Abstract:
1. An aqueous polymeric composition comprising: (a) polymeric nanoparticles, dispersed in an aqueous medium, said polymeric nanoparticles comprising, as polymerized units: said nanoparticles having a mean diameter in the range of from 1 to 10 nanometers and a glass transition temperature of at least 50° C.; and (b) second particles dispersed in said aqueous medium, said second particles being selected from the group consisting of second polymer particles and mixtures of second polymer particles and pigment particles, said second polymer particles having a glass transition temperature in the range of from −40° C. to 70° C.; wherein a total volume concentration of said pigment particles and said second polymer particles is at least 70%, based on total solids volume of said aqueous polymeric composition.
