Abstract

LA INVENCION SE REFIERE A UNA CAPA CONTENIENDO MICROCAPSULAS CON COLORANTES LEUCO DISUELTOS EN ACEITE DE NUCLEO, COLOCADOS SOBRE LA CARA INFERIOR DE PAPEL DE AUTOCOPIA SENSIBLE A LA PRESION. PARA PREVENIR QUE EL ACEITE DE NUCLEO SE FUNDA A TRAVES DEL PAPEL SOPORTE, ESTE PAPEL SOPORTE CONTIENE UNA BARRERA DE ACEITE CON UN VALOR DE ABSORCION EN ACEITE INFERIOR A 10 G/M2, MEDIDO UTILIZANDO EL METODO COBB-UNGER, Y EL EXTRACTO DE AGUA CALIENTE DISPONE DE UN VALOR DE PH DESDE 7,5 HASTA 9,5. LA BARRERA DE ACEITE CONSISTE EN UNA IMPREGNACION ELABORADA DENTRO DE LA MASA DEL PAPEL SOPORTE O UNA PREPARACION DE SUPERFICIE REPELENTE DE ACEITE DE HIDROCOLOIDES FORMANDO UNA PELICULA, DISPERSIONES PLASTICAS, PIGMENTOS O MEZCLAS DE ELLOS APLICADOS SOBRE UNO O AMBOS LADOS DEL PAPEL.THE INVENTION REFERS TO A LAYER CONTAINING MICROCAPSULES WITH LEUCO DYES DISSOLVED IN NUCLEUS OIL, PLACED ON THE BOTTOM FACE OF PRESSURE SENSITIVE AUTOCOPY PAPER. TO PREVENT THE CORE OIL FROM MELTING THROUGH THE SUPPORT PAPER, THIS SUPPORT PAPER CONTAINS AN OIL BARRIER WITH AN OIL ABSORPTION VALUE LESS THAN 10 G / M2, MEASURED USING THE COBB-UNGER METHOD, AND THE EXTRACT OF AQUA HOT HAS A PH VALUE FROM 7.5 TO 9.5. THE OIL BARRIER CONSISTS OF A PREPARATION IMPREGNATED WITHIN THE MASS OF THE PAPER SUPPORT OR A PREPARATION OF A REPELLENT SURFACE OF HYDROCOLOID OIL FORMING A FILM, PLASTIC DISPERSIONS OF THEM.
