ERASABLE RECORDING MEDIUM COMPRISING A DIMER ACID POLYAMIDE RESIN

摘要

Provided is an erasable recording medium and a method for recording and erasing same. The erasable recording medium comprises a thermally stable substrate and a polymeric layer deposited on the substrate comprised of a lower molecular weight dimer acid polyamide. Such a recording medium has excellent dimensional and mechanical stability on storage, readily and easily records information and has an ability to be easily and completely erased when erasure is desired.
