Abstract

LA INVENCION SE REFIERE A UNA DISPOSICION DE ESTRUCTURA CONSISTIENDO EN UNA MULTIPLICIDAD DE ZONAS TENIENDO UN PERFIL DE PROPIEDADES DIFRACTIVAS DADO, EN PARTICULAR PARA UTILIZACION COMO ELEMENTO DE SEGURIDAD IDENTIFICABLES VISUALMENTE SOBRE DOCUMENTOS Y OBJETOS DE VALOR TAL COMO BILLETES DE BANCO, TARJETAS DE CREDITO, PERMISOS Y CHEQUES, ASI COMO PARA OTROS OBJETOS QUE REQUIEREN PROTECCION. PARA MEJORAR UNA DISPOSICION DE ESTRUCTURA DE ESTE TIPO DE TAL FORMA QUE PRESENTE A UN OBSERVADOR UNA IMAGEN PICTORICA QUE ES, EN PARTICULAR, MAS HOMOGENEA Y MAS BRILLANTE DE LO QUE ERA POSIBLE HASTA AHORA EN DISPOSICIONES DE ESTRUCTURA ACTIVAS DE ESTE TIPO, LA INVENCION PROPONE QUE LA MAYORIA DE LAS ZONAS SE DISEÑEN SEGUN UN PERFIL DE BANDAS O CINTAS.
