In many cases it is difficult to decide whither an ortho-oxyazo compound contains a hydroxyl group, or whetherits constitution is that of a hydrazone. Monohydroxylatedcolouring matters containing the hydroxyl group in theortho position to certain atomic groups arc capable of dyeingmordanted fibre. By substituting in such colouring matters the cpiiuone oxygen atom for the hydroxyl group the resultingcompounds lose their affin
