Method for preparing composition containing colored silicate inorganic particles and composition containing colored silicate inorganic particles

摘要

A method for preparing a composition including silicate mineral particles that have coloring properties in which a talcose composition, including phyllosilicate mineral particles chosen from the group formed: from the particles having the chemical formula: ((SixGe1-x)4 M3O10 (OH)2, the particles having at least one interlayer space and having the chemical formula: (SixGe1-x)4 M3-ε O10 (OH)2, (M′m+)ε′.nH2O: -M having the formula Mgy(1)Coy(2)Zny(3)Cuy(4)Mny(5) Fey(6)Niy(7)Cry(8); -M′m+ designating at least one interlayer cation, the silicate mineral particles having a thickness of less than 100 nm and of which the largest dimension is less than 10 μπι, is brought into contact with a dye solution, including dye cations, of at least one element chosen from the transition metals, the lanthanides and the actinides. The composition obtained by this method is also described.
