Key Features of Rapid Dyes

• Applied to the fiber in one operation.
• When developed under acid condition bright full shades are obtained which possess very good fastness properties.
• Due to cross coupling which may occur between certain Rapid Fasts, proper care should be taken when using mixtures of Rapid Fast as resultant shade obtained is un-predictable.
• Dyestuffs of others groups may be used to supplement the color range, particularly for greens and blues.
• As the Rapid Fast can be developed by either neutral or Acid ageing colors of Rapid Fast vat or Rapid Sols may be printed alongside.
• In some cases Rapid Sols can also be printed in admixture with Rapid Fast
