The invention relates to a security document (30″), to a method for producing a security document (30″), and to a method for producing an individualized security document (30″). The security document (30″) has a carrier substrate (1) with a carrier layer (10) and a thermosensitive coating (11) which can be caused to change color by the action of heat, in particular by means of a thermal print head (911). The security document (30″) further has a film element (2), which is transparent at least in areas and which has at least one decorative layer (24, 25) with at least one optical security feature (51, 52), and an adhesive layer (3). The adhesive layer (3) is arranged between the film element (2) and the carrier substrate (1). The thermosensitive coating (11) is arranged between the adhesive layer (3) and the carrier layer (10). The film element (2) covers the thermosensitive coating (11) at least in areas when viewed perpendicularly to the plane spanned by the upper side of the carrier substrate.
