Abstract

SE DESCRIBE UNA COMPOSICION DE REVESTIMIENTO QUE COMPRENDE UN LIGANTE DE RESINA POLIMERICA Y COPOS DE PIGMENTO OPTICAMENTE VARIABLE EN CAPA FINA. LOS COPOS DE PIGMENTO TIENEN UNA ESTRUCTURA DE INTERFERENCIA EN MULTICAPA DE LAMINA FINA QUE COMPRENDE UNA CAPA DE METAL REFLECTANTE CON UNA PRIMERA Y SEGUNDA SUPERFICIES PLANAS Y PARALELAS, Y, DISPUESTA EN AL MENOS UNA DE DICHAS PRIMERA Y SEGUNDA SUPERFICIES PLANAS Y PARALELAS, AL MENOS UNA CAPA TRANSPARENTE DIELECTRICA. LOS COPOS DE PIGMENTO TIENEN UN TAMAÑO MEDIO DE PARTICULA DE 5 A 40 {MI}M Y UNA DISTRIBUCION EN EL TAMAÑO DE LAS PARTICULAS DONDE NO MAS DEL 10 % DE LAS PARTICULAS TIENE UN TAMAÑO MAYOR 50 {MI}M, Y BASICAMENTE NINGUNA DE LAS PARTICULAS TIENE UN TAMAÑO DE 125 {MI}M. ESTA COMPOSICION DE REVESTIMIENTO SE PUEDE UTILIZAR PARA PREPARAR UNA VARIEDAD DE REVESTIMIENTOS, ESPECIALMENTE COMPOSICIONES COMPUESTAS DE COLOR MAS CLARO TALES COMO LAS QUE SE UTILIZAN EN LA INDUSTRIA DEL AUTOMOVIL
