ABSTRACT:
Disclosed are compositions comprising a polyester derived from 100 mole % of an acid component and 100 mole % of a glycol component, the acid component comprising about 30-90 mole % of at least one .alpha.,.beta.-ethylenically unsaturated dicarboxylic acid and about 70-10 mole % of a compound containing a cinnamic acid moiety, and the glycol component comprising at least one saturated aliphatic glycol containing from 2 to 10 carbon atoms. These compositions have improved resistance to attack by organic solvents.
