Thermochromic inks - Functional graphic application for sustainable packaging
2012Thermochromic inks are one of the major groups of colour-changing inks. The colour change in thermochromic inks is caused by exposure to different temperature. Inks that change colour under certain circumstances are finding increasing use in applications such as security printing, brand protection or smart packaging. With thermochromic inks application,

The influence of thermochromic ink on recovered cardboard biodegradation
2016As the packaging industry is growing lately and the amount of packaging waste increases, it becomes one of the major environmental problems. Packaging waste comprising about one-third of all municipal solid waste, mainly plastic and paper based. Anaerobic degradation is one of the most environmentally friendly methods for solid organic waste treatment ...

Some experimental properties on reversibility of leucodye thermochromic inks
2009UV-curable leucodye-based inks that change colour due to a change in temperature, also know as thermochromic inks, were analysed. Inks in black, blue and red hues with an activation temperature of 31 °C were applied. The colour of thermochromic samples is not depended only on their momentary temperature but also on their thermal history, thus showing ...

Optical properties of thermochromic liquid crystal printing inks
2013Thermochromic 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 ...

Selective oxygen plasma etching of thermochromic printing inks
2010Selective etching with oxygen plasma is one of very few methods suitable for observation of pigments in dry coatings. The feasibility of this method for coating with microencapsulated organic chromogenic composite is studied here. The exposure time required to etch enough binder away is too long for particles’ polymer shells.

Functional properties of the leucodye-based thermochromic printing inks
2011Leuco dye-based thermochromic printing inks are one of the candidates for active packaging of the future. Such an advanced application requires much more knowledge about these novel inks as it is currently provided by the manufacturers. Thermochromic inks reversibly change from colored to discolored state in a certain temperature region.

Liquid crystal-based thermochromic printing inks
2018Cilj 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.
