Abstract
The problem to be solved by the present invention is to provide a method for forming a multilayer coating film capable of forming a red-based multilayer coating film having high chroma and an excellent sense of depth and weatherability. The present invention provides a method for forming a multilayer coating film comprising the steps of (1) applying a first colored coating composition comprising an organic red pigment to form a first colored coating film having a hue such that the hue angle h in the L*C*h color space diagram is within the range of 23±3°, (2) applying a second colored coating composition comprising an organic red pigment to the first colored coating film to form a second colored coating film having a hue such that the hue angle h in L*C*h color space diagram is within the range of 35±5°, and (3) applying a clear coating composition to the second colored coating film to form a clear coating film; wherein the color difference ΔE between the first colored coating film and the multilayer coating film obtained by Steps (1) to (3) is within the range of 20 to 30.
