A RADIATION CURABLE INK JET INK AND A METHOD FOR PRINTING A SUBSTRATE WITH THIS INK

摘要

The invention pertains to a radiation curable hot melt inkjet ink, comprising a carrier composition that comprises one or more radiation curable compounds and an agent that is able to reversibly gel the carrier composition, which agent is soluble in the carrier composition at a jetting temperature of the ink and creates the gelled carrier at a temperature below the jetting temperature, characterised in that the gelled carrier composition is a thixotropic composition which has a recovery time of more than 60 seconds after the gel has been mechanically disturbed to lower it's viscosity. The invention also pertains to a method for printing a substrate with this radiation curable ink.
