摘要： This invention relates to a liquid composition adapted to be applied to a recording medium with ink containing a multi-color to form a colored section on the recording medium. The liquid composition contains fine particles reactive relative to the solvent and the coloring material in ink. When processed in particular steps, it produces aggregates of fine particles showing a specific surface area between 70 and 250 m2/g as determined by the BET nitrogen adsorption/desorption method.

摘要： The invention provides colored fine resin particles useful as coloring materials for inks which can provide images having good water fastness, weather fastness and rub-off resistance and are excellent in dispersion stability, and a production process thereof. The colored fine resin particles have a structure in which a pigment coated with a water-insoluble resin is encapsulated with a copolymer composed of at least a polymerizable unsaturated monomer and a reactive emulsifier.
