Colorimetric description of thermochromic printing inks
Acta graphica : znanstveni časopis za tiskarstvo i grafičke komunikacije, 2017 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 thermochromic effect achieved by liquid crystals is quite different from the effect achieved with ...
