Abstract
Provided herein is a water-based metallic ink composition specifically adapted for direct digital inkjet printing on non-while fabrics and textile, which affords high resolution, high gloss and high luster metallic effect (high flop index) in decorations and designs that are wash-fast and stretchable. Also provided are processes of using the metallic ink compositions with other colored ink composition in direct digital inkjet printing on textile.
Claims6
A process of printing a metallic element in an image on a substrate, comprising:
- applying on the substrate by a first printhead an aqueous immobilizing composition that comprises a property-adjusting agent,
- digitally applying by a second printhead an aqueous metallic inkjet composition, said aqueous metallic inkjet composition comprises a property-sensitive proto-elastomeric film-forming agent, said property-adjusting agent causes said aqueous metallic inkjet composition to coagulate, and
- digitally applying by a third printhead an aqueous transparent colored inkjet composition on top of said aqueous metallic inkjet composition,
- wherein:
- digitally applying said aqueous transparent colored inkjet composition is effected simultaneously with digitally applying said aqueous metallic inkjet composition;
- said aqueous immobilizing composition is essentially devoid of a film-forming agent;
- and
- said aqueous transparent colored inkjet composition comprises a pigment.
