Abstract:
The present invention relates to a composition comprising: a) an aqueous dispersion of i) polymer particles functionalized with structural units of a phosphorus acid monomer; and ii) TiO2 particles; b) a sulfur acid functionalized dispersant; and c) a carboxylic acid functionalized dispersant. The composition of the present invention addresses a need in the art by providing a way to tune TiO2-binder composite formation efficiency with relative ease.
