A multilayer coating film includes a lustrous layer containing a luster material and a blackish coloring agent, and a colored layer containing a reddish coloring agent, and having translucency. A slope of a tangent of a spectrum of a spectral transmittance, defined as an absolute value, of the colored layer at the wavelength of 620 nm is 0.02 nmor more and 0.06 nmor less, the spectral transmittance being obtainable by dividing a spectral reflectance measured for the colored layer stacked on the lustrous layer at the light receiving angle of 15° in the case of the light incident angle of 45°, by a spectral reflectance measured for the lustrous layer from which the colored layer is removed and a surface of which is therefore exposed, at the light receiving angle of 15° in the case of the light incident angle of 45°.

Multilayered coating film and coated article

A multilayer coating film includes a lustrous layer containing a luster material and a colored layer containing a reddish coloring agent, and having translucency. Regarding a Y value of an XYZ colorimetric system calibrated with a standard white plate, when a light incident angle is 45°, Y(5°) represents a Y value of reflected light measured at a light receiving angle of 5°, and Y(15°) represents a Y value of reflected light measured at a light receiving angle of 15°, the lustrous layer satisfies the following: Y(5°) is 30 or more to 700 or less; Y(15°)=k×Y(5°) (where k is a coefficient); and k is 0.01 or more to 0.3 or less. The concentration of the reddish coloring agent in the colored layer is 1 mass % or more to 17 mass % or less.

Provided is a material having an excellent sound-absorbing performance which can be easily applied to the desired area at the operation site and which can effectively prevent sound leakage. The material includes an open-cell soft polyurethane foam prepared from a 2-part reactive urethane resin composition prepared from a polyisocyanate component and a polyol-containing component,

2-part reactive urethane resin composition and method for producing thereof

An application apparatus includes a nozzle device () injecting a damping material from a nozzle hole () to a vehicle body, an articulated robot () moving the nozzle device () relative to the vehicle body, a supply section including a supply pump (), and a supply passage (), and continuously driving the supply pump () to continuously supply the damping material from the supply pump () to the supply passage () in a substantially uniform amount, a return passage () branched from the supply passage () and returning the damping material to the supply pump (), and a gun () and a return valve () switching a supply destination of the damping material between the nozzle hole () and the return passage () based on information on applying the damping material to the vehicle body.
