Abstract:
1. A polymerizable organic composition comprising one or more radically polymerizable monomers, at least one of which is a first monomer having at least two (meth)acryloyl groups and comprising one or more backbone linkages selected from the group consisting of thiourethane linkages and dithiourethane linkages, wherein a precursor of said first monomer is prepared from the reaction of a reactive hydrogen material comprising a polythiol having at least two thiol groups, and a monomer having at least two functional groups selected from at least one of the group consisting of isocyanate and isothiocyanate, and wherein the reactive hydrogen material further comprises a polyamine selected from the group consisting of ethyleneamines, C a diamine represented by the general formula (B): and a diamine represented by the general formula (C):
