Abstract
The present invention relates to a method for forming a coating film including a step 1 of applying a liquid composition I containing a solvent A, a solvent B, and a polymer C to a base material; and a step 2 of applying droplets of a liquid II containing water to the liquid composition I on the base material as applied in the step 1, wherein a boiling point of the solvent A is lower than 99° C., and a distance Ra of the Hansen solubility parameter of the solvent A to water is 36 or less; a boiling point of the solvent B is 150° C. or higher, and a distance Ra of the Hansen solubility parameter of the solvent B to water is 40 or more; and the solvent B is compatible with the solvent A, the polymer C is soluble in the solvent Abut insoluble in the solvent B, and an average diameter d of the droplets applied in the step 2 is 0.01 μm or more and 50 μm or less.
