SOLUTION: It is desirable that the hydrophilic groups are bonded to the surfaces of carbon black particles through atomic groups. The atomic group is exemplified by a 1 or 2C linear or branched alkylene, a (substituted) phenylene or a (substituted) naphthylene. The hydrophilic group is exemplified by-COOM,- SO3M,-PO3HM,-SO2NH2, -SO2NHCOR,-NH3+, formula I or formula II. In the formulae, Ms are each independently H, an alkali metal, ammonium or the like; R is a 1-12C alkyl, a (substituted) phenyl or a (substituted) naphthyl. It is desirable that the calcium exists in the form of a calcium ion.

摘要： PROBLEM TO BE SOLVED: To improve feathering resistance and bleeding resistance by sequentially adhering ink on a material to be recorded from ink containing more surfactant in an ink recording method for forming a secondary color image by superposing at least two types of color inks. SOLUTION: When electric signal information is applied to aluminum electrodes 17-1, 17-2 of heads of a multi-head in an ink jet recorder, a region (n) of a heating head 15 is heated, and ink 21 in contact with the region is flowed toward a material 25 to be recorded. In this case, to form a color image by using a plurality of color inks, the plurality of the inks contain surfactants of different contents from each other. When the two types of the color inks are superposed to form a secondary color in, on the material 25, the inks are sequentially stuck on the material 25 from the ink containing more content of the surfactant to form the image.

摘要： PURPOSE:To enable high-grade printing by imparting water resistance to plain paper without exerting adverse effect on an image grade even at the time of printing recording by bonding colorless ink containing a nitrogen compd. represented by a general formula to a material to be recorded before or after bonding ink containing a dye and the liquid medium thereof to the material to be recorded. CONSTITUTION:Colorless ink containing a nitrogen compd. represented by general formula 1 and dye-containing ink are separately bonded to a material to be recorded. In the general formula 1, R1-R4 are a hydrocarbon group which may be substituted with an alkylamino group, a carboxyl group or a group of a salt thereof or a sulfone group or a group of a salt thereof or a hydrogen atom and at least one of them is a 6 or more C hydrocarbon group, n is an integer of 2-4 and m is an integer of 1-99. If both inks are mixed on the material to be recorded, a high-grade image high in water resistance can be obtained without selecting a dye and the stability of ink can be secured. Further, the excessive adhesion of the colorless ink containing the nitrogen compd. represented by the general formula 1 can be also prevented.
