Abstract

White and coloured reserves under aniline black are produced by printing goods prepared with an aniline black solution with a reserve containing a sparingly volatile, strongly basic organic derivative of ammonia, either alone or in admixture with a suitable vat dyestuff, an alkali carbonate and the reducing agent necessary for fixing the vat dyestuff. Organic derivatives of ammonia specified are: piperazine, diethylethylenediamine and triethanolamine. In examples: (1) a white fabric impregnated with a solution of sodium chloride, sodium ferrocyanide and aniline hydrochloride is printed with a reserve consisting of British gum powder, water and triethanolamine, and is then steamed, oxidized, washed and dried, yielding a white effect on a black ground; (2) the reserve contains in addition Ciba Blue 2BD paste, potassium carbonate and sodium formaldehyde sulphoxylate, whereby a blue effect on a black ground is obtained. Specifications 285,041 and 302,252, [both in Class 15 (ii), Dyeing, Processes &c. for], are referred to.
