1. A method for preparing an organic/inorganic hybrid composition comprising non-swelling phyllosilicate nanoparticles having a thickness of 1 nm to 100 nm, and a largest dimension of 10 nm to 10 μm, and at least one molecule chosen from colored charged organic molecules, said organic molecule being adsorbed on the phyllosilicate nanoparticles, this method comprising at least bringing into contact, in a monophasic solvent medium, said at least one colored charged organic molecule with said non-swelling phyllosilicate nanoparticles.
