This invention provides a heat-sensitive record material comprising a base sheet and a heat-sensitive record layer formed over the base sheet and containing a color forming material and a color developing material which undergoes a color forming reaction on contact with the color forming material, the heat-sensitive record material being characterized in that a resin coating layer cured with electron beam is formed over the heat-sensitive record layer; and also a heat-sensitive record material comprising a base sheet and a heat-sensitive record layer formed over the base sheet and containing a color forming material and a color developing material which undergoes a color forming reaction on contact with the color forming material, the heat-sensitive record material being characterized by a resin coating layer cured with electron beam, formed over the heat-sensitive record layer and containing about 5 to about 300 parts by weight of a pigment per 100 parts by weight of the resin.
A heat-sensitive record material comprising a base sheet and a heat-sensitive record layer formed over the base sheet and containing a color forming material and a color developing material which undergoes a color forming reaction on contact with the color forming material, the heat-sensitive record material being characterized in that a resin coating layer cured with electron beam is formed over the heat-sensitive record layer by applying a coating composition to the record layer and curing the coating with electron beam, the coating composition comprising at least one oligomer liquid at room temperature, capable of giving a uniform smooth uncured resin coating when applied and forming a cured resin film when irradiated with electron beam, and having at least one ethylenically unsaturated bond in the molecule.
