Abstract
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: ((SiGe)MO(OH), the particles having at least one interlayer space and having the chemical formula: (SiGe)MO(OH), (M').nHO: -M having the formula MgCoZnCuMnFeNiCry(8); -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.
