In addition, the architectural finishing material is manufactured in a state of being laminated from the bottom, such as a film, a paint layer, and a base sheet.

Therefore, the number of manufacturing steps in the method for manufacturing a finishing material for building can be reduced, and the labor for the operation can be saved. In addition, it is possible to manufacture an architectural finishing material without requiring a press which is one of the conventional manufacturing processes. In addition, when heating, air bubbles generated from the paint layer can be removed through the base sheet.

[0013] In the method for producing a finishing material for building according to the second aspect, printing inks and paints of the same color are used. For this reason, even if the surface of the architectural finishing material is scratched, the color of the paint layer of the same system as that of the printing ink appears from the scratched portion, and a kind of pattern is formed, so that the scratch becomes inconspicuous.

According to a third aspect of the present invention, the film is partially printed with the printing ink. Then, what is partially printed on the film is transferred onto the paint layer, and a pattern or the like is formed on the paint layer.

Therefore, the surface of the architectural finishing material can be given a three-dimensional effect when viewed from the outside, and the texture and decorativeness can be improved.
