Abstract

"COMPOSIçõES DE TONER DE POLIéSTER". A presente invenção refere-se a um toner de poliéster de agregação por emulsão incluindo uma resina de poliéster tendo grupos terminais modificados, em que a resina de poliéster inclui pelo menos um grupo terminal carboxílico. Um processo de produção do toner por meio da oxidação de uma resina de poliéster incluindo a reação do poliéster com um hipoaleto e um catalisador de transferência de fase resulta em uma resina de poliéster terminada com pelo menos um grupo acídico. Uma carga xerográfica estável em todos os ambientes para todas as cores, e excelente resistividade e coesão do toner pode ser obtida.
