Abrégé
(EN)
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.

La présente invention concerne un moyen d’enregistrement optique comprenant un substrat et une couche d’enregistrement sur le substrat comportant un composé chélaté de métal de squarylium avec un métal central. La couche d’enregistrement comprend un mélange de composés chélatés de métal de squarylium comportant des liants du même type de même que des métaux de deux ou de plus de types que le métal central. Il est préférable que la couche d’enregistrement comprenne un composé chélaté de métal de squarylium comportant un métal bivalent comme métal central et un composé chélaté de métal de squarylium comportant un métal autre que bivalent comme métal central.
