Single biphenyl-linked azo dyes replace brown dye mixtures to improve paper lightfastness while preserving brownish shades.

Substituted triazine disazo dyes raise tinctorial strength while preserving UV-Vis characteristics across a broader color range for dyeing and printing.

Combining reactive dyes with complementary fibre-reactive groups improves deep-shade build-up, fixation, wash-off, and wet fastness.

Li+ and Na+ in a reactive black textile ink improve color depth, nozzle recovery, and black hue control across fabrics.

Alkaline-activated reactive dyes bond to leather at pH 8-11, raising fixation and preserving wetfastness, rubfastness, and shade depth.

Alkaline-activable reactive dyes bond covalently to leather at pH 7.5+ to raise fixation and improve wet, perspiration, and rub fastness.

Bridged disazo acid dyes with sulpho groups improve light and wet fastness on polyamide fibers while maintaining strong exhaustion and color consistency.

Na+ and Li+ in a reactive black textile ink improve black hue control, ejection stability, and recovery from nozzle clogging.
