Relation between colour- and phase changes of a leuco dye-based thermochromic composite. [PDF]
AbstractReversible colour change of leuco dye-based composites is in general closely related to their phase change, thus the two phenomena should occur at around the same temperature and should be influenced similarly. However, spatial confinement of the analysed sample affects the change in colour differently compared to its phase transition and the ...

The Effect of Temperature on Thermochromic Leuco Dyes: A Meta-Analysis
The effect of temperature treatment, either increasing or decreasing the temperature of leuco dyes, can produce thermochromic by looking at the changing color of samples resulting from experiments. The colors that are seen namely brightness (L), a* value,

AROMATIC ALDEHYDE-LEUCO DYE PHOTOXIDATION
Tris (dimethylaminophenyl) methane leuco dyes undergo rapid photoxidation together with aromatic aldehydes. Quantum yields for dye formation in film media are ~750. A practical photoimaging system based on this chemistry was developed. The chemical aspects of sensitization, achievement of dark stability, and the rendering of the films photo-insensitive

Thermochromic effects of leuco dyes studied in polypropylene
S.363-368A series of thermochromic polypropylene foils were prepared by embedding various leuco dye-developer-solvent systems in the polymer matrix. Bisphenol A, laurylgallate, ethylgallate and p-hydroxybenzoic acid methyl ester were used as developers ...
