Abstract

"FILMES REFLETIVOS DE LIGA DE PRATA (AG) E MEIOS DE REGISTRO DE INFORMAçãO óTICA". A presente invenção refere-se a um filme refletivo de liga de prata, o qual contém X1 como componente e apresenta uma camada enriquecida localizada numa região com uma profundidade de 2 nm a partir da superfície do filme refletivo, em que o componente X1 é enriquecido na camada enriquecida com uma concentração mais alta do que a concentração média de X1 em todo o filme relfetivo, em que X1 é pelo menos um elemento formador de liga, selecionado do grupo que consiste de Bi, Si, Ge, Pb, Zn, Cd, Hg, Al, Ga, In, Tl, Sn, As e Sb. O filme refletivo apresenta propriedades básicas estáveis e excelentes na condição de filme refletivo, tais como, refletividade inicial e durabilidade, satisfazendo ainda a certas exigências, como a de uma adequada gravação com laser. Um meio de registro de informação ótica inclui o filme refletivo, sendo considerado como excelente.
