    Abstract: PROBLEM TO BE SOLVED: To obtain a dispersion solution which does not give a stain after sprayed on the substrate as well as good in storage stability by compounding carbon black, a cationic surfactant and a nonionic surfactant with water at a specific ratio. SOLUTION: 1 to 45 mass % of carbon black, 1 to 40 mass % of a cationic surfactant and 0.5 to 10 mass % of a nonionic surfactant are compounded. For the carbon black, a pigment, a pigment carbon black having an average particle size of 8 to 80 nm as the primary particles and the DBP value of 40 to 200 mg/100 g, which is prepared using a furnace method, gas black method, channel method or lamp black method, can be used. The carbon black is dispersed in water together with a wetting agent, which may be dispersed by use of a purl mill, an ultrasonic apparatus or Ultra-Turrax according to circumstances. Alternatively, it is further centrifuged or filtered. The pH of the dispersion solution is preferably 1 to 4.

    Abstract: PROBLEM TO BE SOLVED: To obtain high optical density and excellent abrasion resistance by blending a carbon black, a surfactant and water in a specific ratio. SOLUTION: This carbon black dispersion contains water, 1-40 wt.% carbon black and 1-30 wt.% surfactant. A pigment carbon black with an average primary particle diameter of 8-80 nm and a DBP value of 40-200 ml/100 g can be used as the carbon black. Preferably, a gas carbon black with an average primary particle diameter of 8-30 nm is used. A combination of two nonionic surfactants is used as the surfactant. The combination comprises (A) a crosslinked polyoxyethylene acrylic acid and (B) an alkyloxy ethylene wherein the ratio of B to A is preferably 1:2-1:10. In addition to the nonionic surfactants, anionic surfactants can be additionally used, which can prevent an increase in viscosity of the dispersion during storage.
