ABSTRACT:
A base paper for use in the manufacture of printing paper used in low heat thermal printing operations. The base paper is provided by coating a paper sheet with a dispersion comprising hollow gas-containing spherical particles preferably of a synthetic polymer, a filler of clay particles, and a binder. The coating provides pigment, thermal insulation and aqueous holdout for a thermosensitive recording layer applied onto the coating and can be calendered to improve surface smoothness.
