摘要： A curtain coating method of coating a continuously travelling web with at least two kinds of coating solutions superposed upon one another in layers includes the steps of supplying said coating solutions to flow as a free falling curtain and impinging the coating solutions on the web, in which differences in gelatin concentration and viscosity between a coating solution for a lowest layer and a coating solution for an adjacent layer are adjusted to 0-2 weight percent and 0-20 cp respectively. Furthermore, a curtain coating apparatus for coating a web with a coating solution includes a hopper with a slide plane on which the coating solution flows and with a hopper lip from where the coating solution begins to freely fall down as a free falling curtain, and at least a pair of outlets which are each disposed in a position along the edge part of the free falling curtain and situated in a fixed distance down from the hopper lip, in which the auxiliary solutions are introduced from the width directions so as to maintain the curtain in the width direction thereof.
