摘要：This invention provides a method for forming multilayer coating film, whichcomprises successively carrying out a step of applying an intermediate paint onto acoating object to form an intermediate coating film; a step of forming a base coating filmby applying onto the intermediate coating film a water-based base coating paint; a stepof forming a clear coating film by applying onto the base coating film a clear coatingpaint, and a step of heating the uncured intermediate coating film, base coating film andclear coating film to simultaneously cure these three coating films; wherein theintermediate paint has a complex viscosity at 40° C. (η*) of not higher than 100 Pa·secunder the conditions of shear stress, 1.0 Pa and frequency, 0.1 Hz, and a complex viscosityat 80° C. (η*) of at least 800 Pa·sec under the conditions of shear stress, 1.0 Pa andfrequency, 0.1 Hz.
