Coating method.

摘要

A method of applying a coating fluid 5 with a coating head 1 having a front edge 3 and a back edge 4 receding in a direction opposite to the support from the front edge in a liquid seal state with a precoat fluid 7 of low viscosity consisting essentially of an organic solvent previously applied to the application face of the support 2. The coating fluid 5 is spouted from a slot at the rear of the front edge while the coat thickness of the precoat fluid is adjusted by setting the run speed of the support to 400 m/min or higher, the curvature R (mm) of the top surface of the front edge as a curved surface to 1 </= R </= 5, tension of the support, T (kg/m), to 10 </= T </= 30, and the incidence angle of the support on the front edge, alpha , to the range of -0.5 DEG to 2 DEG . <IMAGE>
