Abstract:
1. A method for producing thermosensitive recording material comprising a carrier substrate as well as a thermal reaction layer comprising a color former and a color developer, in particular for producing a thermal paper, whereby during the method a suspension is applied to the carrier substrate containing the starter material for the thermal reaction layer, the carrier substrate with applied suspension is dried and passed through a smoothing mechanism for smoothing purposes, characterized in that the dried carrier substrate with applied thermal reaction layer is passed for smoothing purposes through a shoe calender, in which the dried carrier substrate with applied thermal reaction layer is pressed extensively against a roller by means of a pre-determined contact pressure, and wherein the dried carrier substrate with applied thermal reaction layer, before being smoothed in the shoe calendar, is moistened on the back, remote from the thermal reaction layer, and the moistened carrier substrate and the applied thermal reaction layer are additionally dried before being smoothed in the shoe calender.
