CARBON BLACK LOADED COMPOSITION, COLORANT COMPOSITION AND CONDUCTIVE COMPOSITION

摘要

A composition, colorant composition or conductive composition loaded with a novel carbon black whose number average particle diameter, in terms of Feret's diameter, falls within a given range. There is provided a composition characterized by containing carbon black of 5 to 300 nm number average particle diameter, in terms of Feret's diameter, wherein the content of primary particles is = 5% on a numerical basis. This composition is uniform in coloring and conductive properties, so that the coloring and conductive properties of a final form utilizing this composition can be uniformed.
