Abstract
La presente invencion describe el uso de agentes blanqueadores para aumentar la brillantez de papel rellenado. En el procedimiento de la presente invencion, el papel rellenado se trata con agentes blanqueadores durante el procedimiento de fabricacion de papel. El procedimiento puede utilizarse en todas las clases de papel que contienen rellenador. Sin embargo, la presente invencion es particularmenteutil en clases de papel de baja brillantez que se producen a partir de pulpas mecánicas y contienen un carbonato de calcio.
