Abstract

"MATERIAIS PARA MEIOS DE REGISTRO óTICO DE ALTA DENSIDADE E RESPECTIVOS PROCESSOS DE OBTENçõES". Onde, especificamente, os materiais são compostos de quelato metálico de azocorantes, que são formados de compostos de m-diaminobenzeno sulfamoilados e azocompostos contendo um anel benzeno. Além disso, a invenção oferece um meio de registro ótico, caracterizado pelo fato de os referidos compostos de quelato metálico de azocorantes serem aplicados sobre o meio de registro ótico para formar uma camada de registro. A invenção também descreve um processo para a produção de um meio de registro ótico.
