The invention provides a colorant for use in tinting contact lenses in which the binding polymer used is capable of forming an interpenetrating polymer network with the lens material. When the colorants of the invention are applied to uncured lens material that is subsequently cured, the binding polymer forms an interpenetrating polymer network with the lens material embedding the colorant within the lens material resulting in a stable, tinted lens.
Cette invention porte sur un colorant utilisé pour teinter des lentilles de contact dans lequel le polymère liant utilisé peut former un alliage IPN avec le matériau de la lentille. Quand on applique les colorants de l'invention sur des matériaux de lentille non apprêtés, le polymère liant forme un alliage IPN avec le matériau de la lentille incorporant le colorant à l'intérieur du matériau de la lentille. Il en résulte une lentille teintée stable.
