SQUARYLIUM COMPOUND AND OPTICAL RECORDING MEDIUM CONTAINING THE SAME |
| 摘要 |
<p>An object of the present invention is to provide novel squarylium compounds having spectroscopic properties, light resistance, solubility and thermal decomposition properties suitable for a recording material for DVD-R, and optical recording media using the same. More particularly, the present invention provides novel asymmetric squarylium compounds represented by the general formula (I), having pyrazole and indoline skeletons in the molecule. In addition, the present invention provides optical recording media having a recording layer comprising said asymmetric squarylium compound. <CHEM></p> |
