<p>Provided are a building board that exhibits high weathering performance and that has an inkjet coating film unaffected by the drying state of a base coating film, and a coating method for the 5 building board. In the building board, a base coating film, an inkjet coating film and a clear coating film are sequentially formed on a surface of an inorganic board; the inkjet coating film is a cured product of a UV-curable ink; and the clear coating film contains 0.1 to 10.0 wt% of a light stabilizer and/or ultraviolet absorbent. 10 A method of producing a building board includes the steps of: implementing base coating onto a surface of an inorganic board; performing inkjet coating by coating a UV-curable ink onto the surface of the base-coated inorganic board and curing the UV-curable ink through irradiation of UV rays; and performing clear 15 coating by applying a clear coating material containing 0.1 to 10.0 wt%, on solids basis, of a light stabilizer and/or ultraviolet absorbent, onto the surface of the inkjet-coated inorganic board.</p> |
