Problems solved by technology

In this case, when the polymerizable monomer is cured in the process of manufacturing the color filter, aggregation of the dye or phase separation may occur due to the combination of the dye and the polymerizable monomer, resulting in deterioration of the color tone or a marked drop in contrast

Abstract

An object of the invention is to provide an ink set for ink-jet capable of manufacturing color filter with excellent medicament resistance, color reproducibility and the like characters, color filter obtained by the ink set for ink-jet, color filter obtained by the ink set for ink-jet, a method for producing color filter and image display device. The inventive ink set for ink-jet contains printing ink for ink-jet, wherein the printing ink for ink-jet contains an organic solvent soluble dyes, polymerism monomer and organic solvents, and the contained polymerism monomer displays the prescribed capryl alcohol / water distribution coefficient ClogP.

Description

technical field [0001] The present invention relates to an ink cartridge, a color filter and a manufacturing method thereof, and a liquid crystal display and an image display device using them. Background technique [0002] In recent years, with the development of personal computers, especially large-screen liquid crystal televisions, the demand for liquid crystal displays (LCDs), especially color liquid crystal displays, tends to increase. On the other hand, since color liquid crystal displays are expensive, demands for cost reduction are increasing. In particular, there is a high demand for cost reduction of color filters which account for a large proportion of cost. Such a color filter generally has a coloring pattern of three primary colors of red (R), green (G) and blue (B). In a liquid crystal display equipped with this color filter, by turning on and off the electrodes corresponding to the R, G, and B pixels, the liquid crystal acts as a switch, and light passes thr...
