Abstract

An embodiment relates to a polymerizable composition for a plastic lens. The polymerizable composition for a plastic lens according to the embodiment comprises a nonhalogenated tin-based catalyst and a diketone compound as a low-temperature reaction rate controlling agent. Accordingly, the polymerizable composition has a more stable pot life so that the polymerization rate can be appropriately controlled, thereby improving the reactivity and the workability, and that the generation of bubbles are prevented, thereby improving the transparency of the resin.
