METHOD FOR FORMING MULTI-LAYER METALLIC COATING

WIPO Patent Application WO/1997/047396

A1

A method for forming a multi-layer metallic coating, characteirzed by forming a metallic coating by the three-coating system wherein a first organic solvent-base, thermosetting metallic base coating composition (A) having substrate opacifying properties, containing a neutralization product of a carboxylated resin having an acid value of 5 to 100 mg KOH/g, an amino resin, and a metallic pigment, and having, in the form of a 15 'mu'm-thick cured coating, a transmittance of not more than 3 % for light having a wavelength in the range of 400 to 700 nm, a second transparent aqueous thermosetting base coating composition (B) having, in the form of a 15 'mu'm-thick cured coating, a transmittance of 10 to 95 % for light having a wavelength in the range of 400 to 700 nm, and an organic solvent-base thermosetting clear coating composition (C) are successively applied onto a metallic object coated with a cationic electrocoating agent. The method for forming a metallic coating can provide a multi-layer metallic coating possessing more excellent decoration, smoothness and other properties on a metallic coated object.
