Abstract
"MATERIAIS DE GRAVAçãO óPTICOS TENDO ALTA DENSIDADE DE ARMAZENAMENTO". A invenção refere-se a um meio de gravação óptico compreendendo um substrato, uma camada de gravação e uma camada refletora, no qual a camada de gravação compreende um composto de fórmula ou um tautómero ou um sal dele. Para as definições precisas dos substituintes, faz-se referência na descrição. A gravação e a reprodução são conduzidas especialmente a um comprimento de onda de 350 a 500 nm, usando, por exemplo, um laser azul. A qualidade da gravação e da reprodução é excelente e propicia uma alta densidade de armazenamento. Também são reivindicados meios de gravação ópticos para gravação ou reprodução a 380 - 440 nm, que compreendem um composto tendo uma absorção máxima na faixa de ondas de 300 a 400 nm e um composto de fórmula (IX).
