Organic pigments have higher coloring strength, brighter colors and complete chromatography. In recent years, we have been developing new heterocyclic yellow, orange, red and purple spectrum pigment varieties, and have the application performance matching with phthalocyanine blue and green pigments. It is not only used for printing ink and plastic coloring, but also widely used for metal surface coating and architectural coating coloring. The organic pigments commonly used in coatings include classical pigments and high-grade pigments to meet the requirements of light resistance and solvent resistance. The main application areas of coatings are distinguished, including automotive paints, architectural and decorative paints, industrial paints, powder coatings, coil steel coatings, etc.                   In the early days, the pigments used for coloring low-grade paints mostly belong to insoluble azo pigments, with simple process, low cost and good application performance, for example, Hansa system yellow (C.I. pigment yellow 1, pigment yellow 3 and pigment yellow 5, etc.), orange spectrum (C.I. pigment orange 5), red spectrum: toluidine red (C.I. pigment red 3), toluidine violet red (C.I. pigment red 13); blue and green spectrum are For phthalocyanine blue and phthalocyanine green and other varieties. Yuhong brand pigment yellow spectrum. C.I. Pigment Yellow 74 (General purpose, recommended for construction and decorative paints.) C.I. Pigment Yellow 83 (High coloring power, recommended to be used in industrial paints, also can be used in construction and decorative paints, wax for powder coatings.) C.I. Pigment Yellow 139 (red light yellow, recommended for automotive coatings, industrial coatings, powder coatings, coil steel coatings.) C.I. Pigment Yellow 151 (Greenish yellow, recommended for automotive coatings, also can be used in architectural and decorative paints.) C.I. Pigment Yellow 154 (neutral yellow, good weather resistance, recommended for automotive coatings, architectural and decorative paints, industrial coatings, also can be used in powder coatings, coil steel coatings.) Yuhong brand pigment orange spectrum. C.I. Pigment Orange 13 (yellow light orange, recommended for industrial coatings, powder coatings) Yuhong brand pigment red spectrum. C.I. Pigment Red 122 (excellent light, heat and solvent resistance, excellent migration resistance, can be used in automotive coatings, architectural and decorative paints, industrial coatings, powder coatings, etc.) C.I.
