This chemical is widely used in the development of pressure-sensitive and thermosensitive recording materials. It is a key component in the production of carbonless copy paper, where it acts as a color-forming agent that reacts with acidic developers to produce visible marks. Additionally, it is utilized in thermal paper applications, such as receipts and labels, where heat activates the color change. Its stability and efficiency in color development make it a preferred choice in industries requiring reliable and high-quality printing solutions.
