Publication number: 20090047424Abstract: The present invention relates to tinted optical lenses and to methods of manufacturing tinted optical lens. This invention relates to a method for tinting optical lenses using an ink receptor film. The method of the invention allows a good transfer of the color to the substrate which represents the support of lens, a good final coloration of the substrate with good color homogeneity. The invention relate also to a method of tinting optical lenses, using the said ink receptor film which is applied onto a primer layer coating the substrate of the lens. The ink receptor material comprises an inorganic filler and an water-based emulsion. Preferably the ink receptor material also comprises a water-soluble polymer, a modified cationic polymer and a carrier able to accelerate the absorption of the ink into the substrate.Type: ApplicationFiled: January 25, 2006Publication date: February 19, 2009Applicant: Essilor International/ Nikon-Essilor Co., Ltd.Inventor: Tsukasa Momma
