Abstract

La invención se refiere a un proceso nuevo para la producción de productos moldeados coloreados, en particular lentes de contacto coloreados, en donde un polímero coloreado reticulable que comprende unidades que contienen un grupo reticulable y unidades que contienen un radical de tinte reactivo se degrada en solución, y a moldeos coloreados, en particular lentes de contacto coloreados, que se obtienen por este proceso. La presente invención se refiere también a ploímeros coloreados reticulables nuevos que comprenden unidades que contienen un grupo reticulable y unidades que contienen un radical de tinte reactivo que se puede emplear en el nuevo proceso, en particular, derivados de un alcohol de polivinilo con un peso molecular de por lo menos aproximadamente 2000, a polímeros coloreados reticulados, ya fuere homopolímeros o copolímeros, fabricados de estos polímeros coloreados reticulables nuevos que contienen un radical de tinte reactivo, un proceso para la prepración de los nuevos polímeros coloreados reticulables que comprenden unidades que contienen un grupo reticulable y unidades que contienen un radical que tinte reactivo y los homopolímeros y copolímeros que se obtiene de esto, a moldeos coloreados fabricados de dichos homopolímeros o copolimeros en particular, lentes de contacto coloreados fabricados de estos homopolímeros o copolimeros y a un proceso para la producción de lentes de contacto coloreadas utilizando dichos homopolímeros o copolímeros.The invention relates to a novel process for the production of colored molded products, in particular colored contact lenses, wherein a crosslinkable colored polymer comprising units containing a crosslinkable group and units containing a reactive dye radical is degraded in solution , already colored casts, in particular colored contact lenses, which are obtained by this process. The present invention also relates to novel crosslinkable colored ploimers comprising units containing a crosslinkable group and units containing a reactive dye radical which can be employed in the new process, in particular derivatives of a polyvinyl alcohol with a molecular weight of at least about 2000, to crosslinked colored polymers, either homopolymers or copolymers, made from these new crosslinkable colored polymers containing a reactive dye radical, a process for the preparation of new crosslinkable colored polymers comprising units containing a crosslinkable group and units containing a reactive dye radical and the homopolymers and copolymers obtained therefrom, to colored molds made of said homopolymers or copolymers in particular, colored contact lenses made of these homopolymers or copolymers and to a process for the production lens Colored contact s using said homopolymers or copolymers.
