Abstract

La invención se relaciona al campo de la protección de documentos de seguridad tal como por ejemplo notas bancarias y documentos de identidad contra falsificación y reproducción ilegal. En particular, la invención se refiere a capas de efecto óptico (OEL) que muestran un efecto óptico dependiente del ángulo de visión, dispositivos y procesos para producir OEL y artículos que tienen OEL, así como usos de estas capas de efecto óptico como un medio anti-falsificación en los documentos. Las OEL comprenden una pluralidad de las partículas magnéticas o magnetizables no esféricas, que están dispersadas en una composición de revestimiento que comprende una material de barrera, en donde en al menos un área en forma de bucle de las OEL, al menos una parte de las partículas magnéticas o magnetizables no esféricas están orientadas tal que su eje más largo esté sustancialmente paralelo al plano de las OEL, y en donde, en la sección transversal perpendicular a las OEL y que se extiende desde el centro del área central, el eje más largo de las partículas orientadas presenten en el área en forma de bucle que forma la impresión del cuerpo en forma de bucle siguen una tangente de ya sea la parte negativamente curveada o positivamente curveada de un círculo o elipse hipotética.
