Anionic dye composition.

摘要

To produce a dye composition comprising an anionic dye sequestered with a specified quaternary ammonium compound and an anionic surfactant and to dye polyamide fibers, cellulose fibers and fibrous materials comprising them with the dye composition. The dyeing properties of anionic dyes which have been a problem in the art can be remarkably improved and excellent levelness and penetrability can be obtained by sequestering an anionic dye such as an acid dye, reactive dye or direct dye and dispersing it with an anionic surfactant.
