Abstract
A method for coating a running support with a coating solution, such as in the production of a magnetic recording medium, in which spreading of the coating solution into edge portions of the support not intended to be coated with the coating solution is prevented, hence providing a coating layer uniform in thickness and with good surface characteristics. Immediately before application of the coating solution to the support, a solvent is applied to regions of the support which are not to be coated with the coating solution and which are located on both sides of the coating region to be coated with the coating solution. In accordance with the invention, the solubility parameter of the solvent is made different from that of a solvent contained in the coating solution by at least 1.2 at a temperature of 25.degree. C.
