PURPOSE:To avoid troubles in feeding paper such as sticking, by a method wherein the coefficient of static friction between a surface of a color forming layer and an opposite side surface of a base is set to be not lower than 0.40, in a heat-sensitive recording material comprising a heat-sensitive color forming layer comprising a color forming substance and a color developer as main constituents. CONSTITUTION:A paper so made as to have a low density is used as the base, or a friction factor adjusting material such as calcium carbonate, clay or talc is applied to a surface of the base on the opposite side of the color forming layer, whereby the coefficient of static friction between the surface of the color forming layer and the opposite-side surface of the base is set to be not lower than 0.40. Further, the coefficient of static friction between recording surfaces is preferably not lower than 0.45, and that between base surfaces is preferably not lower than 0.25. |
