PURPOSE: To show excellent curability even under a mild drying condition and to obtain extremely excellent printing preservability, by providing a resin layer based on acetoacetylated polyvinyl alcohol resin and polyvinyl alcohol resin containing acrylonitrile as a copolymerizable component on a thermal recording layer.
CONSTITUTION: A resin layer based on acetoacetylated polyvinyl alcohol resin and polyvinyl alcohol resin containing acrylonitrile as a copolymerizable component is provided on a heat sensitive recording layer containing at least a color forming agent or a color developable agent for developing a color when contacted with said color forming agent. The acetoacetylation degree of the acetoacetylated polyvinyl alcohol resin is desirably within a range of 0.1W20mol% in usual, pref., 0.5W10mol%.
