Abstract
A coated particulate inorganic material includes a particulate inorganic material selected from at least one of titanium dioxide and a doped titanium dioxide, and a coating. The particulate inorganic material has an average crystal size of 0.4-2 μm. The coating includes a first and second layer. The first layer includes an inorganic oxide and/or an inorganic phosphate. The second layer is alumina. The first layer is from 0.1 to 2.2% w/w based on a total weight of the first layer with respect to a total weight of the particulate inorganic material. The second layer is 0.1 to 3.5% w/w based on a total weight of the second layer with respect to the total weight of the particulate inorganic material. The coating is from 0.2 to 4.5% w/w based on the total weight of the first and second layer with respect to the total weight of the particulate inorganic material.
