Abstract

Procedure for composing dye preparations low in salt, liquids and concentrates, characterized by passing once or several times, under pressure, saline solutions or suspensions of dyes or optical lighteners through a semipermeable membrane that leaves water and molecular weight substances free. low dissolved in it, while retaining dissolved or finely dispersed optical dyes.
