Novel Nanopigments with a Thiazole Moiety for Printing Paper, Carton, and Polyester Fabrics: Synthesis, Characterization, and Color Strength with Comparative Study

Abstract A series of new coloring materials in nanoscale based on 5-(2-aminothiazol-5-yl) thiazol-2-amine and 5-(4-aminophenyl) were synthesized. The pigments prepared using a grinding high˗energy ball-milling technique. X-ray diffraction transmission electron microscopy employed to determine the particle size (40–80 nm). synthesized normal applied printing polyester fabrics. fastness colorimetric properties printed samples carefully studied. Additionally, as water-based flexographic ink for paper carton. hue color L * , b glossiness, light measured. comparison heterocyclic benzidine analogs with commercial demonstrated better results, particularly pigments.
