  • Patent number: 6826001
    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.

  • Patent number: 6787295
    Abstract: There is disclosed a method of preparing a photographic solid fine-grain dispersion, the method comprising the steps of: successively bringing a slurry of a water-insoluble photographically useful compound in a grinding chamber of a dispersing machine, which chamber is filled with media, allowing the compound to contact the media in the grinding chamber, to produce fine grains of the compound successively, successively separating the media from the compound by centrifugal force, and taking the compound out of the grinding chamber, using specific media with given physical properties. There is also disclosed a dispersion obtained by the method. According to the method, the photographic solid fine-grain dispersion is prepared efficiently, without coarse grains or abrasion materials resulting from media or so, and the dispersion causes no defect when coated in a form of a coating film.
