Production of ink containing thermochromic dyestuff
Proceedings - The Eleventh International Symposium GRID 2022, 2022 Security inks are functional inks containing a binder and a special colorant used in money, checks and valuable documents. In security inks, thermochromic dyes, UV emitted, infrared emitted dyes can be used. Thermochromic dyestuffs provide different colors at different temperatures and ensure the requirements in the field of security.

Deinkability of thermochromic offset inks
Nordic Pulp and Paper Research Journal, 2016This paper evaluates the deinkability of thermochromic offset inks. For this purpose, three thermochromic inks were printed on white uncoated paper, in laboratory conditions. These prints were mixed in equal shares and recycled by means of chemical deinking flotation under defined conditions in the laboratory according to INGEDE method 11p ...

Colorimetric properties of reversible thermochromic printing inks
Dyes and Pigments, 2010The colorimetric properties of three, leuco dye-based thermochromic inks at 31 C activation temperature were studied. The inks had similar pigment particle size distribution and comparably thick microcapsule shells with similar stability against oxygen plasma etching. The colour of the inks was dependent on temperature as well as the thermal history of

Dynamic colorimetric properties of mixed thermochromic printing inks
Coloration Technology, 2011Leuco dye‐based thermochromic inks reversibly change from the coloured to the discoloured state in a defined, comparatively wide temperature region. Inside this region, the colour of a sample depends on the temperature and thermal history, which is known as the hysteresis effect. The colour of such a sample as a function of temperature has the shape of

Liquid crystal-based thermochromic printing inks
, 2018 Cilj predloženog istraživanja je cjelovita karakterizacija optičkih efekata termokromnih tiskarskih boja na bazi tekućih kristala. Temperaturno ovisni optički efekt ove vrste tiskarskih boja razlikuje se od konvencionalnih tiskarskih boja, ali i od termokromnih tiskarskih boja na bazi leuko bojila.

Stability of thermochromic printing inks
2010Thermochromic (TC) printing inks change their colour regarding the change in temperature. One of the most frequently used TC material in printing inks are leuco dyes. This TC composite usually consists of a colour former (leuco dye), a colour developer and a solvent, protected in polymer capsules.

Colorimetric properties of UV-thermochromic inks
2009The focus of this paper is on thermochromic inks that change colour in a controlled way when the temperature is varied. We will analyse here colorimetric properties of the screen-printed UV-curing leucodye thermochromic inks in red, blue and black shades with activation temperature of 31 °C.

Thermochromic inks – dynamic colour possibilities
2010Thermochromic inks are one of the major groups of colour-changing inks. This paper aims at discussing general aspects of thermochromic inks, dynamic colorimetric properties of leuco dye-based thermochromic inks, their stability and principle of variable-temperature colour measurement. We will analyse here a colorimetric properties of the screen-printed
