Abstract: FIELD: paint industry. 
     SUBSTANCE: invention relates to a multilayer coating film and can be used for painting an object such as a vehicle. Multilayer coating film comprises a glossy layer which contains a glossy material and is directly or indirectly formed on the surface of the coating application object, and the colored layer, which is semitransparent, contains a warm color tone pigment and is layered on the glossy layer. Glossy layer satisfies the following conditions with respect to the Y value calibrated with the standard white plate in the XYZ colorimetric system: Y(10°) is 50 or more and 950 or less; Y(25°)=k×Y(10°) (where k denotes a coefficient) and k is 0.05 or more and 0.35 or less. Y(10°) denotes the reflected light value Y, measured at angle of 10° receiving light (angle of deviation towards light source from mirror reflection angle). Y(25°) denotes the reflected light value Y, measured at angle of 25° receiving light when the angle of incidence of light is 45° (angle with deviation by 45° from normal to surface of glossy layer). Content C of the pigment of warm color tone in the colored layer is 1 % or more by weight and 17 % or less by weight. Object with coating contains multilayer coating film. 
     EFFECT: improved brightness variation properties when observing a change in the viewing angle of the multilayer coating film, in which the warm color tone is manifested through the glossy layer and the semitransparent colored layer, thereby achieving a color with a metallic texture having a high-quality color tone.
