INK FORMULATIONS AND FILM CONSTRUCTIONS THEREOF

摘要

Ink formulations suitable for deposition upon the intermediate transfer member of an indirect printing system and for transfer therefrom to a substrate. The inks are aqueous inkjet inks comprising an organic polymeric resin and a colorant. Ink film constructions including a plurality of continuous ink films fixedly adhered to the printing substrate that can be obtained with these inks are also disclosed. The inks and the printed constructions are such that the ink films and the dried inks composing them have a first dynamic viscosity within a range of 106cP to 5∙107cP at at least a first temperature within a first range of 60°C to 87.5°C, and a second dynamic viscosity of at least 6∙107cP, for at least a second temperature within a second range of 50°C to 55°C.
