PURPOSE:To obtain a color filter satisfying the accuracy of an impact area of an ink droplet at the time of jetting out of an ink jet head, the transparency of a colored part (pixel), bleeding and light resistance by specifying a dye included in the ink. CONSTITUTION:The ink includes at least the dye expressed by formula I. In formula 1, R<1> represents H or -CH3, R<2> represents H or a compound expressed by formula II or formula III, R<3> represent H, -CH3, -NHCOCH3, -N(CH3)COCH3, -SO3M or a compound expressed by formula IV, R<4> represents H, -COOC2H5, -SO2CH2CH2OSO3Na or a compound expressed by formula V, R<5> represents H, -CH3 or -SO3M, R<6> represents -CH3, -OH, -NO2, -SO3M or -COOM, M represents an alkali metal, an ammonium or an organic amonium, (j) represents integers of 1-3, (k) is integers of 0-1, (m) is integers of 0-2. And the concn. of the dye in the ink is 0.1-15wt.% and the ink contains 5-50wt.% solvent having 150-250 deg.C b.p. |
