ABSTRACT:
Tetrafluoroethoxybenzenes, and their acid addition salts, of the general formula: ##STR1## in which R.sup.1 may represent hydrogen or an alkyl having from 1 to 4 carbon atoms and R.sup.2, R.sup.3 and R.sup.4 represent one or more of the same or different substituents selected from hydrogen, an alkyl having 1 to 4 carbon atoms or mono- or dihydroxyalkyls having 1 to 4 carbon atoms, provided that the amino groups are situated relative to one another in an ortho- or meta- position and R.sup.1, R.sup.2, R.sup.3 and R.sup.4 do not simultaneously represent hydrogen when the amino groups are arranged in a 2,4-position. The compounds of the invention, along with 2,4-diaminotetrafluoroethoxybenzene, are useful as coupler components in oxidative hair coloring agents. A process for making the compounds, as well as a separate process for making the mono-N-.beta.-hydroxyethyl compounds, is provided.
