Die auf der Faser erzeugten unlöslichen Azofarben
A German dye-maker's 1898 trade booklet from Höchst am Main, issued by the Farbwerke vorm. Meister Lucius & Brüning for dyers and textile manufacturers, showing fabric swatches dyed with insoluble azo colours fixed on the fibre. The pictures are mounted cloth samples: a striped maroon and brown fabric with white floral sprigs, plain swatches of deep red and navy, and a busy red, blue and white zigzag pattern that a designer could borrow for textile colour pairings.
