Method for incorporating an additive into a thin film formed on a substrate and uses thereof in ophthalmic optics

摘要

The present invention relates to methods of incorporating additives into a thin film formed on a substrate comprising:forming an impregnatable thin film on at least one face of a substrate;depositing an impregnation composition comprising at least one additive incorporated in an appropriate diluent medium on said impregnatable thin film by spin coating;diffusing the impregnation composition within said impregnatable thin film and;treating the substrate coated with the impregnated thin film to at least partially remove the diluent medium from the impregnated thin film.The invention also relates to the application of such methods to the production of optical lenses, including in the coloring of such lenses.
