Abstract
La présente invention concerne un support d'enregistrement d'information optique qui comprend : un substrat comprenant une rainure préalable avec un pas transversal de 50 à 500 nm formé à sa surface ; et une couche d'enregistrement formée sur la surface du substrat et comprenant un colorant complexe métallique azoïque représenté par la formule générale (A). [Formule générale (A)] A (Xp+)k' dans laquelle A représente une fraction anionique représentée par la formule : (L2-)2(M) ; L2- représente un anion de colorant azoïque bivalent ; M représente un ion métallique ou un ion d'oxyde métallique ; Xp+ représente un cation organique à valence p qui présente un coefficient d'extinction molaire maximum de moins de 20 000 dm3mol-1cm-1 dans une plage de longueurs d'onde allant de 350 à 700 nm lorsque le cation organique et un ion Cl- ou analogue forment ensemble un sel ; p représente un entier de 1 à 10 ; et k' représente une valeur déterminée en divisant une charge négative de la fraction anionique représentée par A par la valeur p et est contenu dans la plage suivante : 0 < k' ≤ 4, sous réserve que Xp+ n'est pas un cation d'ammonium alkylique non cyclique.
