Process of claim 1 wherein 1-aminonaphthalene-4,7-disulphonic acid is prepared from 1-chloronaphthalene-4,7-disulphonic acid at temperatures below 220° C, and then the temperature of the reaction mixture is raised to 220° to 350° C in the presence of ammonia and water so as to obtain 1-aminonaphthalene-7-sulphonic acid.
