摘要：
Disclosed is an internal mold release agent for the production of polythiourethane optical materials, which is obtained by mixing an acidic phosphate ester compound and at least one metal selected from the group consisting of Zn, Cu, Fe, Ga, Bi, Al and Zr. The internal mold release agent for the production of polythiourethane optical materials contains the metal in an amount of 0.01 to 20 weight %.
