Tetrafluoroethoxybenzenes, and their acid addition salts, of the general formula: STR1 in which R1 may represent hydrogen or an alkyl having from 1 to 4 carbon atoms and R2, R3 and R4 represent one or more of the same or different substituents selected from hydrogen, an alkyl having 1 to 4 carbon atoms or mono- or dihydroxylalkyls having 1 to 4 carbon atoms, provided that the amino groups are situated relative to one another in an ortho- or meta- position and R1, R2, R3 and R4 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-β-hydroxylethyl compounds, is provided.
