INK COMPOSITION FOR COSMETIC COLOR CONTACT LENS

摘要

The present invention relates to an ink composition for cosmetic color contact lens and, more specifically, to an ink composition for cosmetic color contact lens, which is bio-friendly due to using self-photoinitiating silicone acrylate and hyperbranched acrylate instead of a photoinitiator harmful to a human body. The ink composition for cosmetic color contact lens reduces a producing time of the color contact lens by introducing a photocurable system to an existing heat curable system, increases productivity, and shows high calorific value and a curable conversion rate due to using hyperbranched acrylate which increases curable properties.
