| 20100020274 | COLORANT, COLOR FILTER, LCD DEVICE, COMPOSITION AND METHOD FOR PREPARING THE SAME - The present invention relates to a colorant, a color filter, LCD device, a composition and a method for preparing the same. The colorant covers pigment particles by using the acrylic acid polymer having an acid value greater than 20 mgKOH/g and containing aromatic group so as to greatly improve the stability while improving the dispersion ability of the pigment particles. By the above colorant, the photosensitive resin composition ensures that the developing performance is basically not influenced so that the photosensitive resin composition can meet the need of high transmissivity, high color purity, and high contrast for a color filter. A pattern on the color filter is formed by using the photosensitive resin composition having high dispersion stability and developing performance so as to greatly improve transmissivity, color purity, and contrast. An LCD device uses the color filter with high transmissivity, high color purity, and high contrast so as to greatly improve the display effect of color images. | 01-28-2010 |
