CI 1020

Description:
CI 1020, also known as Pigment Yellow 151, is an organic pigment primarily used in various applications such as coatings, plastics, and inks due to its vibrant yellow color and excellent lightfastness. It belongs to the class of azo pigments, characterized by their azo (-N=N-) functional group, which contributes to their color properties. CI 1020 exhibits good thermal stability and resistance to solvents, making it suitable for outdoor applications where exposure to UV light and harsh environmental conditions is a concern. The pigment is typically synthesized through a chemical reaction involving diazotization and coupling reactions, resulting in a stable, insoluble compound. Its non-toxic nature and compliance with various safety regulations make it a preferred choice in consumer products. However, as with many pigments, proper handling and safety measures should be observed to minimize any potential health risks during manufacturing and application processes. Overall, CI 1020 is valued for its performance characteristics and versatility in various industrial applications.
