An aqueous dispersion of polymeric particles is provided to improve film integration(for example, scrub resistance) and to form films providing a high extent of white light scattering when film is dried. The aqueous dispersion comprises polymeric particles and has a BCOP hiding factor of at least 0.1. The polymeric particles include 10-80wt%, based on the total polymer weight of particles upon drying, of a first polymer comprising at least one void having a diameter of 100-1200nm upon drying, and at least one second polymer that contains at least one ethylenically unsaturated monomer as a polymerization unit, forms the film on the first polymer, and has a Tg of -60 to 50‹C. |
