  • Multi-layer coating film formation method
    Patent number: 10610889
    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 ?m has a light transmittance at a wavelength of 550 nm of 10 to 50%.
    Type: Grant
