Abstract

USO DE CORANTES DE áCIDOS ESQUáRICOS EM CAMADAS óPTICAS PARA GRAVAçãO DE DADOS óPTICOS. A presente invenção refere-se ao uso de corantes de ácido esquárico em camadas ópticas para gravação de dados ópticos, de preferência, para gravação de dados ópticos usando um laser com um comprimento de onda de até 450 nm. A invenção refere-se ainda a um meio de gravação de dados óptica do tipo no qual se grava uma vez e se lê várias vezes (WORM), capaz de gravar e reproduzir informações com radiação de laser azul, que emprega um corante de ácido esquárico na camada óptica.
