Abstract: Polyester resin compositions that are desirable for use in solvent-borne metal packaging and coil coating applications, the composition comprising: (a) a polyester comprising residues of: (i) terephthalic acid and isophthalic acid; and (ii) a blend of at least two glycols; wherein the amount of terephthalic acid is 15 mole percent to 20 mole percent and the amount of isophthalic acid is 80 to 85 mole percent wherein the total amount of terephthalic acid and isophthalic acid in the resin equals 100 mole percent; and (b) a non-aqueous solvent; wherein the composition remains clear at a temperature of 20-30° C. for at least 120 days.

Abstract: Disclosed are polyester resins containing phthalic acids in combination with glycols. The polyester resins are desirable for use in coatings for solvent-borne metal packaging and coil coating applications. Compositions composed of the disclosed polyester resins and non-aqueous solvents remain clear upon visual observation after storage at a temperature of 20-30° C. for at least 120 days.
