Abstract
A pigment-based ink composition for ink jet recording is provided which can offer prints having excellent scratch resistance and free from uneven printing. Ink jet recording is carried out using an ink composition comprising a pigment and an inorganic oxide colloid in combination. Further, the use of a recording head equipped with a nozzle plate (,), which has been treated to form a fluoropolymer-containing plating layer (,) thereon for rendering the nozzle plate (,) water-repellent, can realize printing free from the ejection of ink droplets with trajectories non-perpendicular to the print head.
