PURPOSE: A resin composition for optical lens is provided to provide an optical lens with superhigh refractive index having excellent heat resistance without whitening, unbalanced polymerization, and edge bubbles. CONSTITUTION: A resin composition for optical lens comprises an optical resin prepolymer obtained by addition reacting one or more kinds of diisocyanate compound selected from hexamethylene diisocyanate, tolylene diisocyanate, and a xylene diisocyanate compound to a mercapto compound; and a diisocyanate compound. The optical resin prepolymer comprises an unreacted mercapto compound not reacted with the diisocyanate. 1-30 weight% of the diisocyanate compound is added to the mercapto compound. |
