To obtain a colored topcoat coating composition that individually and concretely specifies the source or history of a product by including an information nucleic acid and a colored topcoat coating film.
The colored topcoat coating composition comprises an information nucleic acid provided with a part having an arbitrary and known base sequence in a raw material of a colored topcoat coating. The coating composition contains 0.5-500μg of the information nucleic acid based on 100g of a resin solid content. The information nucleic acid is supported on a fine particle. The fine particle has 0.01-40μm average particle diameter. The content of the fine particle is 0.5-20% based on the resin solid content. The colored topcoat coating film is obtained by solidifying the colored topcoat coating composition and is a base coat or enamel coating film.
