    摘要: A resinous composition which comprises a compound having, in one molecule, one or more structures of the formula (1) ##STR1## wherein R.sup.1 is a hydrocarbon having 1 to 10 carbon atoms; R.sup.2, R.sup.3 and R.sup.4 are each hydrogen or a hydrocarbon group having 1 to 10 carbon atoms; and X is S or O, and a ratio of S to the total of S and O constituting the three-membered ring is 50% or more on the average; and another compound having one or more SH groups in one molecule. The resinous composition can be used for an optical material having improved oxidation resistance.
