    • The invention provides a method for producing colored contact lenses with relatively high quality color images. The method of the invention comprises the steps of: obtaining a water based ink having a viscosity of greater than about 100 centipoise (cps) and the ink has a dynamic surface tension of less than about 40 dyne/cm at surface age of about 1 second; applying the ink to a portion of molding surfaces of a lens mold to form a colored coat; actinically curing the ink printed on the mold to form a colored film; dispensing a lens-forming material into the lens-forming cavity of the mold; and actinically or thermally curing the lens-forming material to form the contact lens, whereby the colored film detaches from the molding surface and becomes integral with the body of the contact lens.
    • 本发明提供一种生产具有较高质量彩色图像的有色隐形眼镜的方法。 本发明的方法包括以下步骤:获得具有大于约100厘泊(cps)的粘度的水基油墨,并且油墨在大约1秒的表面老化时具有小于约40达因/厘米的动态表面张力 ; 将油墨施加到透镜模具的成型表面的一部分以形成着色涂层; 对印刷在模具上的油墨进行光固化,形成着色膜; 将透镜形成材料分配到模具的透镜形成腔中; 并且使透镜形成材料进行光化或热固化以形成隐形眼镜,由此着色膜与成型表面分离并与隐形眼镜的主体成一体。
