Latexes are thicknened by a blend of a urethane compound effective as an associative thickener and a non-urethane compound of the formula: R -(O-A)a-B -R -(B -R )d-(B -(A'-O)b-f-(A'-B )f-R -(B -R )e)n-B -(A"O)c-R , wherein R and R are monovalent hydrophobic groups independently selected from the group consisting of an aliphatic group, a substituted aliphatic group, an aromatic group, and a substituted aromatic group; R and R are independently selected from the group consisting of aliphatic, substituted aliphatic, aromatic, or substituted aromatic radicals, each radical being divalent or trivalent; R and R are independently selected from hydrogen, lower alkyl and lower aralkyl; B , B , B , B , B and B are linking groups independently selected from the group consisting of an oxygen atom (to form the ether linkage -O-), a carboxylated group (to form an ester linkage R -C(O)-O- and/or R -C(O)-O-, an amino group to form the amine linkage R -N(R)- and/or R -N(R)-, wherein R is hydrogen, lower alkyl, lower aralky, or lower acyl), and an amido group (to form the amide linkage R -N(R)-C(O)- and or R -N(R)-C(O)-, wherein R is hydrogen, lower alkyl, lower aralkyl, or lower acyl); each of a, b, c, d, e, f and n are integers, wherein each of a and c are independently any integer from greater than 20 to about 200; b is any integer from greater than 20 to about 450; d, e, and f are zero or 1; and n is any integer from 1 to about 5; and each of A, A' and A'' is independently an ethylene, 1,2-propylene, 1,2-butylene unit or combinations thereof.
