Abstract

"MOLDAGEM OFTáLMICA DE ALTA Dk, COLORIDA E MéTODO PARA FABRICAçãO DA MESMA". A presente invenção refere-se a formulações de moldagem oftálmica e a moldagens oftálmicas de alta Dk, coloridas. Esta invenção também refere-se a um método para fabricação de uma moldagem oftálmica colorida. O método compreende: (a)provimento de um precursor de polímero tendo grupos reticuláveis ou polimerizáveis; (b) provimento de uma dispersão de pigmento compreendendo um pigmento inorgânico ou orgânico e um agente dispersante; (c) mistura de dispersão de pigmento com o precursor de polímero para formar uma mistura de pré-polímero colorida; (d) dispensamento de mistura de pré-polímero colorida em um molde; e (e) formação de uma moldagem oftálmica colorida a partir da mistura de pré-polímero colorida, a moldagem compreendendo uma matriz de polímero tendo o pigmento ali arrastado. Com este método, moldagens oftálmicas coloridas, particularmente lentes de contato coloridas, macias borda-a-borda tendo propriedades aperfeiçoadas, são preparadas com uma eficiência aperfeiçoada.
