Nanopigments in offset printing inks

Comunicación presentada en 36th IARIGAI International Research Conference, Stockholm, September 2009.Nanopigments are a new type of pigment. They are hybrid materials consisting of organic dyes and layered silicate nanoparticles. Nanopigments are already applied to make polymeric coatings and they had shown improvement in mechanical, thermal and stability properties of the substrate and dyes (Batenburg and Fischer, 2001). In this work, nanopigments had been synthesized to be applied in the manufacture of offset printing inks. Therefore, four different nanopigments are pursuit: cyan (C), magenta (M), yellow (Y), and black (K), in order to obtain primary colour for a four-colour-process system
