| Abstract | ||||
| This article was designed to synthesize new pigments derived from Lithol Rubine (LR) important in inks industry and to investigate their physical properties. Several pigments, used as special inks for printing and essential in inks industry, were successfully prepared via the reaction of Lithol Rubine (LR) with salts of Cu (II) and Zn (II) ions in ethanolic solutions. The obtained pigments were isolated as solid compounds and characterized through elemental analysis, UV-Vis, FT- IR, 1HNMR spectra, specific gravity, melting point, molar conductivity and magnetic moments measurements. Their physical properties related to dyeing were investigated using "American Standard Testing Methods (ASTM)" and the pigments were then applied to ink formulations. The results of this study showed that the output of newly prepared pigments is comparable to currently used commercial pigments. Lithol Rubine currently used, and the new pigments can be vital in other different industries such as coated papers, crayons, rubber, Paints, ink, and baking enamels. The prepared pigments would be a cost-effective and good substitute for the original commercially available and costly pigments used in the inks industry. | ||||
