摘要：
An object of the present invention is to provide novel squarylium compounds having the 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 squarylium compounds represented by the general formula (I). In addition, the present invention provides optical recording media having a recording layer containing said squarylium compound.
