Abstract

Se presenta una forma mejorada de carbonato de calcio resistente al ácido para facilitar su uso como material de aportación para producir papel neutro alevemente ácido, y un proceso para producir este carbonato de calcio resistente al ácido. Este carbonato de calcio resistente al ácido comprende carbonato decalcio en mezcla con por lo menos 0,5 a 10 por ciento, en base al peso seco del carbonato de calcio, de un sal catiónica, junto con por lo menos 0,5 a 10 porciento, en base al peso seco delcarbonato de calcio, de una sal aniónica. Se presenta además un método para mejorar las propiedades ópticas de papel neutroa levemente ácido mediante la adición al mismo de dicho carbonato de calcio así como un papel neutro al ácido que comprendeel carbonato de calcio.
