Abstract: The present invention relates to the use as an antisoiling coating of a porous coating comprising a polysiloxane matrix and a porous volume such that the potential filling ratio of the total volume of said coating by oleic acid is at least 25% by volume, having a porosity rate ranging from 25 to 70% by volume and having no photocatalytic properties. The antisoiling porous coating is self-cleaning, easy to clean and can be regenerated by simple washing. It is mainly intended for use in ophthalmic optics, and proves to be very effective against sebum. In the preferred embodiment of the invention, this coating has a mesoporous structure.

Abstract: The present invention relates to a method for making a substrate coated with a mesoporous photochromic film, comprising: a) preparing a precursor sol of a mesoporous film comprising an inorganic precursor agent, at least one organic solvent, water, at least one pore-forming agent and one hydrophobic precursor agent bearing at least one hydrophobic group; b) depositing a film of the precursor sol onto a main surface of a substrate; c) removing the pore-forming agent from the film resulting from the previous step at a temperature ≦150° C.; d) impregnating the mesoporous film resulting from step c) with a solution comprising at least one photochromic agent. In an alternative embodiment, the photochromic agent is directly introduced into the precursor sol. In an alternative embodiment of the previous alternative embodiment, the precursor sol does not comprise any hydrophobic precursor agent but the photochromic film is made hydrophobic by a treatment subsequent to its preparation.
