Abstract:
The present invention relates to a method for forming a multilayer coating film, the method comprising sequentially applying a colored coating composition (X), an effect pigment dispersion (Y), and a clear coating composition (Z) to a substrate to form an uncured colored coating film, an uncured effect coating film, and an uncured clear coating film, respectively, and heating the uncured colored coating film, the uncured effect coating film, and the uncured clear coating film to simultaneously cure these three coating films, thereby forming a multilayer coating film; wherein the effect pigment dispersion (Y) contains water, a specific surface modifier (A), a flake-effect pigment (B), and a viscosity modifier (C); and a film obtained by applying the effect pigment dispersion (Y) to a dry film thickness of 0.2 μm has a light transmittance at a wavelength of 550 nm of 10 to 50%.

Claim (Index 1):
A method for forming a multilayer coating film by sequentially performing the following steps (1) to (4):\n (1) applying a colored coating composition (X) to a substrate to form a colored coating film, (2) applying an effect pigment dispersion (Y) to the colored coating film formed in step (1) to form an effect coating film, (3) applying a clear coating composition (Z) to the effect coating film formed in step (2) to form a clear coating film, and (4) heating the uncured colored coating film, the uncured effect coating film, and the uncured clear coating film formed respectively in steps (1) to (3) to simultaneously cure these three coating films; wherein the effect pigment dispersion (Y) contains water, a surface modifier (A), a flake-effect pigment (B), and a viscosity modifier (C), the surface modifier (A) has a contact angle of 8 to 20\u00b0 with respect to a previously degreased tin plate (produced by Paltek Corporation), the contact angle being measured in such a manner that a liquid that is a mixture of isopropanol, water, and the surface modifier (A) at a ratio of 4.5/95/1 is adjusted to have a viscosity of 150 mPa\u00b7s measured by a B-type viscometer at a rotor rotational speed of 60 rpm at a temperature of 20\u00b0 C., 10 \u03bcL of the liquid is added dropwise to the tin plate, and the contact angle with respect to the tin plate is measured 10 seconds after dropping, and a film obtained by applying the effect pigment dispersion (Y) to a dry film thickness of 0.2 \u03bcm has a light transmittance at a wavelength of 550 nm of 10 to 50%.
