Abstract:
Method for dyeing a substrate prepared by curing a polymerizable composition comprising one monomer containing one episulfide group, said method comprising: - providing a dye solution comprising a dye and a carrier in a solvent, the carrier being chosen from the compounds represented by the following formulae (1) and (2): formula (1) : 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, Formula (III), Formula (IV); * formula (2) : (HSCH2)4-mC(CH2SCH2CH2SH)m (2) 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.
