PURPOSE: To produce a coupler sheet having satisfactory color developing property and superior soil resistance with high productivity by feeding a coating liq. to a transfer roll as a uniform curtain-shaped liq. film, transferring this film from the roll to a substrate and forming a microcapsule coating layer.

CONSTITUTION: A coating liq. 1 based on microcapsules contg. an electron donative dye is fed to a transfer roll 5 as a uniform curtain-shaped liq. film 11. This film 11 is transferred from the roll 5 to a substrate 6 and a microcapsule coating layer is formed. A coupler sheet 13 for no-carbon pressure-sensitive copying paper having satisfactory color developing property and superior soil resistance can be produced by uniform coating with high productivity.
