'''Direct Blue 1''' is an [organic compound](/source/organic_compound) that is one of many [azo dye](/source/azo_dye)s.  This salt is used as a [substantive dye](/source/substantive_dye) for textiles with high contents of cellulose, i.e. cotton.  It is prepared by the azo coupling of the aminonaphthalene and diazotized derivative of [''o''-dianisidine](/source/O-Dianisidine).<ref name=Azodye>Klaus Hunger, Peter Mischke, Wolfgang Rieper, Roderich Raue, Klaus Kunde, Aloys Engel: "Azo Dyes" in ''Ullmann's Encyclopedia of Industrial Chemistry'', 2005, Wiley-VCH, Weinheim.{{doi|10.1002/14356007.a03_245}}.</ref>
