Abstract: The present invention relates to a stable aqueous pigment dispersion including: an aqueous medium, pigment particles, and from 0.1% to 15%, by weight based on the weight of pigment, of a certain first water-soluble polymer; and 2) a certain second water-soluble polymer; wherein the dispersant comprises a proportion of the first polymer to the second polymer of from 0.1:1 to 10:1 on a solids basis, and the first polymer and the second polymer are miscible in those proportions; and wherein the dispersant is substantially free of structural units of phosphorus acid monomers and their salts. The invention also relates to a method for forming the stable aqueous dispersion and a dry coating formed from the aqueous dispersion. The stable aqueous dispersion is useful, inter alia, for forming certain composite particles.

Abstract: The present invention relates to a process for preparing a coatings composition with an open time additive comprising the steps of a) contacting an aqueous dispersion of alkali swellable polymer particles with a rheology modifier and a binder to form a coatings composition with a VOC of less than 50 g/L; and b) neutralizing the alkali swellable particles with a non-volatile base after or upon contact with the rheology modifier and the binder to form swelled multi-staged polymer particles; wherein the alkali swellable polymer particles comprise a shell having a Tg of not greater than 25° C. and an acid functionalized core; and wherein the core-to-shell ratio is in the range of from 1:3.2 to 1:10. The composition arising from the process of the present invention is useful for improving open time, especially for low VOC coatings applications.In another aspect the present invention relates to the preparation of the coatings composition with an open time additive comprising the steps of a) contacting the open time additive with a rheology modifier and a binder to form a coatings composition with a VOC of less than 50 g/L, then b) neutralizing the open time additive to form swelled multi-staged polymer particles, wherein the coatings composition with the open time additive exhibits less than a 50% increase in viscosity than the coating composition without the open time additive.

Abstract: The present invention is a composition comprising a) a stable aqueous dispersion of polymer particles functionalized with structural units of a phosphorus acid monomer or a salt thereof and; b) a water-soluble polymer functionalized with structural units of a sulfonic acid monomer or a salt thereof as well as a method comprising mixing the stable aqueous dispersion of the phosphorus acid functionalized polymer particles with the sulfonic acid functionalized polymer, and TiO2. The composition of the present invention is useful as a coatings formulation that provides improved hiding over phosphorus acid functionalized binders that do not include the water-soluble polymer. Alternatively, the same hiding benefit is seen at lower phosphorus acid concentration when the sulfonic acid functionalized polymer is present.
