Abstract
A composition including: (a) at least one anionically stabilized acrylic polymer dispersion where the acrylic polymer contains acid monomer units; and (b) at least on polyamino siloxane relative to the weight of the total polymers in the composition, wherein the polyaminosiloxane copolymer containing steric stabilizing groups having a pendant group with a secondary or a primary amine functionality; and (ii) at least a portion of the silicon atoms in the polyaminosiloxane copolymer containing steric stabilizing groups having a pendant alkyl-poly(ethylene oxide) chain with 5 ethylene oxide units to 20 ethylene oxide units.

A stable waterborne composition comprising:
- (a) at least one anionically stabilized acrylic polymer dispersion, wherein the acrylic polymer contains at least a portion of polymerized acid monomer units;
- and
- (b) at least one polyaminosiloxane copolymer-containing steric stabilizing groups, wherein (i) at least a portion of the silicon atoms in the polyaminosiloxane copolymer contain a pendant group with a secondary or a primary amine functionality;
- and (ii) at least a portion of the silicon atoms in the polyaminosiloxane copolymer-containing steric stabilizing groups have a pendant alkyl-poly(alkylene oxide) chain,
- wherein the portion of the polymerized acid monomer units in the acrylic polymer is from 0.1 weight-percent of more to 5.0 weight-percent of less based on the total weight of all monomers in the polymer;
- wherein the portion of the silicon atoms in the polyaminosiloxane copolymer containing a pendant group with a secondary or a primary amine functionality is from 60 mol % or more to 97 mol % or less based on the total of the polyaminosiloxane copolymer;
- and wherein the portion of the silicon atoms in the polyaminosiloxane copolymer-containing steric stabilizing groups having a pendant alkyl-poly(alkylene oxide) chain is from 3 mol % or more to 17 mol % or less based on the total of the polyaminosiloxane copolymer.
