SYNTHESIS, COLORFASTNESS EVALUATION AND UTILIZATION OF HUMIC ACID DERIVED DYES / PIGMENT

Pakistan coal derived humic acid (HAL) salt was used to synthesize direct azo and acid dyes by coupling reaction with arylamines and its substituted derivatives (R1-R15) for dyeing industry as a reaction intermediates. A variety of color shades ranging from light to deep brown and yellowish were obt...
