Abstract
The invention provides a transparent and tenacious coating film using an inorganic paint composition prepared by adding a borate salt into an alkali metal silicate, and further mixing thereto lepidoblastic transparent silica with a thickness of 0.01 to 0.5 μm and a surface diameter of 2 to 5 μm. The alkali metal silicate is solidified with metal ions issued from the borate salt to form a coating film, which contains a glass formed by solidifying dissolved boric acid in the coating film. The coating film can be made tenacious without impairing transparency by dispersing many flakes of transparent silica as laminated layers.
