Naphthalene sulphonate is used as dispersants of disperse dyes and also as dispersing and leveling agent of various dyes. It exhibits excellent dyeing ability. Naphthalene sulphonate is also good for improving wetting.
With its excellent dispersing property, a small amount results in good leveling and good impregnation properties of dyes and pigments without any separation.
