To provide a laminated coating film structure capable of individually and concretely specifying the origin and history of a product by using nucleic acid subjected to information processing.
A discrimination layer containing the nucleic acid subjected to information processing, which is equipped with a region having an arbitrary or known base sequence, is provided to the lower layer of a clear coating film layer. The nucleic acid subjected to information processing is added in an amount of 0.5-500 μg/m2 as the amount per the unit surface area of an article to be coated and supported on fine particles with a mean particle size of 0.01-2 μm. The fine particles are added in a ratio of 0.5-50% with respect to the surface area of the article to be coated.
