Title: SEDIMENTATION FREE JET INK COMPOSITION
Abstract:
Disclosed are ink compositions, particularly jet ink compositions that have low sedimentation rates comprising a carrier, a resin, and a pigment which is a nanostructured material. The pigment has a dry particle size of about 100 nm or less. Also disclosed is an improved process of jet printing on substrates, the improvement comprising projecting a stream of droplets of the jet ink composition to the surface of the substrate and controlling the direction of the stream so that the droplets are caused to form the desired printed message on the surface.
