Abstract

<p>Among various inkjet inks for industrial use, UV curable inks are characterized by high coating strength and quick drying, and are widely used for printing on non-permeable substrates such as plastics, metals, and glass. When formulating UV inks cured by radical photopolymerization method, an acrylate compound is generally used as a monomer material as a main component. In order to have a viscosity low enough to be compatible with the ink jet system, monomer materials need to have a low molecular weight. However, low molecular weight acrylate compounds exhibit toxicity including skin sensitization in most cases. Ricoh has been developing UV curable inkjet inks that exhibit lower than ever toxicity from the viewpoint of reducing the physical burden on manufacturing site workers. In this paper, we introduce application examples of UV curable inkjet inks using methacrylate compounds and also introduce newly discovered acrylamide compounds.</p>
