Processes for coloring a fiber or textile by adding a carbon black product having an organic group attached to the carbon black. In one process at least one diazonium salt reacts with a carbon black in the absence of an externally applied electric current sufficient 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 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.

omega-(4-aminophenylsulfonamido)alkyldisulfides and omega-(4-aminophenylsulfonamido)alkanethiosulfates was synthesized from the reaction of p-acetamidobenzenesulfanilyl chloride and either the aminoalkyl disulfide dihydrobromide or the aminoalkyl bromide hydrobromide followed by sodium thiosulfate. Several of the compounds showed inhibitory activityagainstdihydropteroatesynthetase isolated from a
