A treatment for pigments is provided. This treatment, which uses certain organosulfonic compounds, imparts improved physical and chemical qualities including lacing resistance, improved dispersion and decreased chemical reactivity when these treated pigments are incorporated into polymeric matrices. The addition of organosulfonic compounds may flexibly be incorporated into known processes at varying points, and are preferably added downstream of any filtering steps.

Um tratamento para pigments é fornecido. Este tratamento, que usa determinados compostos organosulfonic, dá qualidades físicas e químicas melhoradas including a resistência do laço, a dispersão melhorada e o reactivity químico diminuído quando estes pigments tratados são incorporados em matrizes polymeric. A adição de compostos organosulfonic pode flexìvel ser incorporada em processos sabidos em pontos variando, e é adicionada preferivelmente rio abaixo de todas as etapas filtrando.
