摘要：
The present invention discloses a composition for high refractive index plastic lens consisting of a monomer mixture wherein a particular aliphatic thiol compound is added to a polyisocyanate represented by general formula (1) :
wherein each X represents a hydrogen atom or a methyl group ; each R represents a chlorine atom, a bromine atom, a methyl group or an ethyl group ; m represents an integer of 0-4 ; and n represents an integer of 2-4, and a polythiol of formula (2) :
and a high refractive index plastic lens made of a urethane-containing resin obtained by polymerizing said composition.
