Abstract

El presente se refiere al campo de la protección de documentos de seguridad tales como, por ejemplo, billetes de papel moneda y documentos de identidad, contra la falsificación y la reproducción ilegal. En particular, el presente se refiere a capas de efectos ópticos (OEL) que muestran un efecto óptico que depende del ángulo de visión, a dispositivos y procesos para la producción de las mencionadas OEL y a artículos que llevan las mencionadas OEL, así como a usos de las mencionadas capas de efectos ópticos en carácter de medios para evitar la falsificación de documentos. La OEL consta de una pluralidad de partículas magnéticas o magnetizables no esféricas que se hallan dispersas en una composición de revestimiento que consta de un material ligante, comprendiendo la OEL dos o más zonas en forma de bucle que están encajadas en tomo de una zona central en común que está rodeada por la zona más interna en forma de bucle, en la que, en cada una de las zonas en forma de bucle, parte, cuando menos, de la pluralidad de partículas magnéticas o magnetizables no esféricas se orienta de manera tal que en una sección transversal perpendicular a la capa de OEL y extendiéndose desde el centro de la zona central hasta el límite exterior de la zona más exterior en forma de bucle, el eje más largo de las partículas orientadas que hay en cada una de las zonas en sección transversal de las zonas en forma de bucle, sigue una tangente a, o bien a una parte con curvatura en sentido negativo, o bien a una parte con curvatura en sentido positivo, de una elipse o de un círculo hipotéticos.
