    摘要: High-quality coloring carbon black having a specific surface area (S.sub.BET), an area average diameter (D.sub.a) and a pore volume (AV.sub.Hg) which make both the roughness factor (RF) and aggregate factor (AF) as calculated by the following equations, negative values:RF=S.sub.BET -28710/(D.sub.a)+1450AF=AV.sub.Hg +14.times.(D.sub.a)-290where S.sub.BET is the specific surface area (m.sup.2 /g) of the carbon black as measured by a BET nitrogen absorption method, D.sub.a is the area average diameter (m.mu.m) of the carbon black as measured by an electron microscopic measuring method, and AV.sub.Hg is the pore volume (cc/100 g) of the carbon black as measured by a mercury porosimeter, provided D.sub.a is at most 17 m.mu.m.
