Abstract:
PROBLEM TO BE SOLVED: To provide a carbon material which has an organic group and scarcely contains colored by-products. SOLUTION: The carbon material having an organic group is obtained by reacting a carbon material with an organic compound represented by general formula (1) (wherein X is O, S, NR 7 , or PR 7 ) and can be activated by the oxidation reaction with an oxidizing agent such as ammonium peroxodislufate, hydrogen peroxide, ozone, or oxygen.

Abstract:
PROBLEM TO BE SOLVED: To provide carbon black having an organic group which is suited in use as a filler, a reinforcing filler, a UV stabilizer, an electroconductive carbon black or a pigment, and its manufacturing method and use. SOLUTION: The carbon black has an organic group having at least one substituted -C-C- single bond or double bond through which two carbon atoms of the -C-C- single bond or double bond are bound with carbon black, and at least one carbon atom of the -C-C- single bond or double bond having at least one activated substituent. The carbon black having an organic group is manufactured by reacting an organic compound having a -C-C- double bond or triple bond which is activated by at least one substituent with carbon black.
