    摘要: An oxidized carbon black (gas black) is prepared within the MCC (medium color channel black) area showing primary particle sizes of an average diameter of 16 to 18 nm and a content of volatiles of at least 15% which, as secondary characteristics, has a specific surface area (BET) of 300 to 420 m.sup.2 /g, an oil absorption (stiff paste) conducted on carbon black powder of 430 to 560 g/100 g, an oil absorption (stiff paste) conducted on carbon black beads of 370 to 450 g/100 g, a pH value of 2 to 5, a nigrometer index of 68 to 72 and a maximum content of volatiles of 25%. The carbon black is used as a pigment in high jet black lacquers.
