摘要：Disclosed is a process for producing effectively a high performance opticalmaterial (e.g. a lens) made of a polyurethane resin, which is transparent and colorlesswithout a strain. In this process, the optical material is produced without causing striationor clouding by polymerizing a polymerizable composition comprising a polythiolcompound and a polyiso(thio)cyanate compound, and characterized in that a watercontent in the composition is 10 to 300 ppm.
