Abstract
A transfer film for exterior materials which includes a release film and a transfer layer. The transfer layer includes a surface protection layer. The surface protection layer constitutes a surface layer of the transfer layer which faces the release film. The content of silicon atoms in the surface of the surface protection layer which faces the release film, the content being determined by X-ray photoelectron spectroscopy, is 3 atomic % or more and 30 atomic % or less.
