PROBLEM TO BE SOLVED: To develop various red colors that are between orange and magenta color and that can be sensed by a naked eye when being different; and to provide an ink having high quality.SOLUTION: Provided is a light resistance radiation-curable gel ink that includes: at least one curable monomer; at least one organic gelatinizer; at least one photoinitiator; at least one organic pigment; and at least one red pigment. In the light resistance radiation-curable gel ink, the organic pigment is that absorbency is possessed in about 400-about 560 nm of a wavelength region, penetrability is possessed in about 570-about 700 nm of a region, the red pigment is that absorbency is possessed in about 510-about 580 nm of a wavelength region, and penetrability is possessed in about 590-about 700 nm of a region. The gelatinizer is an amide gelatinizer. A radiation ray described here denotes a light ray that has a wave length from ultraviolet to a visible light region, electron beam irradiation or heat or infrared. |
