    Abstract: Complex inorganic titanate pigments with low dopant levels (i.e., less than about 5%) exhibit coloristic and enhanced infrared (IR) reflectance characteristics that make them useful in formulating colors exhibiting high IR reflectivity. This characteristic is becoming increasingly useful as a way to keep exterior surfaces and articles cooler during exposure to direct sunlight. Achieving this can decrease energy (e.g., cooling/air conditioning) consumption and costs. Low-loaded titanates can boost IR reflectivity by 1 to 10% in selected visual color spaces. Paint compositions containing those low loaded titanate pigments and a method for providing a surface with high infrared reflectance utilizing those pigments are also disclosed.

  • Publication number: 20100282128
    Abstract: A method of predicting photostability of coatings with various dopants on titanium dioxide pigment particles is disclosed. Calculations of the density of states show that a doped coating which reduces the density of states near the band edge or increases the density of states within the band gap of the pigment particles increases the photostability of the doped pigment.

    Abstract: The present invention relates to novel pigment mixtures comprising at least two different particulate components A and B. The first component A comprises titanium suboxide(s), a titanium oxynitride or a titanium nitride species. Component B particle comprises inorganic, or organic pigments. The titanium suboxide particles display a bluish metallic luster, are new and form a further aspect of the present invention. When combined with particles from component B such as variously coated micas, for example, the bluish or bluish/black metallic color effect from component A leads to special color effects in the various mixtures.
