Abstract

Solid sulphur dyestuff preparations are formed by mixing a sulphur dyestuff with a stable hydrosulphite and a substance of alkaline reaction, with or without further additional substances such as sugar. In examples: (1) calcined sodium carbonate and hydrosulphite FD conc. are mixed with Eclipse yellow RP, Eclipse olive and Eclipse brilliant green 3GT; (2) Eclipse pure blue 3GLP is mixed with sodium carbonate, trisodium phosphate and hydrosulphite FD conc.; (3) Eclipse dark green BP is mixed with sodium glycollate and hydrosulphite FD conc.; (4) Eclipse green GP is mixed with sodium phenate and hydrosulphite FD conc.; glucose may also be added; (5) Eclipse brown B is added to lactose, sodium carbonate and hydrosulphite FD. The use of borax and compounds yielding ammonia is mentioned.
