摘要： An ink composition includes a dispersion of resin particles in water, a colorant and a co-solvent fraction for stabilizing the dispersion, wherein the co-solvent fraction includes at least one branched polyhydric alcohol and/or at least one (poly)ether modified branched polyhydric alcohol, and between 0.1 and 5 weight % polyvinylpyrrolidone having a weight average molecular weight of at least 5000 g/mol. Such ink compositions show improved robustness on a range of print substrates. In this way robust look and feel films can be realized also on less absorbing media, like the offset coated gloss, silk and matt ones with a better freedom towards recipe variation of e.g. latex and the concentrations of the ingredients.
摘要翻译：油墨组合物包括树脂颗粒在水中的分散体，着色剂和用于稳定分散体的共溶剂部分，其中共溶剂部分包含至少一种支化多元醇和/或至少一种（聚）醚改性的支化多元醇和重量平均分子量为至少5000g / mol的0.1至5重量％的聚乙烯吡咯烷酮。这种油墨组合物在一系列印刷基材上显示出改进的坚固性。以这种方式，也可以在较不吸收的介质上实现稳健的外观和感觉膜，如胶印涂布的光泽，丝绸和无光泽的膜，其具有更好的自由度，例如，胶乳和成分的浓度。

摘要： The present invention relates to an aqueous ink composition having an improved drying and fuse behavior, without compromising the print quality and print robustness. Such an ink composition comprises between 1 and 40 weight% of a water dispersible resin, between 0.5 and 15 weight% of a colorant, between 20 and 80 weight% water and between 1 and 30 weight% of an acetal cosolvent, wherein all amounts are relative to the total ink composition. The ink composition may further comprise between 15 and 75 weight% of a dispersion stabilizing cosolvent.

摘要： The present invention relates to an ink composition suitable for being ejected from an inkjet marking device at an operating temperature. The ink composition comprises a water-dispersible resin and has a dynamic surface tension of below 35 mN/m and a static surface tension of above 21 mN/m both determined at the operating temperature. The ink composition may comprise a mixture of water-soluble organic solvents having a difference in the relative dielectric constant of more than 5, preferably between 10 and 50. The ink composition may comprise a polymeric cosolvent, in particular a polyethylene glycol or polyethylene glycol (di)methyl ether. The ink composition may comprise a mixture of surfactants comprising at least one surfactant of a first type selected from the group consisting of acetylene glycols and ethoxylated acetylene glycols and at least one surfactant of a second type selected from the group consisting of silicone surfactants and fluorochemical surfactants.
