ABSTRACT Commercial titanium dioxide pigments to be used in paper laminates have been prepared by a methods which involves calcining a coated pigment. A new pigment having an excellent stability to degradation by light when used in such laminates is produced without calcination of the coated pigment. The pigment comprises rutile titanium dioxide particles having an inner coating containing cerium and phosphate radicals and an outer coating containing aluminium and phosphate radicals and optionally hydrous alumina. The pigment preferably contains a surface stabiliser such as a fluoride, preferably calcium fluoride. Amounts of cerium phosphate are from 0.05% to 1% (as CeO2) and of aluminium phosphate between 0.005% and 5% by weight (as Al2O3) on TiO2.
