Abstract

"TONER CONTENDO PARTìCULAS DE ARGILA DE SILICATO PARA SENSIBILIDADE MELHORADA à UMIDADE RELATIVA". A presente invenção refere-se a partículas de toner, preferivelmente partículas de toner de agregação de emulsão, que têm sensibilidade à umidade relativa melhorada através da inclusão nela das partículas da argila de silicato tal como argila de caulim. As partículas de toner incluem um aglutinante, preferivelmente um aglutinante contendo acrilato, pelo menos uma substância corante e partículas de argila de silicato distribuídas no aglutinante. Em uma modalidade de revestimento do núcleo, as partículas de silicato são distribuídas no núcleo, na camada de revestimento ou ambos. Reveladores do toner em combinação com partículas portadoras são também descritos.
