Patent ID: 6933415

Claim:
A aqueous coating composition, comprising: (a) 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 —, and R 2 is —O—CH 2 —CH(CH 2 —O—C 6 H 4 —R 3 )—O—(CH 2 —CH 2 —O) n —R 4 , —O—(CH 2 —CH 2 —O) n —R 4 , —O—(CH 2 —CH(CH 3 )—O) n —R 4 , —O—(CH 2 —CH 2 —O) m —(CH 2 —CH(CH 3 )—O) n —R 4 or —O—(CH 2 —CH(CH 3 )—O) m —(CH 2 —CH 2 —O) n —R 4 ; R 3 is an alkyl group; R 4 is hydrogen, sulfonate (—SO 3 M), sulfate (—SO 4 M), phosphonate (—PO 3 M) or phosphate (—PO 4 M); M is H + , Na + , NH 4 + , K + or Li + ; n is from about 5 to about 100; and m is from 0 to about 100; (b) at least one pigment; (c) water; and (d) less than 3.0% by weight based on the total weight of the aqueous coating composition of anti-freeze agents.
