  • Patent number: 8362104
    Abstract: The invention relates to a method for the production of a digital printing ink and to the ink thus obtained. The inventive method comprises the following phases consisting in: dispersing pigments in a mixture of oligomers and monomers, including polyol acrylates, with a maximum particle size of 1 micrometer; diluting same with a mixture of monofunctional and multifunctional acrylic monomers until a viscosity of between 10 and 30 centipoise is obtained; introducing a photoinitiator system, which starts the polymerization of the oligomers and monomers from the first phase, in the presence of ultraviolet radiation; and subjecting the resulting ink to a filtration process.
