Patent

CA 2589784

The present invention provides a thermal paper composite precursor comprising (a) a substrate layer; and (b) a base layer positioned on the substrate layer, the base layer comprising a binder and at least one porosity improver wherein the thermal paper composite precursor has a thermal effusivity that is at least about 2% less than the thermal effusivity of porosity improver-less thermal paper composite precursor. The thermal paper composite precursor is useful in making thermal paper composite.

L'invention concerne un précurseur composite de papier thermique comprenant (a) une couche de substrat et (b) une couche de base placée sur la couche de substrat, la couche de base comprenant un liant et au moins un renforçateur de porosité. Ce précurseur composite de papier thermique possède une effusivité thermique qui est au moins environ 2 % inférieure à l'effusivité thermique du précurseur composite de papier thermique dépourvu de renforçateur de porosité. Ce précurseur composite de papier thermique est utile dans la fabrication de composite de papier thermique.
