Abstract

La invención se refiere al campo de la protección de documentos de seguridad como, por ejemplo, billetes de banco y documentos identificativos, para combatir la falsificación y la reproducción ilegal. En particular, la presente invención proporciona documentos y artículos decorativos de seguridad que comprenden una o más capas de efecto óptico (OEL) y métodos para producir dichas OEL, comprendiendo dichas OEL partículas de pigmento magnéticas o magnetizables en forma de plaqueta orientadas magnéticamente en una capa de revestimiento al menos parcialmente curada (x10) y que exhiben un efecto óptico llamativo, lo que permite de este modo a un observador autentificar fácilmente dichas OEL al inclinarlas en ángulos de visión/observación de entre aproximadamente -45° y aproximadamente +45°.
