    摘要: A unitary method of making a printed magnetic assembly is disclosed, the printed magnetic assembly comprising at least one magnetic layer and at least one printable substrate layer in the form of a sheet or roll, the method comprising the steps of: a) providing a molten magnetic hot melt composition comprising about 70 wt-% to about 95 wt-% of at least one magnetic material and about 5 wt-% to about 30 wt-% of at least one thermoplastic binder; b) directly extruding the magnetic composition at an elevated temperature when it is pliable onto the printable substrate layer with a single screw or double screw extruder to form at least one discrete thin magnetic layer on the printable substrate to form a layered sheet or roll; d) feeding the roll or sheet through a printing press at a speed of about 60 feet/minute to about 1000 feet/minute; e) printing on the printable substrate layer using at least one method selected from the group consisting flexo, gravure, digital and screen printing; and f) permanently magnetizing the magnetic layer, and articles made thereby.
