    Abstract: The transparent coloring composition comprises a solvent and an organic-inorganic composite pigment comprising (i) fine white inorganic particles and an organic pigment adhered to the surface of the respective fine white inorganic particles, or (ii) fine white inorganic particles, a surface modifier coated on the surface of the respective fine white inorganic particles and an organic pigment adhered onto the surface modifier coating layer, primary particles of the composite pigment having an average particle diameter of 1 to 100 nm. The transparent coloring composition for color filter comprises the above transparent coloring composition and a transparent resin containing at least one acid group and/or latent acid group. The color filter is produced by applying a film-forming material made of the above transparent coloring composition for color filter on a substrate. The transparent coloring composition is suitable as a coloring composition for color filter because of excellent dispersibility and spectral properties. Further, the color filter produced from the transparent coloring composition can be suitably used as color filters for color liquid crystal displays (LCD) or the like owing to the excellent spectral properties.

    Abstract: The present invention relates to a magnetic particle-containing water dispersion wherein the magnetic particles have a primary particle diameter of 5 to 15 nm and an average secondary particle diameter of 10 to 60 nm, and the water dispersion has a zeta potential of not more than −20 mV when a pH value of the water dispersion lies within the range of 6 to 8, and further a surface of the respective magnetic particles is coated with a carboxyl group-containing polymer. The magnetic particle-containing water dispersion is produced by heating an aqueous solution in which the carboxyl group-containing polymer is dissolved, to a temperature of 90 to 100° C. in a nitrogen atmosphere; adding a solution of a ferrous (II) salt and a ferric (III) salt and an alkali solution to the aqueous solution to react with each other at the same temperature; adding ethanol to the solution to obtain a precipitate; and removing a supernatant liquid from the solution, and then dispersing the precipitate in water and subjecting the resulting dispersion to dialysis. The magnetic particle-containing water dispersion is useful as a magnetic particle-containing water dispersion capable of producing magnetic particle-containing drugs for diagnosis and therapies which can exhibit a uniform functionality, with a good reproducibility.
