Method for forming multilayer coating film

A method of forming a multilayer coating film comprising:

• forming a first base coating film by coating a first base coating composition containing a colored pigment and a photoluminescent pigment on an object to be coated;
• forming a second base coating film by coating a second base coating composition containing a colored pigment and a photoluminescent pigment on the object to be coated that has undergone the first base coating composition application step;
• applying a top clear coating composition on the object to be coated that has undergone the second base coating composition application step;
• and
• heating and curing the uncured coating films on the object to be coated, wherein
• a pigment weight concentration (PWC) of the photoluminescent pigment in the second base coating composition is from 0.01 to 1.1% by mass,
• the first base coating film formed from the first base coating composition has a light reflectance of from 10 to 30% in a wavelength region corresponding to a paint color of the multilayer coating film in a wavelength of from 400 to 700 nm, and
• the second base coating film formed from the second base coating composition has a light transmittance of from 60 to 90% in the wavelength region.
