The purpose of this study is to prepare new pigments derived from Red Lake C (RLC) to be applied in the inks industry and to identify their chemical nature, as well as their physical properties.
A number of pigments that could be applied in special printing were prepared via the reactions of RLC with appropriate Ni(II) and Zn(II) salts in aqueous and ethanolic solutions. The obtained pigments were prepared as solid compounds and characterized using different instrumental analysis such as Ultraviolet-Visible, Fourier Transform Infrared Spectroscopy, 1H NMR spectra and magnetic measurements. The physical properties of these pigments were investigated using “American Standard Testing Methods” (ASTM). After that, the pigments were applied in ink formulations to test their performance and open the way to their real applications in the printing inks industry.
The results of this work revealed that the performance of the new prepared pigments is closer to the performance of the commercial pigments which are already used in ink industry.
Red lake C, as well as the new pigments, can be applied in other different industries such as coated papers, crayons, rubber and baking enamels.
The prepared pigments will be economically feasible and a good alternative to the original expensive commercial pigments which are already used in the inks industry.
