Beschreibung

Direct blue 76 is a dye that is used in textile printing and other applications. Direct blue 76 is an organic solvent-based dye with a hydrocarbon group. It can be activated by acid, alkali, and heat. Direct blue 76 has been shown to be reactive with metal ions such as copper and zinc. The reaction solution for this dye consists of 2-methyl-4-isothiazolin-3-one, silicone, surfactant, and polymerization initiator. This dye has a viscosity of 0.2-0.6 mPa·s at 25 °C and an activation energy of 11-12 kJ/mol.
