Abstract:

In the present invention, an aqueous dispersion liquid of a poly(hydroxyalkanoate) resin is applied onto a substrate to form an applied film, and then, the applied film is heated with superheated steam such that the surface temperature of the applied film reaches a temperature that is 10°C to 100°C higher than the melting point (Tm) of the poly(hydroxyalkanoate) resin, allowing the poly(hydroxyalkanoate) resin to fuse to form a resin layer.
