Colorimetric description of thermochromic printing inks
The dynamic colour of three commercial reversible thermochromic inks were studied. Thermochromic print-ing inks change their colour according to a change in temperature. The two types of thermochromic inks are based on leuco dyes and liquid crystals. The

Application of voltammetric technique to the analysis of indanthrene dye in alkaline solution
The Indanthrene Olive Green B (C.I. Vat Green 3; C.I. 69500), VG3 dye, a vat dye bearing an anthraquinonoid group and a ketonic group, can be detected by differential pulse voltammetry in alkaline solution using glassy carbon electrode.

Photophysics of an Indigo Derivative (Keto and Leuco Structures) with Singular Properties
Spectral and photophysical properties of the indigo derivative Cibalackrot in keto and reduced (leuco) forms were studied by absorption spectra, fluorescence and pulse radiolysis and compared with the structurally similar indigo.

Reactions of leuco dyes on acid activated clays
The colour formers used in carbonless copying paper consist of admixtures of primary and secondary dyes. Work was carried out in this programme both on retarding the photofading of the primary dyes and on improving the reactivity of the clay minerals ...
