"PROCESS FOR PREPARING SMOKE BLACK PRODUCT, SMOKE BLACK PRODUCT, PROCESS FOR SMOKE BLACK PRODUCT, RUBBER COMPOSITION, AND TEXTILE OR FIBER COMPOSITION". Processes for preparing a carbon black product having an organic group attached to carbon black. In one process at least one diazonium salt reacts with a carbon black in the absence of sufficient externally applied electric current to reduce the diazonium salt. In another process at least one diazonium salt reacts with a carbon black in a protic reaction medium. Carbon black products which may be prepared according to the process of the invention are described as well as uses of such carbon black products in plastic compositions, rubber compositions, paper compositions and textile compositions.
