Carbon black for ink and ink |
| abstract |
The problem to be solved by the present invention is to provide carbon black, ink, etc., which are excellent in dispersion stability. The carbon black of the present invention contains 0.01 to 2.00 parts by mass of iron element per 100 parts by mass of carbon black. The ratio (Fe/C) of the carbon black particle surface iron element concentration Fe (atomic%) and the carbon black particle surface carbon element concentration C (atomic%) measured by X-ray photoelectron spectroscopy is 0.001 to 0.010. is preferred. |
