Definitions

the coating method of an extrusion type can conduct simultaneous multi-layer coating on the so-called wet-on-wet basis, and it is extremely effective in terms of cost and performance for the application to manufacture recent coated products with high value added.
a method to form the aforesaid coated layers of a multi-layer type by coating a coating solution and drying it for each layer on the substrate to be coated, as disclosed in TOKKAISHO Nos. 51-119204, 52-51908 and 53-16604. In this method wherein steps of coating and drying are repeated, however, there have been problems that productivity is poor and it is difficult to make the uppermost layer to be thin. So, TOKKAISHO Nos.
the inventors of the invention found that no dust is caught between the tip of a coater and a substrate to be coated, resulting in no occurrence of streak defects, and a substrate to be coated, when it is flexible, does not affect the coating, and thereby thin-layer coating is possible, when extruding a coating solution in a shape of an extremely thin layer by narrowing slit outlet clearance d of the coater to 50 ⁇ m or less, preferably 18 ⁇ m or less which is much narrower than that of the conventional extrusion type coater, and thereby coating by colliding the extruded coating solution film with a substrate to be coated which is conveyed or held to be away from the coater by the distance that is greater than that for the conventional extrusion type coater. It has also been cleared in this coating method that coating can be carried out independently of the coating speed once an extruded solution layer is formed, and the higher the coating speed is, the thinner the solution layer is, resulting in a thinner layer coating.
a contact angle to be 45° or more by making surface roughness Rmax to be 0.8 ⁇ m or less, preferably to be 0.1 ⁇ m or less, in a surface grinding method.
