Application of the benzidine colours in all branches of printing
A dyestuff manufacturer's sample book issued by Farbenfabriken Bayer at Elberfeld in 1898, showing printers and textile works how benzidine direct colours behaved on cloth. Mounted fabric swatches carry stripes, chain and dash motifs, and scattered dot patterns in maroon, rust, violet and green, offering woven textures, repeating small-scale patterns and a dated industrial dye palette.
