Abstract: An object to be achieved by the present invention is to provide a pigment which is comfortable and smooth to the touch in a coating, spreads well on the skin, for example, when used in a cosmetic material such as a foundation or an eye shadow, and exhibits good color development and gloss. A pigment of the present invention is a coated pigment formed by coating a surface of a flaky base material made of at least one metal or metal oxide with a colorant. The surface of the flaky base material has a coarse particle area fraction of 9% or less. Further, it is preferable that the flaky base material be at least one or more selected from the group consisting of mica, aluminum, alumina, and glass.

Abstract: A green pigment for a color filter including a phthalocyanine green pigment and capable of expressing a region of xy-chromaticity coordinate enclosed by predetermined equations 1, 2 and 3 defined by the XYZ color system of the CIE when the green pigment is solely subjected to colorimetry. Moreover, using the above-mentioned green pigment, it provides a photosensitive color composition capable of forming a color filter having a wide color reproduction range and a high transmittance. Furthermore, it provides a color filter having a wide color reproduction range and a high transmittance with a green pixel formed using the above mentioned photosensitive color composition, and a liquid crystal panel using the color filter.

Abstract: The present invention relates to a pigment composition or pigment dispersion that is ideal for producing the blue pixel portion of a color filter for a liquid crystal display device, and a color filter. The invention has an object of providing a color filter having a blue pixel portion that yields a liquid crystal display device having a high degree of contrast that enables the display screen to be viewed with improved clarity, and a high level of brightness that produces a brighter display screen, as well as providing a pigment composition or dispersion that can be used to produce the color filter. The above object can be realized by using a dioxazine derivative that is substituted with a sulfamoyl group having a specific polyalkylene oxide group, and a pigment composition or dispersion for a color filter that includes this dioxazine derivative and a blue organic pigment or violet organic pigment.

Abstract: An object of the present invention is to provide a green pigment for a color filter, capable of displaying the chromaticity coordinates not to be displayed by the conventional green pigments, having the excellent color strength as a green color which is not excessively strong in a blue tinge, and a high transmittance, and moreover, to provide a photosensitive color composition, a pigment dispersion, a color filter and a liquid crystal panel, using the above-mentioned green pigment. In order to achieve the above-mentioned object, the present invention provides a green pigment for a color filter comprised of a phthalocyanine green pigment and capable of expressing a region of xy-chromaticity coordinate enclosed by predetermined equations 1, 2 and 3 defined by the XYZ color system of the CIE when the green pigment is solely subjected to colorimetry.

Abstract: The present invention provides a color filter which is more durable than a dye-type color filter and also has green pixel portions which exhibit a bright green color having a strong yellowish tinge when used in a liquid crystal display device using a three-band lamp having a main emission line of green light of about 545 nm as a light source, thus enabling the liquid crystal display device to display bright images even when using a backlighting light source having a low intensity. This color filter comprises green pixel portions which (1) contain a halogenated metal phthalocyanine dye wherein 8 to 16 halogen atoms are bonded to benzene rings in one phthalocyanine molecule, and (2) exhibit maximum transmittance at a wavelength within a range from 520 nm to 590 nm with respect to the transmission spectra of the entire range of visible light.
