Thermochromic Leuco Dye. We mix numerous Leuco Dyes with colour developers and a series of fatty acids, esters and alcohols that each have defined melt points to provide a range of materials that respond to different temperatures producing a variety of colours. These products all change leuco dye Molecular formula : CAS : nature : coupler anion and quinone Diimine (QDI) coupling reaction occurred, the first generation of dye precursors are colorless, known as the color-dye hidden. Hidden-color moment in the developer was QDI oxidized dye. Leuco Dye products are available in a wide variety of colors, temperatures and forms, which include powder, slurry, water and solvent based ink, epoxy, and master batch.

A leuco dye (from the Greek λευκός leukos: white ) is a dye which can switch between two chemical forms; one of which is colorless. Reversible transformations can be caused by heat, light or pH; resulting in examples of thermochromism, photochromism and halochromism respectively. Irreversible transformations typically involve reduction or oxidation. Covering leuco dye classes that exhibit reasonable stability, the book discusses photochromic materials that have wide-ranging applications in memory technology, leuco dyes for color photography, and a special class of dyes formulated by reduction instead of the oxidation process. Contributions by scientists working in international laboratories provide the novice researcher with synthetic data and high-technology applications of leuco dyes.

Leuco dye inks, though, feature more durable chemistry that lets product designers employ these inks for all sorts of fun applications. One of the most famous applications of leuco dyes is on cans of Coors Light beer. These cans feature a graphic of a mountain landscape next to the company's logo. At room temperature, the mountains appear white.
leuco Malachite Green (LMG) can dissolve. During irradiation, the LMG dye precursor converts to Malachite Green (MG+). The most sensitive reported LMG gel formulation contains 0.3 mM LMG leuco dye, 16 mM trichloroacetic acid, 7 mM Triton X-100 and 4% w/w gelatin.

For example, the spiro form of an oxazine is a colorless leuco dye; the conjugated system of the oxazine and another aromatic part of the molecule is separated by an sp3-hybridized "spiro" carbon.After protonating a part of the molecule, irradiation with UV light (see Photochromism), or introducing other
