HEAT-SENSITIVE RECORDING MATERIAL AND METHOD FOR MANUFACTURING THE SAME

摘要

Disclosed is a heat-sensitive recording material in which an intermediate layer and a heat-sensitive recording layer that develops color due to heat are sequentially stacked on a support body, wherein the intermediate layer contains a hollow resin having the shape of a bellow, and the smoothness of a coloring surface side which is measured by Parker Print Surf is 1.0 um or less. The intermediate layer is formed by coating the support body with a coating liquid containing thermally expandable resin particles, then temporarily performing drying at a temperature lower than the expansion initiation temperature of the thermally expandable resin particles, and thereafter performing heat molding. The heat-sensitive recording layer is prepared by coating the intermediate layer with a heat-sensitive recording component that develops color due to heat.
