An object of the present invention is to provide a heat-sensitive recording material which has high gloss of a whitish paper portion and a printing portion, excellent color development sensitivity and excellent running property, and particularly excellent in high-speed printing runability. A heat-sensitive recording material comprising, on a support, a heat-sensitive recording layer containing an electron-donating leuco dye and an electron-accepting color developing agent which are colorless to pale in sequence, an intermediate layer and a glossy layer as an outermost layer, wherein the intermediate layer contains a carboxyl- Wherein the gloss layer contains a long-chain alkyl group-containing resin and an emulsion-type silicone copolymer resin. The long-chain alkyl group-containing resin is preferably a long-chain alkyl group-containing acrylic resin, and the silicone copolymer resin is preferably a silicone-acrylic copolymer resin or a silicone-urethane copolymer resin. |
