Abstract

SE DESCRIBE UN PROCESO PARA LA ELABORACION DE PIGMENTOS DE DESARROLLO DE COLORACION DESDE NEUTRALES HASTA ALCALINOS PARA SU UTILIZACION EN PAPELES DE COPIADO LIBRES DE CARBONO, A PARTIR DE UN SILICATO DE CAPA ESMECTICO ACTIVO ACIDO Y PRODUCTOS QUIMICOS DE REACCION BASICA; EL PROCEDIMIENTO SE CARACTERIZA PORQUE EL SILICATO DE CAPA ACTIVO ACIDO, CUYA ESTRUCTURA DE CAPA ESTA ESENCIALMENTE AUN INTACTA, SIN SECADO TEMPORAL INTERMEDIO, SE UTILIZA CON LOS PRODUCTOS QUIMICOS DE REACCION BASICA HASTA LA CONSTITUCION PARCIAL Y COMPLETA EN LOS BORDES Y EN LAS ESQUINAS DE ACIDO SILICICO AMORFO CONFIGURADO EN CRISTALITA-SILICATO DE CAPA SIN REINTERCAMBIO ESENCIAL O ENTRE LAS CAPAS DE LOS IONES DE HIDRONIO INTRODUCIDOS EN EL SILICATO EN CAPAS MEDIANTE IONES ALCALINOS O ALCALINOTERREOS. LOS PIGMENTOS DE DESARROLLO DE COLORACION PUEDEN SER UTILIZADOS EN SUSPENSIONES CON CONCENTRACIONES DESDE 30 HASTA 50 % EN PESO, CON PREFERENCIA DESDE APROXIMADAMENTE 38 HASTA 48 % EN PESO.
