Abstract
To provide a carbonaceous filler having excellent dispersibility in polyols without damaging characteristics of the carbonaceous filler.SOLUTION: A carbon black-supported carbonaceous filler formed by supporting carbon black on a carbonaceous material, wherein the carbonaceous material is a component content of 80% or more of fixed carbon, less than 8% of volatile content, and less than 4% of ash content (anhydrous base weight) in industrial analysis, and the phenolic hydroxy group per external specific surface area is 0.005 mmol / m2 or more, an average particle size (D50) is 0.1-100 μm of the carbonaceous particles, the carbon black is supported in the range of 1 pt. mass or more and 200 pts. mass or less relative to 100 pts. mass of the carbonaceous material.SELECTED DRAWING: None
