摘要： The invention relates to a method for producing theromsensitive recording material, comprising a carrier substrate and a thermal reaction layer containing a colour former and a colour 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.

摘要： The invention relates to a method for producing a thermal paper comprising a carrier substrate, an intermediate pigment coat, a thermal reaction coat and optionally one or more additional intermediate coats and/or top coats, said intermediate pigment coat being formed from a pigment, binding agents and optionally an aqueous application suspension containing additional application additives, by means of a curtain coating method. Said method is characterised in that an aqueous application suspension containing calcined kaolin, with a solid content of between approximately 25 and 75 wt. %, is applied at an operating speed of at least approximately 500 m/min in a curtain coating method and is dried. Said method is technically simple and economical to perform. In particular, the method enables the use of the curtain coating method at a higher speed of more than 750 m/min and in particular more than 1500 m/min.
