The present invention provides a jet ink composition suitable for printing on substrates such as plastics messages having abrasion resistance, the composition comprising an organic solvent, a colorant, a cellulose nitrate resin, and a rosin resin. For example, the messages printed on untreated low density polyethylene and polypropylene substrates have improved rub resistance and scratch resistance. The present invention further provides a method for printing abrasion resistant messages on a surface comprising projecting a stream of droplets of the jet ink composition to the surface, controlling the direction of the stream so that the droplets are caused to form the desired printed messages, and allowing the messages to dry. |
