| 摘要 |
The invention relates to solid formulations of dyes which are insoluble or sparingly soluble in water, which formulations contain a dialkyl sulfosuccinate having 3 to 8 carbon atoms in each alkyl moiety, or a C3-C6alkylnaphthalenesulfonate and/or a branched or unbranched acetylene glycol containing 8 to 20 carbon atoms, in addition to the dye and one or more anionic dispersants, optionally together with further auxiliaries conventionally employed in powdered formulations. These formulations are characterized by very good wettability, excellent dispersibility and good redispersibility. The dyebaths and padding liquors prepared with these formulation are non-foaming or only low foaming and are in addition stably disperse. They are suitable for dyeing and printing natural and synthetic fibres.
