    Abstract: The present invention relates to a rare-earth borate, to a precursor thereof, to processes for their preparation and to the use of this borate as a luminophore. The rare-earth borate and the precursor thereof are characterized in that they are in the form of cubic, parallelepipedal or spherical particles and in that they have a dispersion index of not more than 0.8. According to one embodiment of the invention, the borate is a red luminophore. The process for the preparation of the precursor is characterized in that a rare-earth carbonate or hydroxycarbonate is reacted with boric acid, the reaction medium being in the form of an aqueous solution. The borate is obtained by calcination of the precursor.

    Abstract: The present invention concerns a sulfide of a rare earth and an alkali, a process for its preparation and its use as a colored pigment. The sulfide is characterized in that it has the formula ABS2 where A represents at least one alkali and B represents at least one rare earth and in that it is constituted by grains with an average size of 1.5 &mgr;m at most. The preparation process for the sulfide is characterized in that at least one rare earth carbonate or hydroxycarbonate is brought into the presence of at least one gas selected from hydrogen sulfide or carbon disulfide. The product obtained is optionally deagglomerated. The sulfide can be used as a pigment in plastics, paints, finishes, rubbers, ceramics, glazes, paper, inks, cosmetics, dyes, laminated coatings and materials based on or obtained from at least one inorganic binder.

    Abstract: The present invention relates to a composition based on a sulphur compound, zinc and optionally a transparent oxide, to a process for its preparation and to its use as a dye pigment. The composition of the invention is characterized in that it comprises a support based on at least one sulphur compound, and a zinc compound, deposited on the support and obtained by reaction of a zinc precursor with aqueous ammonia and/or an ammonium salt. The composition may also comprise a layer based on at least one transparent oxide deposited at the surface of the support and/or fluorine atoms. It may be prepared in particular by a process in which the support, a zinc precursor, aqueous ammonia and/or an ammonium salt and, if necessary, a transparent oxide precursor and a fluorinating agent are placed in contact and the zinc compound is deposited on the support and, where appropriate, the transparent oxide is precipitated on the said support.
