Abstract:
PROBLEM TO BE SOLVED: To provide a reaction method for oxidizing carbon black, having less precipitate, capable of obtaining dispersion in a high yield, which is also good in the point of a long period preservation stability, self-dispersing type carbon black oxidized by the reaction method and aqueous pigment-based jet ink excellent especially in both of dispersion stability and ejection stability of the ink by obtaining the ink composition consisting mainly of the self-dispersion type carbon black dispersion. SOLUTION: This method for producing surface-treated carbon black is characterized by crushing (a) carbon black in water by using (c) a dispersing agent in advance, and then liquid phase-oxidizing by using (b) a hypochlorite solution. The method for producing self-dispersing type carbon black dispersion is provided by removing ≥50% reaction supernatant from the slurry containing the oxidative surface-treated carbon black by a centrifugal separation method and/or decantation method, diluting the rest of slurry containing the carbon black with deionized water and performing deionization by an ultrafiltration method.

Abstract:
PROBLEM TO BE SOLVED: To provide a titanium dioxide dispersing element for a dye sensitized solar battery which can be manufactured by a simple and low cost method, a titanium dioxide thin film formed by using the dispersing element and the dye sensitized solar battery manufactured by using the thin film. SOLUTION: The titanium dioxide dispersing element for the dye sensitized solar battery is composed containing a cellulose system or a butyral system additive with terpineol, alcohols, glycol ethers, or glycol ether acetates as an independent or mixed solvent. In this case, an organic titanium compound or a niobium compound is added to these dispersing elements. Furthermore, the titanium dioxide and polyvinyl butyral resin are made into solid chips with two rolls and the chips are dissolved and produced. In addition, the titanium dioxide thin film formed by using the titanium dioxide dispersing element, and the dye sensitive solar battery manufactured by using the film is manufactured.

Abstract:
PROBLEM TO BE SOLVED: To provide an oil-based uniform dispersion composition of a pigment having sufficient dispersion stability and service environmental durability as an ink, etc., for preparing various kinds of recordings or displays or display-related elements as an oil-based dispersion composition of the pigment by uniformly dispersing various kinds of pigments in an oil-based medium, especially a silicone oil with a specific dispersing agent and to establish a method for producing the composition. SOLUTION: The oil-based uniform dispersion composition of the pigment is characterized as follows. A dispersion medium which is an essential component is a silicone oil consisting essentially of dimethylpolysiloxane and a dispersoid which is the essential component is an inorganic or an organic pigment. A dispersing agent which is the essential component is selected from a polyoxyethylene-methylpolysiloxane copolymer and a polyvinylbutyral in selecting the essential components of the oil-based uniform dispersion composition of the pigment.
