Disclosed is an alkyd composition adapted to be dissolved in a solvent and used as a high solids coating, said alkyd composition being derived from the following components:

Alkyd composition for high solids coatings

Disclosed are crystalline polyesters having low melt viscosities, and thermosetting compositions comprising these polyesters. The compositions are especially useful as powder coatings. At least 40 mole percent of the acid moiety is a terephthalic or isophthalic acid moiety, and the polyester contains as moieties of the dihydric alcohol about 40-100 mole percent 1,6-hexanediol, the polyester being further characterized as having a molecular weight of about 700-3000, a melt viscosity of about 50-3000 cps at 160.degree. C. and a hydroxyl number of about 30-160.
