摘要：
Method for dyeing a substrate prepared by curing a polymerizable composition having one monomer containing one episulfide group, the method including: providing a dye solution including a dye and a carrier in a solvent, the carrier being chosen from the compounds represented by the following formulae (1) and (2): wherein R1, R2, R3 and R4 are each selected from the group consisting of alkyl having from 1 to 10 carbon atom, H, —CH2SH, —CH2SCH2CH2SH, wherein m denotes an integer from 1 to 3; and at least partially immersing the substrate in the dye solution for a time sufficient to allow the effective tinting of the substrate.
