PROBLEM TO BE SOLVED: To provide a magnetic composite film excellent in terms of curling resistance, possessing, on both flexible surfaces thereof, printable layers, and devoid of a magnetic suction force difference on both surfaces.SOLUTION: A magnetic composite film B2 possessing printable layers on both surfaces thereof and obtained by pasting, via an adhesive or a hot press, the respective magnetic layer surfaces of precursors each formed by coating a magnetic layer 2 on the rear surface of a water-resistant thin layer substrate 1 possessing a printable layer on the front surface thereof in a state where materialistic and morphological symmetries are realized in relation to the center line of a cross section thereof along a direction orthogonal to the thickness direction thereof is provided. It accordingly becomes to realize subsidiary merits of improving magnetic properties and, in the case of a hard magnetic composite film, of equalizing magnetic suction forces on the front and rear surfaces thereof. |
