Abstract
Provided is a process which can be carried out upon the production of a polyurethane/thiourethane-based resin with the use of a polyisocyanate compound, a polyol compound, and a polythiol compound, without causing abrupt heat generation or viscosity increase. At least one polyol compound having at least one ether bond and two or more hydroxy groups in a molecule is used as the polyol compound, whereby a large heat generation or an abrupt viscosity increase are prevented from occurring upon blending monomer.
