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.
