摘要:
Aqueous ink jet ink compositions are used for ink jet printing colorless, colored or invisible images on receiver elements. These compositions contain a dispersion of an unsaturated natural oil and a water compatible polyurethane. The unsaturated oil dispersion is prepared from conventional surfactants or a polyurethane dispersing agent. The polyurethane is prepared from unsaturated polyol segments prepared from the unsaturated natural oils. The ink preparations are printed on media treated with agents such as metal ions known to catalyze crosslinking reactions in unsaturated oils. Such compositions are useful in various ink jet printing systems including drop on demand and continuous ink jet printing systems.

An inkjet ink which is reduced in system load and is superior in continuous ejection stability, high aptitude for plain paper and excellent in text quality, fixability and image texture is disclosed, comprising an unsaturated fatty acid ester, a compound capable of allowing an ink composition to reversibly gel in an amount of 0.5 to 20% by mass, based on total mass of the ink, and a resin in an amount of 10 to 30% by mass, based on total mass of the ink, and an inkjet image forming method is also disclosed.
摘要:
A water-in-oil (W/O) emulsion ink which is suitable for use in inkjet printing and superior in ejection performance and storage stability is provided. A polyglycerin fatty acid ester which fatty acid moiety is oleic acid or isostearic acid and which has an HLB value of 7-14, is used as an emulsifier. The polyglycerin fatty acid ester preferably has a glycerin polymerization degree of 4-20 and preferably contains 1-3 fatty acids per one molecule thereof. The polyglycerin fatty acid ester has an organic value of preferably 550-2300 and an inorganic value of preferably 600-2500. Preferably, the emulsion ink comprises 40-99 mass % of the oil phase and 60-1 mass % of the water phase, and comprises 0.5-40 mass % of the polyglycerin fatty acid ester relative to the total amount of the ink. The water phase may contain a dye and optionally a solubilizer such as an amine based surfactant.

The present invention relates to coarse calcined kaolin slurries having a high solids content. The invention also relates to methods of making such slurries. The resulting slurries can have a solids content of at least about 58% by weight wherein at least about 40% by weight of the calcined kaolin particles has a particle size of at least about 1 μm. The slurries can be stabilized where the solids show little settling from suspension. The slurries have many uses, including fillers or extenders in paint and coating compositions for paper or paper board. More generally, the inventive products may be used wherever calcined kaolins are used. The present invention also related to coarse calcined kaolin slurries having a multimodal particle size distribution and a high solids content.
