Abstract
A transfer foil comprises a film-like substrate, and a layered transfer body having a pair of opposing surfaces and having an adhesion layer. A first surface of the pair of opposing surfaces is in contact with the substrate so as to be peelable from the substrate, and the adhesion layer is provided so as to include a second surface of the pair of opposing surfaces. The adhesion layer is a composite, and comprises a plurality of resin particles respectively comprising a first resin, and a layered base material comprising a second resin and filling gaps between the resin particles. The melting point of the second resin is lower than the melting point of the first resin. The transfer foil uses an adhesion layer of a composite of two incompatible resins that have different characteristics, such as melting point and crystallinity.
