PURPOSE:To obtain the heat sensitive recording material, which is provided on a paper supporting body for forming a heat sensitive coloring layer, on which thermoplastic resin or thermosetting resin is applied as an undercoat, and which is characterized by the surface of the paper having few unevenness, the uniform surface of the heat sensitive recording layer, excellent heat conductivity, and improved sensitivity. CONSTITUTION:On the surface of the supporting body comprising the paper such as high quality paper, the thermoplastic resin (e.g. polyamide, ABS resin, polyacrylate, and the like) or thermosetting resin (e.g. phenol resin, unsaturated polyester resin, and the like) is applied as e.g. aqueous solution and the like, and dried, and the undercoat layer is formed. Thereafter, the heat sensitive coloring layer including a coloring component comprising a coloring material and acidic material or phenolic material which colors said coloring material by heat is formed on the undercoat layer. |
