The purple thermochromic dye coupler is an electron-donating type compound with specific optical properties. It remains colorless or light in color at room temperature. Upon heating to the reaction temperature, it can rapidly interact with the color-developing receptor, thereby displaying a purple color. This type of material exhibits excellent color consistency and thermal responsiveness in processing and printing applications.
It is a thermochromic material that can produce a purple coloration effect under specific temperature conditions. It is commonly used in heat-sensitive paper, labels, receipts, temperature-controlled indicator cards, etc. As one of the key components in the heat-sensitive coloration system, this developer is usually combined with color-forming acids and color-forming auxiliaries. By heating, it triggers the color change and forms a stable purple visual effect.
