Abstract

LA INVENCION SE REFIERE A UN PORTADOR DE DATOS O TARJETA ANALIZADORA; QUE SE PROTEGE CONTRA ADULTERACIONES A TRAVES DE UNA COPIADORA CROMATICA Y CONTIENE UN ELEMENTO DE SEGURIDAD OPTICO VARIABLE EN MATERIAL FLUIDO-CRISTALINO Y SE CARACTERIZA PORQUE; EL ELEMENTO DE SEGURIDAD PRESENTA UNA CAPA DE MATERIAL A BASE DE POLIMERO FLUIDO-CRISTALINO QUE MUESTRA A TEMPERATURA AMBIENTE UN ESPEJO DE CAMBIO DE COLOR Y PUEDE FABRICARSE DIFERENTES ELEMENTOS DE SEGURIDAD, YA QUE LOS MATERIALES FLUIDO-CRISTALINO POSIBILITAN UNA LIGERA ELABORACION DEL PRODUCTO ACABADO.THE INVENTION REFERS TO A DATA CARRIER OR ANALYZER CARD; THAT IT PROTECTS AGAINST ADULTERATIONS THROUGH A CHROMATIC COPIER AND CONTAINS A VARIABLE OPTICAL SAFETY ELEMENT IN FLUID-CRYSTALLINE MATERIAL AND IS CHARACTERIZED BECAUSE; THE SAFETY ELEMENT PRESENTS A LAYER OF FLUID-CRYSTALLINE POLYMER BASED MATERIAL THAT SHOWS AT ROOM TEMPERATURE A COLOR CHANGING MIRROR AND MAY BE MADE OF DIFFERENT SAFETY ELEMENTS, AS THEY MAKE IT POSSIBLE TO PRODUCE A FLUID-CRYSTALLINE MATERIAL.
