Abstract

DISPOSITIVOS óPTICOS ANISOTRóPICOS E MéTODO PARA PRODUçãO DO MESMO. A presente invenção refere-se a um componente óptico compreendendo um difusor anisotrópico (5, 10), com anisotropia padronizada, e um meio (9, 11, 14,16, 17, 20, 21, 30, 32) para proporcionar uma variação de cor, observável por variação do ângulo de visualização (6) e/ou variação do ângulo de luz incidente (2). Refere-se também a métodos para produção desse componente óptico e a usos desses componentes ópticos, como elementos de segurança com um nível de segurança muito alto.
