摘要: Hydroxyethylated polyethyleneimine is added to jet ink having an anionic dye to prevent whisker forming overnight. To avoid excessive viscosity at start-up, the polyethyleneimine is low molecular weight or a low molecular weight hydroxyethylated amine is combined with high molecular weight polyethyleneimine.

摘要: A waterfast ink having 3.0% Food Black 2, 2.5% highly hydroxyethylated polyethyleneimine, 10.0% ammonium benzoate, and the balance water. The invention appears to function upon loss of water after printing by a polar neutralizing between the dye and the polyimine, which results in an affinity of the dye to paper. It is applicable to any dye having anionic solubilizing groups but not having quaternary ammonium and to any ammonium salt.

摘要: An aqueous jet ink of water, dissolved dyes and a surfactant of R--N(C.sub.2 H.sub.4 O).sub.x (C.sub.2 H.sub.4 O).sub.y H, where x+y is from 5 to 25, with x and y each at least 2, and R is alkyl or oxygen containing. The static surface tension is less than 40 dynes/cm while the dynamic surface tension is about 65 dynes/cm. Satellites and splatter in thermal drop on demand printing are greatly reduced, and drop misdirection is reduced.

摘要: Aqueous inks containing 1,2-alkyl of from C4 to C10 diols, specifically 1,2-hexanediol or 1,2-pentanediol are employed in jet inks. Two such inks of different colors applied side-by-side to paper do not bleed and therefore give excellent image definition. The diols are not flammable, odorous or highly volatile.
摘要翻译: 含有C 1 -C 10二醇的1,2-烷基,特别是1,2-己二醇或1,2-戊二醇的水性油墨用于喷墨油墨中。 两种不同颜色的油墨并排涂抹在纸上不会渗色,因此可以提供出色的图像清晰度。 二醇不易燃,无味或易挥发。
