摘要:
A composite particulate pigmentary material is disclosed which comprises an association of at least two chemically distinct materials in which the particles of one material carry a positive surface charge and the particles of the second material carry a negative surface charge and particles are held in association as a result of these surface charges. Also disclosed is a method for preparing composite particulate pigmentary material comprising forming aqueous dispersions of two particulate materials under conditions in which the surface charges of the particles of the two materials are of different signs and mixing the dispersions. Typical materials useful for preparing the composite include inorganic pigments, fillers and extenders and organic polymeric microspheres. The product is useful as a pigment in, for example, paints, inks, paper and plastics.

摘要:
The invention provides a composition imparting UV protective capability comprising an effect coated particulate material having a substantially rutile crystal habit and an average particle size greater than or equal to about 0.5 μm dispersed in a medium at a concentration within a range of about 1% by volume to about 40% by volume, based on the total volume of composition. The composition may be coloured or non-coloured and applied onto one or more surfaces of a substrate to provide UV light protection without also increasing UV light activated photocatalytic effects which are generally observed.
摘要:
A colored 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.
