A coating composition comprising nitrocellulose; a copolymer of ethylene and an ethylenically unsaturated ester of a saturated fatty acid, said copolymer comprising between about 40% and about 90% by weight of said ester, said copolymer characterized by a kinematic viscosity at 140.degree. C. of up to about 30,000 centipoise, said copolymer present in an amount of more than about 25% to about 60% by weight, based on the total weight of said nitrocellulose and said copolymer; and an organic solvent system for said nitrocellulose and said copolymer is disclosed.

Coating composition

A coating composition of enhanced physical characteristics such as those of hardness, flexibility and/or ultra-violet resistance is provided which comprises a mixture of ethylene-vinyl ester copolymer containing at least about 55% by weight of interpolymerized vinyl ester and a dibasic acid-modified rosin ester of a rosin acid and a polyhydric alcohol containing from 2 to 6 hydroxyl groups, said dibasic acid-modified rosin ester being present in said composition at a level of at least about 30% by weight.

Ethylene-vinyl ester copolymer blended with dibasic acid-modified rosin

Sulfur dioxide-ethylene-vinyl ester terpolymers exhibiting improved thermal stability are prepared by substantially uniformly incorporating therein a thermal stability-imparting amount of at least one inorganic oxygen-containing metal compound in which the metal is an alkali metal, alkaline earth metal or zinc.
