Abstract

La invención divulga un elemento de seguridad reversiblemente piezocrómico para la protección contra la falsificación de documentos de valor, estando caracterizado el elemento de seguridad por que comprende una colección de partículas de pigmento ópticamente contrastantes en una película o una capa de recubrimiento de un polímero elástico. En un modo de realización particular, las partículas son copos de pigmento ópticamente variable, orientados en una posición que es esencialmente diferente de una alineación en el plano de la película o capa de recubrimiento.
