摘要： A thermosensitive recording material having a high resistance to curling and cockling when colored images are developed thereon comprises a substrate sheet comprising a thermoplastic resin and having a thermal shrinkage of 1.0% to 2.0% at a temperature of 120.degree. C.; a thermosensitive colored image-forming layer formed on a surface of the substrate sheet and comprising a colorless dye precursor, a color-developing agent and a binder; a backcoat layer formed on the opposite surface of the substrate sheet, having a weight of 1 to 10 g/m.sup.2 and comprising 20 to 90 parts by weight of a water-soluble polymeric material 10 to 80 parts by weight of a water-isoluble polymeric material and 1 to 10 parts by weight of a cross-linking agent for the water-soluble polymeric material; and optionally, an overcoat layer formed on the thermosensitive colored image-forming layer and comprising a pigment and binder resin.
