Abstract
An aqueous dispersion of polymeric particles and process for forming thereof is provided. The particles comprise a first polymer comprising, as polymerized units, at least one monoethylenically unsaturated monomer and at least one multi-ethylenically unsaturated monomer and when dry, at least one void; and at least one second polymer, substantially encapsulating the first polymer, comprising, as polymerized units, at least one ethylenically unsaturated monomer.
