PURPOSE:To provide an optical recording medium having good weatherability and signal quality by forming a layer consisting of 3,4,9,10-perylene tetracarboxylic dianhydride between a substrate and recording layer. CONSTITUTION:The layer 3 consisting of the 3,4,9,10-perylene tetracarboxylic dianhydride (PTCDA) is inserted between the substrate 1 and the recording layer 2. Warpage is thereby prevented. |
