PROBLEM TO BE SOLVED: To provide a coating film producing method capable of easily producing a transparent coating film having different composition on the surface of the coating film and the back side thereof, and formed of several kinds of resin, without using the several kinds of resin as raw materials.SOLUTION: A method is provided for producing a coating film in which the composition in the thickness direction of the coating film is changed continuously. The method includes: using a coating film forming material containing a polymeric raw material and raw material monomer, as the coating film forming material for forming the coating film; irradiating a formed coating with an active energy ray, after applying the coating film forming material to a substrate; and polymerizing the raw material monomer contained in the coating film forming material. |
