  • Patent number: 10071396
    Abstract: A laminated coating film (2) includes a metallic base layer (4) and a color clear layer 5, and produces a target color with the metallic base layer 4 and the color clear layer (5). The laminated coating film (2) is designed to have high chroma at the highlight, and further to provide an appearance of denseness. To address this, the laminated coating film satisfies the following formula (1): (RH(P)/RH(OA))>60??(1) where RH(P) represents a highlight reflectance of light of the target color, and RH(OA) represents an average highlight reflectance of light in a wavelength range outside a hue range of the target color.

  • Patent number: 9737906
    Abstract: 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.

  • Patent number: 9630212
    Abstract: A method of forming a multi-layer paint film comprising coating an aqueous first colored base paint (A) on an electro-deposition paint cured paint film to form a first colored base paint film, coating an aqueous second colored base paint (B) on the first colored base paint film without preliminary heating of the first colored base paint film to form a second colored base paint film, coating a clear paint (C) coated on the second colored base paint film after preliminary heating of the first paint film and second paint film to form a clear paint film, and heating and curing the three paint films at the same time, wherein a talc pigment is included in each of paint (A) and paint (B) in an amount of from 1 to 5 mass % with respect to the total resin solid fraction of each of paint (A) and paint (B).

  • Patent number: 9296016
    Abstract: A double-structure coated object includes an outer plate portion configured to produce a target color by stacking a coating film of a first paint and a coating film of a second paint, and an inner plate portion on which a coating film of the second paint is formed. When the coating film is formed on the inner plate portion, and then the first paint and the second paint are sequentially applied to the outer plate portion, paint dust on the inner plate portion is prevented from causing viewers to feel something different about color. To achieve this, the ratio (1BC)/(1BC+2BC) of the spectral reflectance (1BC) of the color of the coating film made of the first paint to the spectral reflectance (1BC+2BC) of the target color is configured to fall within a predetermined range.

    Abstract: The average light transmissivity of a wavelength range of 300 through 390 nm of upper-layer coating films is less than 0.5% and the average light transmissivity of a wavelength range of 390 through 450 nm of those is 6.5% or less. Or, the average light transmissivity of the wavelength range of 300 through 390 nm of the upper-layer coating films is 0.5% or more and the average light transmissivity of the wavelength range of 390 through 450 nm of those is 4.5% or less. Accordingly, the deterioration resistance against lights can be improved without forming any second coating film in a multi-layer coating film structure comprising the upper-layer coating films formed on a lower-layer coating film formed by an electrocoating or the like.
