    摘要: The invention is directed to amphipathic polymeric particles that serve as both the dispersant and the binder in water based inks, ink compositions containing these particles, and methods for making the particles. The polymeric particles contain both hydrophilic and hydrophobic moieties with a pre-determined structure, and have an average diameter of 50 to 500 nm. The amphipathic polymeric particles may be prepared by a side-chain conversion method or a polymerization process involving an ATRP step, with or without a cross-linking agent. This invention improves the stability of polymer and inks by both ionic and steric stabilization of the suspended polymer particles.

    摘要: A method for stabilizing a dye in an ink comprising the dye and a vehicle is provided. The ink is intended for printing on a print medium, which may comprise a variety of surfaces. The method comprises: (a) providing at least one dye moiety (molecule or monomer); (b) encapsulating the dye moiety in a transparent polymeric matrix to form an encapsulated dye particle that provides a barrier to protect the dye moiety; and (c) incorporating the encapsulated dye particle in the ink. The dye moiety is substantially water-insoluble. Consequently, the method of the present invention enables the use of hydrophobic colorants in a hydrophilic vehicle. A hydrophobic film thus forms on the print medium upon drying.

    摘要: Lightfast additives for inkjet inks are provided. These additives exhibit excellent lightfastness of many dyestuffs (both water-soluble and water-insoluble). The lightfast additives exhibit good water solubility and significant effect on dye and pigment molecules which fade most when exposed to UV, ambient light, etc., and are suitable for improving permanence of inkjet inks, including thermal inkjet ink, piezo inkjet ink, and the like. The lightfast additive comprises a molecule which is composed of three parts or moieties: A—X—B, where (a) moiety A is an aryl sulfonic acid or aryl carboxylic acid, either in acid form or salt form, with or without substituents (e.g., benzene sulfonic acid, naphthalene mono-sulfonic acid, naphthalene di-sulfonic acid, benzoic acid, benzene sulfonic acid sodium salt, and hydroxybenzenesulfonic acid sodium salt), that contributes to the water solubility and compatibility (molecular overlapping) with the dye molecule in the solid state; (b) moiety B is a triazine, benzotriazole, tetrazole, or benzimidazole, with or without substituents, that contributes to improvement of lightfastness of the dye; and (c) moiety X is a connector (—NR— or —O—) between A and B.
