Recording material and recording method

摘要

A recording material is provided comprising in order: 1) a sheet-like paper substrate 2) at least one pigment layer coated thereon 3) at least one sealing layer coated thereon which comprises a particulate polymer dispersion characterised by a film forming temperature of between 60 DEG C and 140 DEG C(extend: 160 DEG C) and an average particle size between about 1 mu m and about 50 mu m together with at least one water-soluble polymer binder. The recording materials of the invention are particularly suitable for use with the ink jet printing process. There is also provided a method wherein the printed image is heated after printing to seal the sealing layer by partly melting and softening the particulate polymer dispersion sufficiently for it to form a film to provide a robust image protecting coating.
