摘要： Provided are a polymerizable composition which can suppress generation of turbidity, optical distortion, and striae in a transparent resin obtained therefrom, a transparent resin obtained from the polymerizable composition, an optical material containing the transparent resin, a plastic lens containing the optical material, and a method for manufacturing the transparent resin.
A polymerizable composition of the present invention contains a polythiol compound having at least three mercapto groups and a polyiso (thio) cyanate compound having at least one aromatic ring. A thiol equivalent ratio which is a measured value of a thiol equivalent of the polythiol compound with respect to a theoretical value of the thiol equivalent is 0.975 or more and less than 1.000.
