A pixel-forming colorant composition contains at least one green colorant selected from the group consisting of the following pigments (A) and (B) and pigment derivative (C): The pixel-forming colorant composition is useful for the formation of G pixels of three primary-color pixels on color filters.

Pixel-forming colorant compositions and their use

An aqueous pigment dispersion is produced by ultrafinely dispersing a pigment dispersion mixture, which has been obtained by mixing at least a pigment and a dispersant in an aqueous medium, with microbeads having diameters of not smaller than 0.02 mm but smaller than 0.2 mm. A color composition for a color filter is produced by dispersing a mixture of a pigment, a dispersant, a resin varnish and a solvent with the microbeads in a mill.

Water-based pigment dispersions, inkjet recording inks, and color filters

A dispersant for an organic pigment contains a compound represented by the following formula (1): wherein Rand Rmay be the same or different and each independently represents a hydrogen atom, a halogen atom, a hydroxyl group, a primary, secondary or tertiary amino group, an alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted phthalimidomethyl group, Rand Rmay be the same or different and each independently represents a hydrogen atom or a lower alkyl group, and n means an average number of introduced sulfonic groups and stands for a number of from 0.5 to 3; or at least one salt selected from the group consisting of its metal salt, ammonium salt, organic amine salt, and organic quaternary ammonium salt. Also disclosed are a readily-dispersing pigment composition, a pigment dispersion, a colored coating fluid for color filters, a fabrication process of a color filter and a color filter, all of which make use of the dispersant.

Dispersants for organic pigments

The present invention is provided for considerably shortening the construction time of a building that is applied to nuclear power plants. When constructing the building, megablocks having a height that extends to a plurality of floors are produced, and together with combining those megablocks, concrete is poured inside them to form a wall member composed of a megawall structure of steel plate reinforced concrete construction. Alternatively, in addition to the wall megablocks, floor megablocks for forming the floor member of the building are used, and together with combining those megablocks, concrete is poured inside or above them to form a structural member (wall member and floor member) composed of a megawall structure of steel plate reinforced concrete construction.
