PURPOSE: A resin composition for optical lens is provide to have excellent thermal stability, to have good releasability because of controlled polymerization rate, and to prevent phenomenon being separated between a lens and a mold in advance, by minimizing unbalance of polymerization. CONSTITUTION: A resin composition for optical lens comprises 30.0-80.0 weight% of a resin in chemical formula 1, 0.01-5.0 weight% of one or more kinds of thermal stabilizers, 10.0-60.0 weight% of one or more kinds of reactive diluents, and 0.01-10.0 weight% of a molecular weight modifier. The liquid-phase viscosity at 25°C is 20-1,000 cpas, the liquid-phase refractive index is 1.50-1.58, and the solid-phase refractive index is 1.58-1.61. In chemical formula 1, n is 0-10, R1 is H or CH3, and R2 is H or Br. |
