Sažetak
Thermochromic liquid crystal inks (TLCs) reflect incident light in a rather narrow spectral region. This phenomenon is caused by selective reflection of light on chiral (twisted) molecular structure which changes its distribution with temperature. The reflected light produces iridescent colour which is continuously shifted from red to blue part of the spectrum with temperature, the effect which is known as „colour play“. This research is focused on the optical properties of a water-based TLC ink. The ink was screen-printed over black and white matte uncoated paper. The temperature dependent iridescent colours are seen very clearly when the ink is printed over black background, while on the white substrate is hardly visible. The observed effects were quantified by spectral reflectances applying (45°:0°) and (8°:di) geometries in the 400-700 and 200-1500 nm spectral regions, respectively. The measured temperature dependent iridescent colours were analyzed.
