Abstract
Indolestyryl-Verbindungen und deren Verwendung für ein Hochdichte-Aufnahmemedium und Verfahren zu ihrer Herstellung. Die Indolestyryl-Verbindungen weisen ein starkes Absorptionsvermögen im Bereich sichtbaren Lichts (400 APPROX 700 nm) des Spektrums, Widerstandsfähigkeit gegenüber Hitze und Licht, hohe Lichtempfindlichkeit und exzellente, aus ihrer speziellen chemischen Konfiguration resultierende Löslichkeit auf. Weiterhin können die Indolestyryl-Verbindungen als Aufnahmesichtmaterialien in Hochdichte-Aufnahmemedien zum Anpassen einer Laser-Lesewellenlänge und zur Steigerung des Reflexionsindex und des Träger-Rausch-Verhältnisses (CNR) des Hochdichte-Aufnahmemediums verwendet werden. Dementsprechend kann die Aufnahmeempfindlichkeit und die Auslesecharakteristik des die Indolestyryl-Verbindung gemäß der vorliegenden Erfindung umfassenden Aufnahmemediums verbessert werden.
