Gold has always fascinated people because of its unique appearance.1 The yellowish metal shows high hiding power and shine even in very thin layers. In addition, it has an extreme light-dark flop. By mixing copper and silver, different color impressions can be achieved. These color shades can now be imitated in coatings, printing inks and plastics with new ultra-thin pigment (UTP)-based effect pigments.2 For this purpose, Schlenk has transferred the ternary system known from metallurgy, consisting of gold, silver and copper (Au-Ag-Cu), to the effect pigment domain with the development of the Zenexo® Ternary System (ZTS) (YY-YS-OO).3 With the individual effect pigments GoldenShine (YY), GoldenWhite (YS) or CopperGlow (OO), it is possible to implement color shades in liquid and powder coatings, printing inks, or masterbatch and plastics previously known only from (semi-) precious metals (Figure 1). The new effect pigments have exceptional properties and their application profile allows new accents to be set in terms of color saturation, hiding power and color gamut in the mentioned applications.3
