Abstract
In the condition that a support is liquid-sealed with a precoat solution mainly containing a solvent and being applied onto the coating surface of the support in advance, a coating composition, prepared by dispersing powder of a mean particle size not larger than 0.4 .mu.m, is applied so as to be laminated onto the precoat solution by means of an extrusion head. The extrusion head has a front edge located at the upstream side with respect to the direction of movement of the support, and a back edge located at the downstream side with respect to the direction of movement of the support so that an end of the back edge retreats farther from the support with a difference in level than the front edge. The wet film thickness of the precoat solution is made to be in a range not larger than 1/3 of the wet film thickness of the coating composition. A coating method in which the surface quality of a coating film formed on a surface of a support can be improved is therefore provided.
