PROBLEM TO BE SOLVED: To obtain ink capable of providing colored parts of color filter having good transparency, little bleeding, good adhesive properties and good light- fastness when discharged in ink-jet system by including an auriferous azopyrazolone dye and a dye including a xanthene skeleton. SOLUTION: This ink is obtained by including (A) an auriferous azopyrazolone dye having a structure of formula I (R1 -R4 are each H, a halogen, nitro, a 1-5C alkyl or the like; R5 and R6 are each H, a halogen or the like; M3 is Cr, Ni or Co; X1<+> is a univalent alkali metal cation or the like) and (B) a dye having a xanthene skeleton (a dye including a xanthene skeleton of formula II in a molecule, e.g. a dye of formula III or formula IV). It is preferable that the weight ratio of A:B is (50:1) to (1:2) and the total content of A and B is 0.1-15 wt.% based on total ink weight. |
