| description | PROBLEM TO BE SOLVED: To provide an aqueous carbon black dispersion excellent in thermal storage stability.SOLUTION: This carbon black dispersion includes at least carbon black, a polymer and an aqueous medium, has viscosity of 4.0 cP or lower, and keeps its pH decremental range within 1.0 when stored at 70°C for one week in a hermetically sealed state. Such the carbon black dispersion possesses better thermal storage stability compared with conventional ones. Preferably, the polymer has an acid value of ≤240 mg-KOH/g, a weight-average molecular weight of ≥15,000 and the content of components having ≤4,000 weight-average molecular weight is ≤20 wt.%. |
