Abstract

Um pigmento deslaminado e desenlameado é expandido com quantidades pequenas e controladas de um polieletrólito catiónico, como cloreto de polidimetildialil amónio, para produzir um pigmento altamente expandido, ideal para melhorar a imprimibilidade, a opacidade e o lustro da folha em aplicações de papel revestido, particularmente em papéis LWC para rotogravura.
