Abstract
Novel inkjet ink compositions for forming an image in a form of an elastic film attached to a surface of a stretchable and/or flexible substrate and processes utilizing same for inkjet printing color images on various substrates such as colored and absorptive or impregnable stretchable materials, which are characterized by heightened efficiency in process time, ink and energy consumption, as well as products having durable, wash-fast and abrasion-fast images printed thereon by the process, are disclosed. The novel ink compositions comprise a first part, which contains a property-adjusting agent and a carrier, and a second part which contains an emulsified property-sensitive proto-elastomeric film-forming agent, a colorant and a carrier, such that the second part congeals upon contact with the property-adjusting agent. The second part is digitally applied to the substrate less than 1 second following the application of the first part to the substrate.
