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.

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: A retail point of sale expanded color space white-pigmented paint and non-pigmented stain custom tinting dispenser system with an automated colorant or pigment dye dispenser having a minimum liquid dispensing quantity less than 0.01 fluid ounce or 0.3 cm3 typically less than 0.005 fluid ounce or 0.15 cm3. No more than twelve colorants are used, typically ten or less. The colorants used include white; black; yellow hued; green-hued colorant having a colour strength greater than 12 wt. % PG7 pigment and typically 20-48% PG7 pigment; blue-hued colorant containing at least 7 wt. % PB 15:2 pigment and typically 12-28% PB15:2 pigment; and red-hued colorant at least containing 17 wt. % PR209 pigment and typically 29-68% PR209 pigment.

Abstract: Custom-tinted paints and stains are made using an array of low VOC concentrated liquid colorants including at least at least white colorant; black colorant; and green-hued, blue- hued and red-hued primary colorants at least one of which primary colorants comprises polyalkylene glycol humectant, ethoxylated surfactant and extender pigment. For colorants in the array containing polyalkylene glycol humectant, the humectant and ethoxylated surfactant amounts are sufficiently high and extender pigment amount is sufficiently low so that the colorants will not problematically plug colorant dispenser orifices if left in the dispenser without an orifice cap for a full day. The polyalkylene glycol humectant is also present in an amount sufficiently low so that dried paint films made by mixing the colorants with a clear waterborne base paint will resist blocking.

Abstract: A universal colorant system for both solvent- and water-based paints and coatings is contained in a closed sealed pouch or cartridge-style container, and includes a colorant component, a surfactant package including at least one alkyd-compatible surfactant and at least one latex-compatible surfactant, and a carrier. When the colorant system is added to a base paint it desirably provides a mixture having a drop in viscosity of less than about 50%.
