    摘要： A polymerizable composition according to the present invention is characterized by that it comprises a compound (a) having at least one structure represented by the following formula (1):
    wherein R 1 is a divalent hydrocarbon group having 1 to 10 carbon atoms, R 2 , R 3 and R 4 each independently represents a hydrocarbon group having 1 to 10 carbon atoms or a hydrogen atom; X stands for an S or O atom and the average number of S atom is at least 50% based on the total number of S and O atoms which consist of the three membered ring; and X' is -S- or -O-,
    at least two compounds (b) having a tertiary amino group substituted with aliphatic and/or aromatic group(s), which are each different in catalytic activity as a polymerization catalyst,
    with the proviso that the ratio of the total of the tertiary amino groups in the at least two compounds (b) to the episulfide groups in compound (a) is in the range of 0.0001 to 0.02 in terms of a molar ratio of amino/episulfide functional group.

    摘要： An optical resin prepared by curing a polymerizable composition comprising a (thio)epoxy compound having at least one intramolecular disulfide bond exhibits a considerably high refractive index while maintaining good optical properties and a high Abbe number. In addition, the above polymerizable composition to which is added primary and/or secondary amines as an yellowing inhibitor in a proportion of 0.001 to 0.5 of the total molar number of NH 2 and NH groups in the amines to the total molar number of thioepoxy and epoxy groups in the (thio)epoxy compound having at least one intramolecular disulfide bond, can provide a transparent resin in which yellowing and reduction in heat resistance associated therewith are adequately prevented while maintaining a high refractive index.
