Abstract

The instant invention is a composite dispersion, method of producing the same, and articles made therefrom. The composite dispersion according to the instant invention comprises (1) a first seed dispersion comprising (a) a first internal phase; and (b) an external phase, and (2) a second internal phase; wherein the composite dispersion comprises more than 60 percent by the combined weight of the first internal phase and the second internal phase, and the composite dispersion has a viscosity of less than 10,000 cP measured by RV4 spindle at 20 rpm at greater than 60 weight percent total internal phase, and wherein the composite dispersion has a bimodal particle size distribution and a particle size ratio (P2/P1) in the range of 2 to 200.
