似塑性液体を使用するようにしたものであった。Furthermore, Japanese Patent Application Laid-Open No. 54-1350 discloses that the next layer to the web is 20 to 200 cps at a sliding speed of 100 seconds.
A method has been proposed that utilizes a dilute carrier layer of a pseudoplastic liquid with a viscosity of less than LO cps and a shear rate of too, ooo seconds. That is, in order to improve the instability of the bead portion as described in Japanese Patent Publication No. 56-20534 I, this coating method has a high viscosity in the bottom layer under low shear rates and a low viscosity under high shear rates. It was designed to use a pseudoplastic liquid with viscosity.

Means for Solving Problems] As a result of intensive experimental studies on a method of high-speed coating using a low viscosity liquid as the bottom layer, the inventors found that they used Newtonian flow water in the bottom layer and Surprisingly, when the wet I11 coating amount is ultra-thin with less than 2 layers per web surface IM, high-speed coating properties are not lost, and mixing between the bottom layer and the layer immediately above due to swirling in the bead is achieved. It was found that this does not occur.

が出来た。In the present invention, the bottom layer coating film is formed with water, the wet coating amount is 2 or less per 1 m2 of the web surface, and the coating amount of the layer adjacent to the bottom layer is thicker than the bottom layer and is made of water-soluble water-soluble material having a high viscosity. By forming the coating with a coating liquid composition, the web and the lowermost NWA are well wetted and the beat is stable, and there is no mixing between the eyebrows with the layer above it, and the occurrence of coating streaks etc. caused by the lowermost layer. It was possible to significantly increase the coating speed without any problems.
