- a leveling coating process selected from the list, comprising: Waizenstreichwerk, doctor blade and (roll) doctor blade coating.
- the intermediate layer (2) can make a positive contribution to the leveling of the substrate surface, which reduces the amount to be applied for the second coating composition for forming the heat-sensitive recording layer (3).
- Subsequent drying of the coating composition to form the Intermediate layer (2) is usually done by supplying heat, as done by hot-air floating dryer or contact dryer. Also proven is a combination of hot-air floatation dryer and contact dryer.
- a preferred range of between 5 and 20 g / m 2 and even better between 7 and 12 g / m 2 has proved successful.
- an intermediate layer between the web-shaped substrate (1) and the heat-sensitive recording layer (3) is used instead of the hollow body pigments having intermediate layer (2), which has no hollow body pigments but inorganic pigments, wherein the inorganic pigments preferably selected singly or in combination with one another from the list, comprising: natural or calcined kaolin, silicon oxide and here in particular bentonite, calcium carbonate and aluminum hydroxide and here especially boehmite.
- paper and here especially a non-surface treated base paper is the substrate that has prevailed on the market with regard to good environmental compatibility because of good recyclability and in the According to the invention is preferred.
