ABSTRACT

Anil compounds are Schiff bases derived from aniline moiety containing phenyl or substituted phenyl group, which sometimes called Azo dyes. These Schiff bases can be directly prepared from aromatic amine with aromatic carbonyl groups, which are stable and can be manipulated under different and suitable conditions. The phenomena of coordination of Schiff bases with metal ions give the Schiff bases the good advantages to be introduced in the dyes synthesis. The classification of dyes is based on the chemical structure or on the basis of the chromophoric system. The metal complex dyes are combinations of dyestuff and metal ions, in which the coordination complex can be applied or used to be improvement factors in dye techniques. The investigation and the characterization of the resulted dyes were performed by using different physical techniques. The produced dyes were applied to different fibres, such as sheep wool and goat hair with two Schiff bases synthesised from salicylaldehyde either with 2-aminophenol or 2-aminobenzyl alcohol. Also the investigation includes the effect of mordant type on the dyeing process.
