Abstract:
A coating method for coating a conveyed support with a coating solution suitable for producing a light-sensitive photographic material by letting said coating solution flow down between a first edge guide and a second edge guide so as to form a curtain layer of said coating solution, comprisingsupplying said coating solution from a slit along a slide surface which is inclined at a predetermined angle to the horizontal,supplying a first auxiliary solution from a first solution injector on a first side plate which is provided on a first edge of said slide surface at a flow rate between 0.3 cc/min and 3.0 cc/min, andsupplying a second auxiliary solution from a second solution injector on a second side plate which is provided on a second edge of said slide surface at a flow rate between 0.3 cc/min and 3.0 cc/min,wherein said first edge guide is provided on said first edge, and said second edge guide is provided on said second edge,a value of surface tension of said first auxiliary solution and said second auxiliary solution being not smaller than a minimum value of surface tension of said coating solution,a viscosity of said first auxiliary solution and said second auxiliary solution being smaller than a viscosity of said coating solution.
