COORDINATING ACID AZO DYES AND DIRECT DYES DERIVED FROM 8-HYDROXYQUINOLINE

The paper describes the synthesis of some complexable acid azo dyes and of some direct dyes derived from 8-hydroxyquinoline.The structure of the resulted dyes has been checked with the help of elemental analysis, of vibration IR spectra in KBr pallete and of electronic spectra in aqueous solution.The acid dyes have been applied on wool and the direct dyes on cotton.The obtained dyeings have been treated with chromium and copper salts, respectively, in order to obtain the complexes of the dyestuff on the fiber and to improve in this way their fastness to wet treatments and to light.After coppered and after chromed dyeings, they possess excellent tinctorial qualities.
