Abstract
According to the present invention, a polymerizable composition having excellent storage stability can be provided by adding an acid that serves as a stabilizing agent and a free-radical polymerization inhibitor to a polymerizable composition that contains a polythiol compound and an enic compound having a phenylthio backbone as monomer components. In the present invention, an embodiment in which the acid is at least one compound having a protonic-acid-type functional group which is selected from phosphoric acid, phosphonic acid, phosphinic acid, sulfonic acid, sulfoneimide and carboxylic acid is preferred.
