Abstract

La invención se refiere al campo de la protección de documentos de seguridad tales como, por ejemplo, billetes de banco y documentos identificativos, para combatir la falsificación y la reproducción ilegal. En particular, la presente invención proporciona métodos para producir capas de efecto óptico (OEL) que muestran una o más marcas (x30) en un sustrato (x20), comprendiendo dicho método una etapa de exponer una capa de recubrimiento (x10) que comprende partículas de pigmento magnéticas o magnetizables no esféricas a un campo magnético de un dispositivo de generación de campos magnéticos para orientar al menos una parte de las partículas de pigmento magnéticas o magnetizables; una etapa de aplicar una composición de recubrimiento superior en la parte superior de la capa de recubrimiento (x10) y en la forma de una o más marcas (x30), y una etapa de curar, al menos parcialmente, la capa de recubrimiento (x10) y la una o más marcas (x30) con una unidad de curado (x50).
