Abstract: A novel ink is provided which comprises a metal complex azopyrazolone dye and a xanthene dye. This ink is suitable for forming a color filter by an ink-jet system. A color filter, a liquid crystal panel, and a computer employing the ink are also provided. Further, a process for producing the color filter is provided.

Abstract: An ink comprising water, a water-dissipatable polymer and a dye of the Formula (1): wherein: R1 is optionally substituted alkyl or optionally substituted aryl; R2 is H, optionally substituted alkyl or optionally substituted aryl; R5 is H or optionally substituted alkyl; and R3 and R4 are each independently optionally substituted alkyl or optionally substituted aryl, or R3 and R4 together with the CH group to which they are attached from an optionally substituted 5- or 6- membered ring. Also claimed are dyes and ink jet printing processes.

Abstract: A jet printing ink contains an azo dye of the formula (I): wherein X1 is ═N— or ═CR4—; Y1 is —N═ or —CR5═; Z1 is —S—, —NR6— or —N═CR7— in which the right end of each group connects to Y1; the benzene ring A can have a substituent; each of R1, R2 and R6 is hydrogen, an alkyl group, a cycloalkyl group, an aralkyl group, or an aryl group (each group possibly has one or more substituens); each of R3, R4, R5 and R7 is hydrogen, a halogen atom, cyano, hydroxyl, nitro, carboxyl, sulfo, an alkyl group, a cycloalkyl group, an aralkyl group, an aryl group, an alkoxy group, an alkylthio group, an acyl group, an acyloxy group, an alkoxycarbonyl group, an alkylamino group, an arylamino group, or an alkylsufonyl group; or a set of R1 and R2, R1 and the substituent of the benzene ring A, R2 and the substituent of the benzene ring A, R3 and R4, R4 and R5, or R5 and R6 can be combined to form a heterocyclic or aromatic ring

Abstract: An ink comprising water, a water-dissipatable polymer and one or more dyes of Formula (1): wherein: R1 is H or a substituent; R2 and R3 are each independently optionally substituted alkyl, aryl or aralkyl, or R2 and R3 together with the carbon atom to which they are attached form an optionally substituted ring; R4 is H or optionally substituted alkyl, aryl or aralkyl; and D is an optionally substituted arylene group. Also claimed are the dyes of Formula (1), ink jet printing processes and cartridges containing the inks.

Abstract: A color ink jet ink set for color printing comprising: (a) a yellow ink comprising a carrier and Direct Yellow 107, Direct Yellow 132 or Direct Yellow 86; (b) a magenta ink comprising a carrier and a water soluble, transition metal complex of an 8-heterocyclylazo-5-hydroxyquinoline dye; and (c) a cyan ink comprising a carrier and a sulfonated copper phthalocyanine dye.

Abstract: An ink jet ink composition comprising water, a humectant and a water-soluble azoindole dye.
