    Abstract: Titanium dioxide may be more efficiently used in a coating composition containing a composite pigment particle-forming polymer if during composite formation, the polymer is initially present in a low concentration and the titanium dioxide particles and newly- formed composite particles are dispersed in a waterborne emulsion polymer that does not form such a composite. A pigment grind dispersion of titanium dioxide pigment-polymer composite particles may be made by mixing titanium dioxide particles with the waterborne emulsion polymer. The composite-forming polymer is then added to the waterborne emulsion polymer, or is added independently and concurrently with the titanium dioxide particles. The resulting titanium dioxide pigment-polymer composite particles provide improved coating composition opacity compared to a coating composition that does not contain such composite particles. The coating compositions can contain reduced titanium dioxide amounts and less than a saturation level of the composite-forming polymer.

    Abstract translation: 二氧化钛可以在含有复合颜料成粒聚合物的涂料组合物中更有效地使用，如果在复合形成期间，聚合物最初以低浓度存在，并且二氧化钛颗粒和新形成的复合颗粒分散在水性乳液中 不形成这种复合材料的聚合物。 二氧化钛颜料 - 聚合物复合颗粒的颜料研磨分散体可以通过将二氧化钛颗粒与水性乳液聚合物混合来制备。 然后将复合形成聚合物加入到水性乳液聚合物中，或者与二氧化钛颗粒独立并同时加入。 与不含这种复合颗粒的涂料组合物相比，所得到的二氧化钛颜料 - 聚合物复合颗粒提供改进的涂料组合物不透明度。 涂料组合物可以含有还原的二氧化钛量并且低于复合成型聚合物的饱和水平。

    Abstract: A pigment grind dispersion of titanium dioxide pigment-polymer composite particles is made by mixing titanium dioxide particles with an aqueous emulsion containing (i) less than a saturation level amount of water-insoluble film-forming first polymer particles that adsorb to the titanium dioxide particles, and (ii) an inhibiting or interfering amount of water-insoluble film-forming second polymer particles that do not adsorb to the titanium dioxide particles, wherein the pigment grind dispersion has a titanium dioxide pigment volume concentration of about 25 to about 50 and a titania composite ratio of about 32 to about 60. The resulting titanium dioxide pigment-polymer composite particles can provide improved coating composition opacity compared to a coating composition that does not contain such composite particles, can employ reduced titanium dioxide amounts and less than a saturation level of the first polymer, and can provide improved storage stability.
