Beschreibung
Zusammenfassung:	The invention concerns printing inks, particularly for screen printing. The inks consist of a water-in-oil emulsion, the non-aqueous phase including a radiation curable component and a transparent pigment. Such inks have shown high screen stability with good cure speed, combined with low printed film weight compared with prior art radiation curable inks. Conventional radiation-curable components can be used, for example they can include one or more reactive oligomers, unsaturated monomers and photoinitiators or photochemical cross-linking agents. Examples of pigments include azo and diazo condensation pigments.
