Abstract

La invención se refiere a un cuerpo de lámina (1) de varias capas para marcar un documento de seguridad, en particular un billete de banco. El cuerpo de lámina (1) tiene al menos una capa de filtro de color (2) y al menos una capa de cambio (4) con una transmitancia eléctricamente controlable y/o un color eléctricamente controlable. La capa de cambio (4) puede tener cristales líquidos (15) los cuales se pueden alinear en un campo eléctrico, tal como una capa de PDLC. El cuerpo de lámina (1) de preferencia comprende dos capas de filtro de color (2, 3), de diferentes colores y una capa de cambio (4) la cual se dispone entre las mismas. La invención además se refiere a un elemento de seguridad (10) que tiene al menos un cuerpo de lámina antes mencionado y una fuente de energía piezoeléctrica (8) que controla la capa de cambio (4).
