The hyperbranched polyglycerol, (BPG), was synthesized through anionic ring-opening polymerization from glycidol using 1-butanol as the starting material. The branched structure of BPG is presented and described. The presence of linear, dendritic and terminal units was confirmed by Moore et al. (Prog Surf Sci 88(3):213–236, 2013) 13C NMR spectroscopy. BPG was then used as a performance additive in a water-based flexographic printing ink. The impact of a small amount of hyperbranched BPG on the printing ink color was examined by studying the optical density of a full-tone area, the total color difference, ΔE ab *, and the gloss of the dried ink film. The colorfastness to dry and wet rubbing of overprinted samples was studied. The investigated BPG is shown to be able to improve colorfastness to dry and wet rubbing of prints.

Ionic liquids as performance additives for water-based printing inks / Zuzanna Zolek-Tryznowska in COLORATION TECHNOLOGY, Vol. 130, N° 4 (08/2014)

The aim of this work was to study the influence of ionic liquids on the selected properties of water-based printing ink and the prints. The contact angles of the printing inks on the printing base were measured. Modified flexographic inks were laboratory printed on polypropylene plastic film. The impact of small amounts of various ionic liquids on printing ink colour was examined in terms of the optical density of the full-tone area, the colour parameters (L*, a*, b*, CIE), the total colour difference, and the gloss of the dried ink film. The influence of ionic liquids on the ink contact angle, the optical density, and the L*a*b* coordinates is discussed. In general, the investigated ionic liquids improve the wettability of water-based flexographic printing ink, with an acceptable total colour difference. The optical density is increased for printing inks containing ionic liquids in comparison with the original flexographic printing ink, Process.

The wettability effect of branched polyglycerols used as performance additives for water-based printing inks / Mariusz Tryznowski in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 15, N° 3 (05/2018)

Langues : Américain (ame) Catégories : Encre -- Additifs Encre en phase aqueuse Encre flexographique Mouillabilité Polyglycérol Polymères -- Synthèse Index. décimale : 667.9 Revêtements et enduits Résumé : The aim of this work was to study the influence of primary and secondary hydroxyl groups in the branched polyglycerol on the selected properties of water-based printing ink and copies printed with water-based flexographic printing inks. The branched polyglycerols were synthesized through anionic ring-opening polymerization using trimethylolpropane as a starting material. Obtained polyglycerol exhibited an irregular structure containing primary and secondary or predominantly primary hydroxyl groups in the macromolecule. The analysis (FTIR, 1H NMR, 13C NMR) confirmed the structure of polyglycerols. Obtained polyglycerols were then used as a performance additive in a water-based flexographic printing ink. The contact angles of the printing inks on the printing base were measured. The impact of a small amount of branched polyglycerol on the printing ink color was examined by studying the optical density of a full-tone area, the color values (CIELAB), the total color difference \(\Delta E_{ab}^{*}\), and gloss of the dried ink film. In general, the addition of branched polyglycerol containing only primary hydroxyl groups improved the wettability of the plastic film and gloss of printing ink with an acceptable total color difference \(\Delta E_{ab}^{*}\) in contrast to branched polyglycerol with primary and secondary hydroxyl groups.
