Description	The thermochromic composites used for this study were prepared by applying crystal violet lactone as a leuco dye together with bisphenol A of different molar ratios as a developer and 1-octadecanol as a solvent. The colorimetric properties of all composites were measured during heating and cooling within a broad temperature range, which makes it possible to characterize entire colour hysteresis loops. It was demonstrated how these properties depend on the developer and solvent ratios. The investigations concentrated in particular on the total colour contrast between the coloured and the discoloured states, the temperature interval needed for the colour to change, and the width of the hysteresis loop. It was shown that composites with the same colorimetric properties could be prepared by applying a relatively broad range of dye/developer concentration ratios.
