Abstract
A process for the production of heat-sensitive recording materials is described, comprising the steps of (1) applying to a support a coating composition comprising a color former, a color developer, and at least one of a water-soluble binder and a water-dispersible binder, to form a layer, and (2) irradiating the layer with electron beams. Images recorded on the heat-sensitive recording material exhibit superior stability. The color density of the recorded images remains stable even when the recording material is moistened with water or placed in a high humidity atmosphere. Further, even moistened recorded images do not disappear when rubbed with a finger.
