Patent attributes
An aqueous dispersion of polymeric particles, the particles including: from 5% to 80% by weight, based on the weight of the polymeric particles, of a first polymer including at least one copolymerized ethylenically unsaturated monomer; and, substantially encapsulating the first polymer, from 20% to 95% by weight, based on the weight of the polymeric particles, of a second polymer including at least one copolymerized ethylenically unsaturated monomer, the second polymer having a Tg of from −40° C. to 30° C., wherein at least 90 weight % of the second polymer is formed by polymerization at a temperature of from 5° C. to 65° C. is provided. The invention also relates to a process for forming the aqueous dispersion of polymeric particles and an aqueous coating composition including the aqueous dispersion of polymer particles, a method for providing a coated substrate, and the coated substrate so provided.
