Pigment yellow 12 CAS 15541-56-7 introduce
In practice, Pigment yellow 12 is fascinating. In the field of printing inks, it is a powerful assistant for printing eye-catching yellow promotional materials and exquisite reading materials, whether it is offset printing ink for advertising posters and magazine illustrations, or flexographic printing ink for food packaging and pharmaceutical label printing, it can show a rich, pure and long-lasting yellow. This yellow color is super lightfast, even when exposed to strong light for a long time, the color is still bright and eye-catching; It also has excellent migration resistance, and is not prone to bleeding and discoloration when in contact with different substances and temperature changes, ensuring that the printed matter will remain as good as new for a long time. In the paint industry, it is integrated into building exterior wall coatings, industrial protective coatings, etc., as a key ingredient, to coat facilities with a bright and eye-catching yellow “coat”, such as the exterior walls of large shopping malls, factory warehouses, which not only play a protective role, but also enhance recognition with its bright yellow color to ensure a beautiful appearance.
