Primers with improved reflective and thermally insulative properties for microcapsule imaging system

Primer layers having improved reflectivity and thermal insulation properties are provided for use in microencapsulated thermal imaging sheets. Primer layers having a polymeric binder, of about 3% to about 60% by weight, relative to the total weight of the primer layer, of a white particulate, a prim...

Beschreibung
Zusammenfassung:	Primer layers having improved reflectivity and thermal insulation properties are provided for use in microencapsulated thermal imaging sheets. Primer layers having a polymeric binder, of about 3% to about 60% by weight, relative to the total weight of the primer layer, of a white particulate, a primer substrate, and hollow particulate particles improve the reflectivity, color development, color density, and thermal insulation of microcapsule imaging sheets including the same. A black back-coat applied to the substrate on a side opposite the primer layer further enhances the Dmax and E10 of microcapsule imaging sheets and prevents premature exposure of microcapsule imaging sheets in stacked media.
