Deinkability of thermochromic offset inks

Nordic Pulp & Paper Research Journal, 2016
This 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 ...

Some experimental properties on reversibility of leucodye thermochromic inks

open access: closed, 2009
UV-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 ...

Colorimetric properties of reversible thermochromic printing inks

Dyes and Pigments, 2010
The 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
