れている。2. Description of the Related Art The mainstream of ink applied to an ink jet system is composed of a water-soluble dye and its solvent. When actual printing is performed mainly with ink containing a water-soluble dye, ink bleeds on the transfer medium and high-quality printing cannot be obtained, and the color tone of the formed recorded image is unclear and the density is low. The recorded image thus obtained has drawbacks such as poor water resistance and light resistance. Therefore, recently, in order to improve the water resistance and light resistance of a recorded image, which is one of the problems of the ink containing mainly the water-soluble dye, an attempt has been made to apply a pigment-based ink to an inkjet recording method.
