titleOfInvention | Method of producing an aqueous dispersion of surface-treated carbon black |
abstract | The purpose of the object is to provide an aqueous dispersion of a carbon black which is suitable as an aqueous black ink for inkjet printers. An aqueous dispersion of a surface-treated carbon black comprising the surface-treated carbon black, which has been chemically modified by dehydrating and condensing a hydrophilic surface functional group of carbon black with an amino group-containing compound by using a triazine-based condensing agent to thereby form an amide bond, dispersed in an aqueous medium; and a method of producing an aqueous dispersion of a surface-treated carbon black which comprises adding an amino group-containing compound and a triazine-based condensing agent to a dispersion wherein a carbon black, which has been oxidized to form a hydrophilic surface functional group, is dispersed in an aqueous medium, stirring the mixture at room temperature to thereby dehydrate and condense the above-described hydrophilic surface functional group with the amino group-containing compound, and then removing large particles, the unreacted amino group-containing compound, a decomposition product of the triazine-based condensing agent and the unreacted matter followed by neutralization, purification and concentration. |
