ABSTRACT:
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.
