摘要：
The present invention provides an optical recording medium including a substrate and a recording layer on the substrate having a squarylium metal chelate compound with a central metal. The recording layer includes a mixture of squarylium metal chelate compounds having ligands of the same type as well as metals of two or more types as the central metal. It is preferable that the recording layer includes a squarylium metal chelate compound having a bivalent metal as its central metal and a squarylium metal chelate compound having a metal other than a bivalent metal as its central metal.
