Patent ID: 7612126

Claim:
An aqueous coating composition, comprising a multi-stage polymer dispersion comprising a) an inner phase comprising at least one latex polymer derived from at least one monomer and at least one polymerizable alkoxylated surfactant having the structure: R 1 —R 2 wherein R 1 is an allyl group selected from the group consisting of CH 3 —CH═CH— and CH 2 ═CH—CH 2 —, or an acrylic group and R 2 is a radical comprising at least two carbon atoms and at least one oxyethylene or oxypropylene unit; (b) an outer phase having a glass transition temperature of from 30° C. to 110° C. containing at least one ethylenic unsaturated monomer; (c) at least one pigment; (d) water; and (e) less than 3.0% by weight based on the total weight of the aqueous coating composition of anti-freeze agents.
