Contributions by scientists working in international laboratories provide the novice researcher with synthetic data and high-technology applications of leuco dyes. 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.
