Beschreibung
Zusammenfassung:	Disperse azo and methine dye compositions such as powders and paste containing 0.25 to 4.0 parts weight sodium lignin sulphonate per part of dye are prepared without loss of dye through chemical degradation or the like during processing including grinding and contain 0.10 to 5.0 parts by weight of an ammonium compound e.g. ammonium sulphate. Dyebaths prepared therefrom produce dyeings of exceptionally high colour yield on such fibres as polyester, triacetate, acetate, polyamides, and blends thereof with other natural and synthetic fibres.
