Zusammenfassung:	PCT No. PCT/JP97/02079 Sec. 371 Date Dec. 8, 1998 Sec. 102(e) Date Dec. 8, 1998 PCT Filed Jun. 17, 1997 PCT Pub. No. WO97/48745 PCT Pub. Date Dec. 24, 1997Disclosed herein are a plastic lens material having both excellent optical and mechanical properties and having a low specific gravity, and a production process for producing the plastic lens material having excellent various properties and a low specific gravity. The plastic lens material comprises a copolymer obtained by radical-polymerizing a reaction product of a component [A] containing a polyhydric alcohol obtained by subjecting a dimer and/or a trimer of a higher unsaturated fatty acid having 11 to 22 carbon atoms with a component [B] containing an isocyanate compound having a radical-polymerizable unsaturated bond in its molecule together with a copolymerizable monomer [C].
