  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.

  本发明的目的是提供一种形成多层涂膜的方法，该涂膜具有优异的性能，例如耐酸性，它使用的涂层组合物完全不同于传统的透明涂层组合物，并且比传统的非三聚氰胺固化型、酸/环氧型和异氰酸酯型透明涂层组合物便宜。 一种形成多层涂膜的方法，包括涂布基底涂层组合物的步骤（1）和在步骤（1）中形成的涂膜上涂布透明涂层组合物的步骤（2）、 其中透明涂层组合物通过羟基和烷基酯基之间的酯交换反应引起固化反应。
