  • Method for producing thermosensitive recording material and recording material produced according to said method
    Patent number: 7833573
    Abstract: The invention relates to a method for producing thermosensitive recording material, comprising a carrier substrate and a thermal reaction layer containing a color former and a color developer. According to the invention, an application suspension, containing the starting materials of the thermal reaction layer, is applied to the carrier substrate and the carrier substrate is subsequently dried with the applied application suspension. Then the dried carrier substrate with the applied thermal reaction layer is guided through a smoothing mechanism in order to be smoothed, wherein the dried carrier substrate with the applied thermal reaction layer is pressed extensively against a roller by means of a predetermined contact pressure. The invention also relates to a recording material which is produced according to the inventive method.
