Abstract
Official abstract text for this publication.
The purpose of the present invention is to obtain a method for forming an excellent multi-layer coating film of high chroma and brightness and a rich color. With the method, color mottling does not occur easily in the coating film and the design obtained is homogeneous even without strict control of variations in film thickness during coating. The method for forming the excellent multi-layer coating film comprises: forming a metallic base coating film on the surface of the object to be coated by applying a metallic base coating containing a shiny material; then forming a color base coating film by applying a color base coating; subsequently forming a clear coating film by applying a clear coating on the color base coating film; and heat-curing the metallic base coating film, the color base coating film and the clear coating film obtained. In the method, the light reflectance of the metallic base coating film is in a specified range and the light transmittance of the single color base coating film obtained by heat-curing the color base coating film as a single film is adjusted to a specified range.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for forming a multi-layer coating film comprising the steps of: (1) applying a metallic base coating composition to a coating substrate to form a metallic base coating film, wherein the metallic base coating composition comprises a coloring pigment and a luster pigment, wherein the coloring pigment in the metallic base coating composition is a perylene pigment, and the perylene pigment is a perylene red pigment, and wherein the coloring pigment…
