Abstract
The present invention relates to a process for pigmenting a porous sintered material comprising boride, carbide, silicide, nitride or phosphide compounds by applying a solution of a soluble pigment derivative to the non-coloured sintered material and regenerating the organic pigment by heating, whereby the organic pigment is deposited into the sintered material's pores, as well as to the new pigmented sintered materials themselves.
