(57) [Summary]nThe present invention relates to the use of β-type rare earth metal sulfide as a color pigment and a method for producing the same. Β-type rare earth metal sulfides whose rare earth metal is lanthanum, cerium, praseodymium, samarium or neodymium are used. The sulphides consist of perfect crystallites, which form aggregates of medium dimensions of at most 1.5 μm. The method for producing a rare earth metal sulfide is characterized by reacting a rare earth metal compound with at least one kind of sulfurizing gas selected from hydrogen sulfide or carbon sulfide. Pigments are based on at least one inorganic binder of the following types of compositions: plastics, paints, varnishes, rubbers, ceramics, glazes, papers, inks, cosmetics, dyes, leather, laminated coatings or other types Alternatively, it is a part of a composition obtained from the composition. |
