Abstract
The present invention relates to a coating composition comprising an aqueous dispersion of a binder and first and second core-shell polymer particles having aqueous neutralized acid cores, wherein the first core-shell polymer particles have a diameter in the range of from 1.0 ¼m to 1.8 ¼m; the second core-shell polymer particles have a diameter in the range of from 0.25 ¼m to 1.0 ¼m; the number ratio of the second to the first core-shell polymer particles is in the range of from 1:1 to 20:1; the diameter of the second core-shell polymer particles is in the range of from 15 to 65% of the diameter of the first core-shell polymer particles; the dry bulk density of the first core-shell polymer particles is in the range of 0.25 to 0.5 g/mL; and the dry bulk density of the second core-shell polymer particles is in the range of 0.30 to 0.90 g/mL. The composition of the present invention is useful as an undercoat layer for a thermosensitive recording material.
