Textile printing using dyes requires different dye classes to be used for different substrates, which increases complexity in the printing operation. The development of a single (universal) class of dyes that can be applied to all fibres to produce prints with excellent technical properties is desirable. Reported is one approach to a universal dye class for printing on multiple substrates. A temporarily water soluble fibre‐reactive dye, 2‐[(4‐{(E)‐[4‐(diethylamino)phenyl]diazenyl}phenyl)sulphonyl]ethyl sodium sulphate, was synthesised and printed on cotton, polyester, polyester/cotton blend, wool, nylon and acrylic fabrics. A print–dry–cure process was employed. Bright, level prints with high colour strength, good rub fastness and fair to good wash fastness were obtained for all substrates except acrylic, which did not produce good prints. However, significant amounts of unfixed dye were removed during soaping.
