This chemical is widely used as a key component in the production of pressure-sensitive and thermal papers. It functions as a color-forming agent, which reacts with acidic developers to produce visible marks when subjected to heat or pressure. This makes it essential for applications such as printing receipts, labels, and tickets. Additionally, it is employed in the manufacturing of carbonless copy papers, where it helps in creating duplicate records without the need for carbon paper. Its ability to generate clear and durable prints under specific conditions makes it a valuable material in industries requiring efficient and reliable documentation solutions.
