Lightfast T102 pigment

Rutile TiO.sub.2 pigment particles bearing coatings consisting essentially of, in sequence:

• (a) an inner layer comprising about 0.05-1 percent by weight, based on the weight of the TiO.sub.2, of cerium radicals and about a stoichiometric amount of phosphate radicals needed to form cerium phosphate,
• (b) a second layer of about 0.1-4 percent by weight, based on the weight of the TiO.sub.2, of uncalcined amorphous silica, and optionally
• (c) an outer layer of (1) about 0.5 to 8 percent by weight, based on the weight of the TiO.sub.2, of hydrous alumina or (2) hydrous alumina in the amount of about 0.5-8 percent, based on the weight of the TiO.sub.2, and associated therewith up to about a stoichiometric amount of phosphate radicals needed to form aluminum phosphate, the combined total weight of said coatings being about 2 to 12 percent by weight, based on the weight of the TiO.sub.2, said particles not flocculating in aqueous media having a pH of about 6 to 8.
