Abstract
The present invention relates to a process for pigmenting a porous metal oxide by applying a solution of a soluble pigment derivative and regenerating the organic pigment by heating, whereby the organic pigment is deposited into the metal oxide's pores. The invention also relates to pigmented porous metal oxides and materials comprising a solid substrate and a surface layer of a pigmented metal oxide.
