    摘要: The invention relates to an aqueous cyan inkjet ink composition for use in ink jet printers comprising an aqueous carrier, a self dispersed cyan pigment, a polymeric additive, a surfactant, and a specific cosolvent mixture comprising a C2-C8 terminal alkanediol, a cyclic amide compound and its derivative, a polyol/polyalkylene oxide condensate, and a trihydric alcohol. Preferably, the self dispersed cyan pigment is surface modified with bisphosphonate group. The cyan inkjet ink demonstrates excellent stability, superior chroma, good printhead maintenance characteristics and high heater reliability in permanent and semi permanent printheads.

    摘要: The present invention relates to ink compositions. More particularly, the present invention relates to ink compositions comprising a colorant and a polymeric binder having a below ambient glass transition temperature, an average particle diameter above about 200 nm and an acid component ranging from about 1% to about 10% by weight of the polymeric binder. Additionally, the present invention has the novel and useful feature of resistance to both wet-rub and dry smear as well as increased highlighter resistance and decreased occurrences of maintenance problems such as clogging and kogation.

    摘要: A method of printing uses an inkjet print head to print an ink containing about 0.01 to about 15 wt. % of a wetting agent onto an intermediate transfer surface to form an image on the intermediate transfer surface. The method transfers the image from the intermediate transfer surface to a final medium while the ink is partially wet. The wetting agent may be a 1,2 alkyldiol having 4-10 carbon atoms or a diether alcohol having 6-14 carbon atoms. 1,2 hexanediol and hexylcarbitol, respectively, are particularly suitable wetting agents. If 1,2 hexanediol is used as the wetting agent, the ink may contain about 1.0 to about 5.0 wt. % hexanediol. If hexylcarbitol is used as the wetting agent, the ink may contain about 0.1 to about 2.5 wt. % of hexylcarbitol. The intermediate transfer surface may be coated with a coating solution. In this case, the ink should have a surface energy different from that of the coating solution by no more than about about 10 dynes/cm. The coating solution may contain polyvinyl pyrrolidone, and if so, about 0.01 to about 20 wt. % PVP is suitable. The PVP should have a molecular weight greater than about 400,000.
