Abstract

Improvements introduced in the object of the main patent no. 371,591, by "procedure for the production of insoluble and harmless coloring pigments", consisting essentially of carrying out the reductive treatment of the solution obtained by dispersing the dye in aqueous alkaline medium, in an atmosphere containing an inert gas, in order to avoid premature oxidation of the solution.
