Abstract
DOCUMENTOS DE SEGURANÇA OU ARTIGOS QUE COMPREENDEM CAMADAS DE EFEITO ÓPTICO QUE COMPREENDEM PARTÍCULAS DE PIGMENTO MAGNÉTICAS OU MAGNETIZÁVEIS E MÉTODOS PARA PRODUZIR AS DITAS CAMADAS DE EFEITO ÓPTICO. A invenção se refere ao campo da proteção de documentos de segurança como, por exemplo, cédulas bancárias e documentos de identidade contra falsificação e reprodução ilegal. Em particular, a presente invenção fornece documentos de segurança e artigos decorativos que compreendem uma ou mais camadas de efeito óptico (OELs) e métodos para produzir as ditas OELs, sendo que as ditas OELs compreendem partículas de pigmento magnéticas ou magnetizáveis em formato de plaqueta orientadas magneticamente em uma camada de revestimento pelo menos parcialmente curada (x10) e que exibe um efeito óptico chamativo, permitindo, assim, que um observador autentique facilmente as ditas OELs mediante a inclinação em ângulos de visão/observação entre cerca de -45° e cerca de +45°.
