Properties
The color palette is soft, with a series transitioning from orange-red to purple-red tones. Tri-ring pigments possess exceptional pigment characteristics and chemical properties, featuring high tinting strength and covering power, excellent light and weather fastness, and resistance to high temperatures. They are insoluble in alkalis and stable within a certain pH range, while fully soluble in concentrated hydrochloric acid. These pigments are insoluble in water and organic solvents and exhibit excellent rust prevention and UV resistance.
