<p>A material for plastic lenses, comprising at least one group represented by the following formula (1) as a terminal group and a group represented by the following formula (2) as a repeating unit.wherein each R1 independently represents an allyl group or a methallyl group, A?1 and A2¿ each independently represents an organic residue derived from a dicarboxylic acid or a carboxylic anhydride, and each X independently represents an organic residue derived from a polyhydric alcohol having from 2 to 3 hydroxyl groups and containing an alicyclic structure within the molecule, provided that by the ester bonding, X can have a branched structure having a group of formula (1) as a terminal group and a group of formula (2) as a repeating unit.</p> |
