| Zusammenfassung: | The present invention is to provide a laser photothermal transfer film with improved transfer characteristics by using bismaleimide resin with a high expansion rate as a binder. The laser photothermal transfer film comprises: a base film; a light-to-heat conversion layer; and an adhesive layer, which are laminated in the order. The photothermal transfer layer is a laser photothermal transfer film that is solid at room temperature and contains: an infrared light absorber represented by general formula 1; and a bismaleimide resin represented by general formula 3 and/or 4. [Formula 1] In general formula 1, p is 1 or 2, and each of R_1 to R_8 is independently substituted or unsubstituted straight-chain or branched alkyl group having 1 to 10 carbon atoms, and X^- is a fluoroalkyl phosphate anion represented by general formula 2.
