Disclosed are compositions comprising an aqueous dispersion of a finely divided organic substance and a sequestering agent. The sequestering agent is a linear, water-dissipatable polymer having an inherent viscosity of at least about 0.1 and comprising the reaction products of the following components or ester forming or esteramide forming derivatives thereof; n (a) at least one dicarboxylic acid; n (b) at least one difunctional sulfomonomer containing at least one metal sulfonate group attached to an aromatic nucleus wherein the functional groups are hydroxy, carboxyl or amino; and n (c) a glycol or a mixture of a glycol and diamine having two --NRH groups, the glycol containing two --CH 2 --OH groups of which from at least 0.1 mole percent based on the total mole percent of hydroxy or hydroxy and amino equivalents, is a poly(ethylene glycol) having the structural formula: n n H--(--OCH.sub.2 --CH.sub.2 --)--.sub.n OH n n n being an integer of between 2 and about 500, with the proviso that the mole percent of said poly(ethylene glycol) within said range is inversely proportional to the quantity of n within said range. The reaction components may also include one or more difunctional reactants selected from a hydroxycarboxylic acid having one --CR 2 --OH, an aminocarboxylic acid having one --NRH group, an amino-alcohol having one --CR 2 OH group and one --NRH or mixtures thereof, wherein each R is an H atom or an alkyl group of 1 to 4 carbon atoms. |
