Abstract
A thermosetting resin, epoxy resin, substrate for computer-use-write-once, phase-change, and magnetooptical memory disks has been developed, and its optical, physical, thermal, and mechanical properties are described compared with other plastic substrates. The epoxy resin substrate has advantages of high heat deflection temperature and very low birefringence due to the casting mold. The resistance of the epoxy resin substrate against chemical reagents exhibits excellent chemical resistance except methylene chloride; it is also suitable as a substrate for organic dye write-once media.
