    • The present invention provides a durable, external surfactant free, cationic, water based jet ink polymer which when formulated into an ink jet ink results in a printing that has an excellent adhesion to metal or plastic substrates. Such a jet ink polymer is suitable performance replacement of solvent soluble polymers currently in commercial use. The hybridized copolymer comprises a hydrophobic functional polymeric backbone comprised of a polysiloxane polymer, a polyolefin polymer, or a functional polyvinyl polymer. The hybridized copolymer also comprises a plurality of copolymeric side chains attached to the backbone, comprising a polymerizable amine-containing unsaturated monomer, and a polymerizable unsaturated monomer. The use of the inks of the present invention enhances performance criteria such as print-head open time, ink stability, and resistance to typical water based cleaners.
    • 本发明提供了耐久的外部表面活性剂,阳离子型水基喷墨油墨聚合物,其在配制成喷墨油墨时形成与金属或塑料基材具有优异粘附性的印刷。 这种喷墨油墨聚合物是目前商业上使用的溶剂可溶性聚合物的合适的性能替代品。 杂化共聚物包含由聚硅氧烷聚合物,聚烯烃聚合物或官能聚乙烯基聚合物组成的疏水官能聚合物主链。 杂化共聚物还包括连接到主链上的多个共聚侧链,包含可聚合的含胺不饱和单体和可聚合的不饱和单体。 使用本发明的油墨增强了性能标准,例如打印头打开时间,油墨稳定性和对典型的水基清洁剂的耐受性。
