Some dispersions include less than about 4 percent by weight of the dispersing agent based on the weight of the thermoplastic resin. Other dispersions include at least one propylene-rich alpha-olefin interpolymer; at least one dispersing agent; and water. Methods of making such dispersions are also described.

Claims (2)

1. An aqueous dispersion consisting essentially of (A) from 35 to 65 percent by weight of one or more polyesters; and (B) optionally one or more dispersing agents and (C) at least 30% by weight of water; wherein the dispersion has a pH in the range of from 6 to 9, a volume average particle size diameter in the range of from 0.05 to 5 μm.

2. The dispersion according to claim 1 , wherein the dispersion has a volume average particle size in the range of from 0.05 to 0.5 μm.
