Abstract

An inkjet ink having an increased shelf life. The inkjet ink comprises an ink vehicle and a reactive colorant. The reactive colorant is nonreactive with water,thereby increasing the shelf life of the inkjet ink to greater than approximately twelve months. An inkjet printing system comprising the inkjet ink and an activating agent is also disclosed. A reactive colorant of the inkjet ink is nonreactive with water but is sufficiently reactive with the activating agent to form an activated complex to fix the reactive colorant to a textile substrate. A method of printing on a textile substrate is also disclosed.
