Abstract

Procédé de teinture ou d'impression d'une résine hydrogel selon lequel on effectue l'impregnation de la résine hydrogel avec un colorant soluble dans l'eau ayant une grande affinité pour la résine hydrogel ou un leuco dérivé ou un composé incolore dérivé du colorant précité et qu'on traite ensuite le colorant précité ou le leuco dérivé ou le composé incolore dérivé du colorant précité, pour le rendre insoluble dans l'eau et capable de développer une coloration. On obtient ainsi une impression nette, résistant remarquablement à l'usure et au contact de l'eau, même à l'ébullition. Ce procédé est particulièrement utilisé pour le marquage des lentilles de contact souples.A method of dyeing or printing a hydrogel resin in which the hydrogel resin is impregnated with a water soluble dye having a high affinity for the hydrogel resin or a leuco derivative or a colorless compound derived from the dye above and then treating the above dye or the derivative leuco or the colorless compound derived from the above dye, to render it insoluble in water and capable of developing a color. A clear impression is thus obtained, remarkably resistant to wear and to contact with water, even at boiling point. This process is particularly used for the marking of soft contact lenses.
