Abstract:
1. A composition comprising an aqueous dispersion of: a) a film-forming polymer having a volume average diameter in the range of from 50 nm to 300 nm; b) spherical polymer beads having a volume average diameter in the range of from 0.8 μm to 20 μm; and c) a HASE rheology modifier having a backbone with pendant alkylated ethoxylate groups, wherein the alkylated portion of the alkylated ethoxylate groups has a Hansch parameter in the range of from 4 to 7.5; the weight-to-weight ratio of the spherical beads to the film-forming polymer is in the range of from 90:10 to 10:90; the weight-to-weight ratio of the HASE rheology modifier to the film-forming polymer is in the range of 2 to 25; and the concentration of pendant alkylated ethoxylate groups is from 1 to 20 weight percent, based on the solid weight of the HASE rheology modifier.
