Abstract

COMPOSIçõES DE TONER. Toners de componente simples tendo um núcleo com um primeiro látex tendo uma temperatura de transição vítrea e peso molecular específicos, ulteriormente tendo um revestimento que envolve o núcleo com um segundo látex tendo uma temperatura de transição vítrea e peso molecular específicos, e aditivos adicionados aos mesmos, e processos para a produção dos mesmos. Em concretizações, o toner é um componente de toner simples não magnético produzido por métodos de agregação de emulsão.
