摘要： Problem: To provide a microencapsulated color material for an ink composition which is excellent in dispersion stability, ejection stability and color developability, excellent in fastness and rubbing resistance of images, and hard to cause blurs of images, and can provide recorded matter having high print density; an ink composition using the color material; a production process thereof; an ink jet recording process; recorded matter; and microencapsulated matter.Means for Resolution: A surface of a core material including color material particles such as a pigment is covered with a wall material mainly comprising: 1) a polymer (A) having an ionic group and a hydrophobic group; and 2) a polymer (B) having at least; repeating structural units derived from a first polymerizable surfactant having an ionic group with a charge opposite to the charge of the ionic group of the polymer, a hydrophobic group and a polymerizable group; and repeating structural units derived from a second polymerizable surfactant having a charge of the same kind as or opposite to the charge of the first polymerizable surfactant, and/or a hydrophilic monomer having a charge of the same kind as or opposite to the charge of the ionic group of the polymer and/or a hydrophobic monomer, thereby performing microencapsulation. The color material particles such as the pigment are used as the core material, and a color material obtained by microencapsulating them is allowed to be contained in an aqueous medium to form an ink composition, which is ejected from an ink head onto a recording medium by an ink jet recording process, thereby obtaining recorded matter. By constituting the core material by a pharmaceutical preparation, a metal powder, a ceramic or the like, surface modification of the core material becomes possible.

摘要： Disclosed is a recording liquid including an aqueous pigment dispersion, which has high dispersion stability and high discharge properties and gives a print with superior gloss. Specifically, the aqueous pigment dispersion contains a pigment; a polymer containing cationic monomer structural units and hydrophobic monomer structural units (hydrophobic-group-containing cationic polymer); and a polymer containing anionic monomer structural units and hydrophobic monomer structural units (hydrophobic-group-containing anionic polymer), in which the ratio of the number of anionic groups in the hydrophobic-group-containing anionic polymer to the number of cationic groups in the hydrophobic-group-containing cationic polymer is 1.0 or more and 8 or less. The molar ratio of the hydrophobic monomer structural units to the anionic monomer structural units in the hydrophobic-group-containing anionic polymer is from 5/95 to 50/50 or the content of the pigment is 51 percent by weight or more based on the solids content. This aqueous pigment dispersion is produced by dispersing a pigment with a hydrophobic-group-containing cationic polymer, subsequently subjecting the dispersion to ultrafiltration/microfiltration, and adding a hydrophobic-group-containing anionic polymer thereto.
