摘要： Provided is a novel ink which is suitable for producing a color filter by use of an ink-jet system. The ink comprises a pyrazolone dye of the general formula (I): 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.

摘要： A color filter manufacturing method comprises the steps of forming, on a substrate, a photosensitive layer that increases or develops hydrophilic property upon irradiation of light; exposing the photosensitive layer to light for patterning to form hydrophilic areas in which hydrophilic property is relatively high and non-hydrophilic areas in which hydrophilic property is lower than the hydrophilic areas; and applying a setting ink to the hydrophilic areas with an ink jet technique, thereby forming colored portions. A color filter includes at least a photosensitive layer formed on a substrate and having hydrophilic areas in which hydrophilic property is increased or developed upon irradiation of light, and colored portions formed on the hydrophilic areas of the photosensitive layer. A liquid crystal device is constructed by using the color filter. The color filter can be manufactured inexpensively with the reduced number of steps while satisfying requisite characteristics. Color mixing, color unevenness and uncolored dots are prevented and a highly reliable color filter is provided.
