Beschreibung
Zusammenfassung:	A polymerizable composition for an optical material containing two or more different monomers for an optical material, and a polymerization catalyst, in which at least one of the two or more different monomers for an optical material is an isocyanate compound containing no aromatic rings, a content of the polymerization catalyst with respect to a total of 100 parts by mass of the two or more different monomers for an optical material is from more than 0.05 parts by mass to 2.0 parts by mass, and a viscosity measured by a B-type viscometer at 25° C. and 60 rpm is from 10 mPa·s to 1,000 mPa·s.
