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.
本发明涉及一种为包含硼化物、碳化物、硅化物、氮化物或磷化物化合物的多孔烧结材料着色的工艺,方法是在不着色的烧结材料上涂抹可溶性颜料衍生物溶液,并通过加热使有机颜料再生,从而使有机颜料沉积到烧结材料的孔隙中以及新的着色烧结材料本身。
