| 1. A composition, comprising:
a polyester;
an aromatic epoxy compound, in an amount sufficient to provide 5 to 300 milliequivalents of epoxy per kilogram of polyester;
and
from 0.5 to 6 weight percent, based on the weight of the polyester,
an epoxy-functional polyolefin; and
a copolyester copolymer, wherein the copolyester comprises, based on the weight of the copolyester,
15 to 95 weight percent of polyester units derived from the reaction of a C6-C24 aromatic dicarboxylic acid or a chemical
equivalent thereof with a C2-C6 aliphatic diol, and
5 to 85 weight percent of polyester units derived from the reaction of a C6-C24 aromatic dicarboxylic acid or a chemical equivalent
thereof with a poly(alkylene oxide) glycol having a molecular weight of 400 to 6,000 and a carbon to oxygen ratio from 2.0
to 4.3.
