Abstract
The invention comprises dyes of the formula <FORM:1112873/C4-C5/1> where R is a substituent other than sulphonic acid or carboxylic acid; R1 is hydrogen or alkyl of 1-12 carbon atoms; R2 and R3 are alkyl of 1-12 carbon atoms, cycloalkyl, aralkyl or aryl; R4 and R5 are hydrogen, alkyl of 1-12 carbon atoms, cycloalkyl, aralkyl or aryl; X is chlorine or bromine; n is 1-5 and m is 0-4, at least one m being less than 4. The compounds are prepared by heating together in solution at 50-100 DEG C. compounds of the formulae <FORM:1112873/C4-C5/2> <FORM:1112873/C4-C5/3> The intermediate halomethyl compounds may be prepared by reacting the parent azobenzene in concentrated sulphuric acid with a bis-halomethyl ether or with paraformaldehyde and a halosulphonic acid.
