Abstract

Preparations for dyeing comprise one or more arylides of b -hydroxynaphthoic acid and/or one or more acetoacetic arylides and sodium metasilicate or mixtures thereof with small proportions of other alkaline-reacting salts such as soda-ash or trisodium phosphate, or aqueous solutions of these ingredients. In examples, sodium metasilicate in powder or finely crystalline form is intimately mixed, e.g. in a horizontal mixing drum, with: (1) "Brenthol" (Registered Trade Mark) MN Powder; (2) "Brenthol" OT Powder; (3) "Brenthol" AT Powder and trisodium phosphate; (4) "Brenthol" OT Powder and sodaash; (5) "Brenthol" OT Powder and "Brenthol" AT Powder. Specification 474,638 is referred to.
