Laminated coating film and coated article

A multilayer coating film comprising:

• a lower coating film configured to be provided on a target article, the lower coating film containing a colorant and a second constituent;
• and
• an upper coating film stacked on the lower coating film, the upper coating film containing a first constituent, wherein
• the upper coating film is stacked directly on the lower coating film,
• the first constituent contains a resin as a main ingredient, the resin containing nanoparticles that have a higher refractive index than the resin,
• the first constituent has a refractive index n1 of greater than or equal to 1.6,
• the second constituent has a refractive index n2 of less than or equal to 1.4, and
• a ratio n1/n2 of the refractive index n1 of the first constituent to the refractive index n2 of the second constituent is greater than 1 and less than or equal to 1.67.
