发明名称 Ink set and ink cartridge and recording method, recording material and recording apparatus
摘要 The present invention provides an ink set and ink cartridge which allow color printing of an image having an excellent color reproduction with a plurality of inks using an ink jet recording apparatus and provide a good discoloration resistance, color developability and water fastness, a recording method using the ink set and ink cartridge, a recorded material thus obtained, and a recording apparatus therefor. The ink set according to the invention is an "ink set comprising a dye ink and a pigment ink in combination, characterized in that there are contained a plurality of inks having the same hue but different densities for at least one hue and at least one of the inks having a low density comprises a pigment incorporated therein as a colorant". Thus, the use of an "ink having a low density (light-colored ink)" comprising a pigment incorporated therein as a colorant makes it possible to provide improvements in properties such as light fastness and water fastness in a low image density range (highlight range) in particular. Further, the ink cartridge, recording method, recorded material thus obtained, and recording apparatus therefor according to the invention are characterized by the use of the foregoing ink set.
