Abstract:
An object of the present invention is to provide a method for forming a multilayer coating film with excellent performance such as acid resistance, by using a coating composition which is completely different from conventional clear coating compositions and cheaper than conventional non-melamine curing type, acid/epoxy type, and isocyanate type clear coating compositions. A method for forming a multilayer coating film comprising a step (1) of applying a base coating composition and a step (2) of applying a clear coating composition on a coating film formed in the step (1), wherein the clear coating composition causes a curing reaction through a transesterification reaction between a hydroxyl group and an alkyl ester group.
