摘要

Coloring composition (I) of keratinous fibers, comprising an aqueous medium, comprises: a dye (0.001-5 wt.%) (II) carrying an ionic group; and a copolymer block (III) comprising a nonionic hydrosoluble block and an ionic block having charges opposite to that of the ionic charge carried by the dye. An independent claim is also included for a process for coloring of keratinous fiber, comprising the application of (I) on dry or wet fibers and observing for a period followed by optional rinsing of fibers.
