| 摘要 |
A heat-sensitive recording material is described, comprising a heat-sensitive recording layer containing an electron-donating colorless dye and an electron-accepting compound, said heat-sensitive layer being provided on a support member, and said heat-sensitive layer containing from 5 to 50% by weight, based on the total weight of the heat-sensitive layer-constituting components, of polymer particles having an average particle size of from 0.03 to 16 microns, selected from the group consisting of ethylene- alpha -olefin copolymer particles, low density polyethylene particles, and ethylene-vinyl acetate copolymer particles.
