Abstract

La presente se refiere a un proceso para la fabricacion de artículos moldeados oftálmicos tenidos, el cual comprende los pasos de: (a) proporcionar unprecursor de polímero soluble en agua que tenga grupos reticulables o polimerizables; (b) proporcionar una dispersion de pigmento que comprenda un pigmentoinorgánico u orgánico, y un agente de dispersion; (c) mezclar la dispersion del pigmento con el precursor de polímero para formar una mezcla deprepolimerizacion tenida; (d) dosificar la mezcla deprepolimerizacion tenida en un molde; (e) aplicar radiacion a la mezcla de prepolimerizacion tenida en elmolde, reticulando o polimerizando de esta manera el precursor de polímero, y atrapando el pigmento adentro de la red polimérica del artículo moldeadooftálmico resultante; y (f) abrir el molde, de tal manera que se pueda remover el artículo moldeado oftálmico del molde. De acuerdo con el proceso, se preparanartículos moldeados oftálmicos tenidos, particularmente lentes de contacto blandos tenidos en todo el cuerpo, que tienen mejores propiedades, con unaeficiencia mejorada.
