Abstract
Reactive ink compositions of the present invention utilize at least two reactive components, a base ink component and a curing component, that are applied to a receiving substrate separately. The base ink component includes an ink carrier, a compatible colorant, and a cross-linkable constituent, and the curing component is a cross-linking agent. Upon exposure of the base ink component to the curing component, at least a portion of the ink is cross-linked to provide a printed image that is durable and abrasion-resistant.
Claims21
A reactive ink system for use in ink jet printers comprising:
- a base ink component having an ink carrier, a compatible colorant, and a cross-linkable constituent;
- and
- a cross-linking agent reactive with the cross-linkable constituent in the base ink component;
- and
- a substrate support surface;
- means for applying cross-linking agent on the substrate support surface;
- means for applying a predetermined pattern of the base ink component on the substrate support surface after the cross-linking agent has been applied on the substrate support surface to create a cross-linked ink pattern, and
- means for placing a substrate in contact with the substrate support surface to transfer the cross-linked ink pattern to the substrate from the substrate support surface.
A reactive ink system according to claim wherein the cross-linking agent is selected from the group consisting of diethylene triamine;
- 1,3-pentanediamine;
- 1,6-hexandiamine;
- polyoxypropylenediamine;
- polyethylene glycol;
- and glycerol.
