the primary carbon chain between the hydroxyl moieties (e.g.: 1,6-hexanediol), and a monocarboxylic acid component (e.g.: benzoic acid). Such polyesters, having a number average molecular weight of from about 400 to about 1600 and a combined acid and hydroxyl number of about 50 to about 250 milligrams of KOH per gram of polyester, are found to be especially useful in high solids content coating formulations.
