  • Patent number: 5238900
    Abstract: The heat-sensitive recording material is prepared by forming on a support successively a heat-sensitive recording layer containing a color former and a color developer which forms a color by reacting with the color former, an intermediate layer obtained by coating an aqueous solution or aqueous dispersion of a resin, and an overcoat layer containing a ionizing radiation curable resin, and then irradiating an ionizing radiation. The overcoat layer contains a silicone surface active agent and a low molecular weight polyolefin resin microball. The heat-sensitive recording material is excellent in recording runnability and printability as well as in color density of the recorded images and image-retainability.
