Abstract
A composition, preferably a synthetic paper, is disclosed comprising a plastics substrate having a printable polymer coating, wherein the coating has a density of from 0.3 to 0.7 g/cm3. The low density provides improved adhesion and printability properties compared with the prior art, and permits the coating to be applied in a single layer of uniform density.
Claims15
A printable medium which is a synthetic paper comprising a plastics substrate having a printable polymer coating, wherein the plastics substrate is formed from an orientable thermoplastics olefin polymer that is biaxially oriented, with a 3–5:1 stretch in each of the machine and transverse directions, and the coating is in the form of a single layer of uniform density and has a density of from 0.3 to 0.8 g/cm3.
A printable medium comprising a plastics substrate having a printable polymer coating, wherein the coating has a density of from 0.3 to 0.8 g/cm3 and includes an ionic or polyanionic insolubilizing agent that comprises ammonium zinc carbonate, disodium tetraborate or ammonium zirconium carbonate.
A printable medium comprising a plastics substrate having a printable polymer coating, wherein the plastics substrate is formed from a composition comprising a copolymer of HDPE, rosin derived voiding agent, polystyrene, HDPE homopolymer, calcium carbonate filler, titanium dioxide, styrene butadiene and calcium oxide, and the coating has a density of from 0.3 to 0.8 g/cm3.
