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 Eof microcapsule imaging sheets and prevents premature exposure of microcapsule imaging sheets in stacked media.
