  • Multilayer coating film structure and method for forming multilayer coating film
    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.
