摘要：
The present invention discloses a sulfur-containing urethane-based resin composition
which comprises a polythiol compound represented by formula (1):
wherein X 1 , X 2 and X 3 each is a hydrogen atom or a mercapto group; x, y and z each is an integer of 0 to 8; and in their combinations, formula (1) has at least two mercapto groups,
a polyiso(thio)cyanate compound, and a compound having two or more reactive unsaturated groups in an amount of 30 to 70% by weight based on the total weight of the composition, or a sulfur-containing urethane-based resin composition which comprises the polythiol compound represented by formula (1), the polyiso(thio)cyanate compound, the compound having two or more reactive unsaturated groups in an amount of 10 to 70% by weight based on the total weight, and a photopolymerization catalyst.
