    摘要: A coloured composition comprising: a) NIR scattering TiO2 particulate material with an average crystal size of greater than 0.40 μm and a particle size distribution such that 30% or more of the particles are less than 1 μm; b) one or more non-white colorant; wherein the particulate material and the non-white colorant are dispersed within a vehicle. This material with a large crystal size has unusually high reflection of NIR radiation and, simultaneously, noticeably diminished reflectance of visible light. Also disclosed is a coated particulate TiO2 material, wherein the material has an average crystal size of greater than 0.40 μm, and the coating comprises one or more oxide material; this provides low levels of photocatalytic activity that were previously unattainable. This coated TiO2 material may be provided in a composition.
