METHOD FOR APPLYING A COMPOSITION TO A SUBSTRATE AND COMPOSITION FOR USE THEREIN

摘要

The present invention provides a process for applying a molten thermoplastic composition as a series of discrete droplets from a non-contact ink jet printing apparatus to form separate drops on a substrate moving relative to the apparatus, characterised in that the molten composition is thermally stable at the temperature of application and is applied at a temperature in excess of 100.degree.C. The invention can be used to apply the molten composition to a variety of substrates using on-demand or continuous non-contact ink jet application techniques. However, the invention is of especial use in applying thermoplastic inks to nonporous substrates using an on-demand ink jet printer.
