Abstract

"ESTRUTURA DE GRADE MICRO-óTICA, MéTODO PARA PRODUZIR A MESMA, E, PRODUTO CONTENDO UM OU DIVERSOS EFEITOS VISUAIS, HOLOGRáFICOS OU CORRESPONDENTES". A invenção refere-se a uma estrutura de grade (G) micro-ótica formada sobre um substrato (S) que é, de preferência, produzida como uma estrutura de grade superficial. A invenção refere-se também a um método para produzir a mencionada estrutura de grade. Além disso, a invenção refere-se a um produto que compreende uma ou diversas áreas de padrão (A, B, C, D), cujas áreas de padrão único são formadas por meio da estrutura de grade de acordo com a invenção. De acordo com a invenção, a estrutura de grade (G) é arranjada para produzir para um observador um efeito visual holográfico ou correspondente baseado na difração da luz pelo direcionamento da luz difratada proveniente da estrutura de grade e correspondente ao comprimento de onda de projeto (sym) substancialmente para apenas umas poucas ordens de difração (m). Ordem de difração única, desse modo, corresponde a uma certa direção de observação do efeito visual observado sobre o mencionado comprimento de onda de projeto. De acordo com a invenção, a estrutura de grade é arranjada para deixar uma faixa livre de ângulos entre direções de observação adjacentes, de modo que a estrutura de grade (G) sendo examinada de direções correspondentes à mencionada faixa de ângulos não produza, para o observador, um efeito claramente observável baseado na difração, a mencionada estrutura de grade sendo, assim substancialmente transparente. A invenção é adequada para produzir efeitos visuais que são transparentes no modo acima descrito, mas, ao mesmo tempo, claramente visíveis nas direções de observação, por exemplo, sobre os substratos transparentes como estes.
