DATA RECORDING MEDIUM |
摘要 |
<p>A data recording medium includes a recording layer which comprises a polymer liquid crystal and a metal chelate compound or soluble large cyclic colorant contained therein. The data recording medium shows a memory characteristic through utilization of phase transition between solid and a liquid crystal phase. The metal chelate compound or the soluble large cyclic colorant enhances the light-absorption characteristic, especially in the near infrared region without imparing the performances of the polymer liquid crystal.</p> |
