PURPOSE:To improve color development density of a printing image and printing clarity, by a method wherein an upper sheet whose surface is provided with a specific heat sensitive layer and its rear is provided with a specific pressure sensitive and heat sensitive layer and protective layer, and a lower sheet whose surface is provided with the heat sensitive layer are combined with each other. CONSTITUTION:A dispersion liquid wherein a color development agent 2 is pulverised and finely dispersed within a water-soluble binder and a dispersion liquid wherein a developer 3 and water-soluble binder are pulverised and finely dispersed within water are mixed up with each other and a heat sensitive layer liquid is prepared. A heat-meltable substance 4, color development agent 2 fine powder, micro-capsule containing the color development agent 2 are mixed up with each other, which is heated, melted and pressure sensitive and heat transfer layer liquid of a uniform dispersion liquid is prepared. An ultraviolet curing ink is applied onto a pressure and heat sensitive transfer layer formed by applying the pressure sensitive and heat transfer layer liquid to the rear of a base sheet 1 for drying by relief printing after formation of heat sensitive layer by applying heat sensitive layer liquid to the surface of the base sheet 1 for drying, which is cured, to which an overcoat protective layer 5 is laminated and an upper sheet I is obtained. The upper sheet I and a lower sheet II possessing a layer containing the developer 3 on the base sheet 1 are combined with each other. |
