Method of producing multilayer coating film

Abstract

Provided is a method of producing a multilayer coating film, the method including the steps of: turning multiple coating liquids into multiple layers in advance; and transferring the coating liquids turned into multiple layers onto a substrate, in which a mixing-preventing component that prevents two kinds of coating liquids which contact each other from mixing with each other is added to at least one of the two kinds of coating liquids in advance, and molecules of the mixing-preventing component are localized toward a vicinity of an interface between layers of the coating liquids so that the interface between layers is secured. The production method includes producing a multilayer coating film having good interlayer adhesiveness with ease and good productivity, by collectively applying multiple coating liquids without using a gelling agent or the like for modifying the viscosity of each coating liquid to be laminated.
