Abstract
The disclosure is related to a polymerizable composition for coloring contact lens, comprising a composite colorant and at least one hydrophilic monomer. The composite colorant is produced by a reaction of a colorant precursor and a (methyl)methacryloxy group-containing silane coupling agent. The colorant precursor is produced by a reaction of a metal oxide and a siloxane compound under alkaline solution.
