Patent ID: 7485280

Claim:
Carbon black, which has: (a) a 24M4DBP absorption of at least 131 cm 3 /100 g; (b) a (1,500° C.×30 min) dehydrogenation amount of at most 1.2 mg/g; (c) a crystallite size Lc of from 10 to 17 Å; (d) a nitrogen adsorption specific surface area of from 150 to 300 m 2 /g; (e) a ratio of the Stokes mode diameter, D mod , in nm, to the 24M4DBP absorption, in cm 3 /100 g, of from 0.6 to 0.9 nm·100 g/cm 3 ; and (f) an average particle diameter as measured by a transmission electron microscope of from 14 to 24 nm.
