Abstract:
An aqueous dispersion comprising: water; a hydrophobic aromatic polyester having a number average molecular weight of greater than 7,000 Daltons; and a water-dispersible aromatic polyester dispersant; wherein the hydrophobic aromatic polyester and the water-dispersible aromatic polyester dispersant form a stable aqueous dispersion; and wherein the hydrophobic aromatic polyester is present in the aqueous dispersion in an amount of less than 50 wt-%, based on the total weight of the hydrophobic aromatic polyester and the water-dispersible aromatic polyester dispersant.
