Ink, color filter, liquid crystal panel, and computer, and process for producing color filter

摘要

Provided is a novel ink which is suitable for producing a color filter by an ink-jet system. The ink comprises a pyrazolone dye of the general formula (I): <CHEM> wherein R1 and R2 are each independently a hydrogen atom, an OH group, a halogen atom, a linear or branched alkyl group having 1 to 5 carbon atoms, a nitro group, a CF3 group or an SO3(M1) group, where M1 is an alkali metal or NH4; both R3 and R4 are an SO3(M2) group, where M2 is an alkali metal or NH4. <IMAGE>
