Patent ID: 7128798

Claim:
A unitary process of forming a magnetic assembly having at least one magnetic layer having dimensions of thickness, width and length, and at least one printable substrate layer having dimensions of thickness, width and length, comprising the steps of: a) providing a magnetic hot melt composition at an elevated temperature with an extruder, said magnetic hot melt composition comprising about 75 wt-% to about 95 wt-% of at least one magnetic material and about 5 wt-% to about 25 wt-% of at least one thermoplastic polymer; b) directly applying said magnetic hot melt composition with a slot die head at an elevated temperature when it is pliable to a printable substrate layer to form a magnetic layer having a thickness of about 50 microns to about 305 microns, the printable substrate layer formed of paper, paper products or paste board; and c) subjecting said magnetic assembly to a strong magnetic field sufficient to result in a permanent magnetic effect in the assembly.
