Abstract
A coating composition for an image transfer member in an aqueous ink imaging system is disclosed that comprises a hydrophilic composition and a surfactant. The hydrophilic composition can be a starch-based composition.
Claims20
A coating composition for an image transfer member in an aqueous ink imaging system in which the aqueous ink includes a colorant in a liquid solvent, comprising:
- a hydrophilic composition including an absorption agent in a liquid carrier, the absorption agent adapted to absorb the solvent in the aqueous ink and to be substantially impermeable to the colorant in the aqueous ink when the hydrophilic composition is dried;
- and
- a surfactant.
An aqueous ink transfer process comprising:
- coating the surface of an image transfer member (ITM) with a coating composition to a first thickness, the coating composition including a hydrophilic composition and a surfactant, wherein the hydrophilic composition includes an absorption agent in a liquid carrier, the absorption agent adapted to absorb the solvent in the aqueous ink;
- partially drying the coating composition to a reduced second thickness;
- applying aqueous ink onto the coating composition in which the aqueous ink includes a colorant in a liquid solvent;
- swelling the coating composition by absorbing water from the ink;
- partially drying the ink;
- and
- transferring the ink onto a substrate.
