Abstract
A process of making a magnetic assembly having at least one magnetic layer and at least one printable substrate layer including the steps of providing a magnetic 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, forming the magnetic composition into a magnetic layer, and directly applying the magnetic composition at an elevated temperature in molten form to a printable substrate layer, and to the magnetic composition and any articles made therefrom.
Claims
exact text as granted — not AI-modified1 - 60 . (canceled)
61 . A note pad, the note pad comprising a plurality of sheet articles, each sheet article comprising:
at least one printable substrate layer which is paper; and at least one magnetic layer disposed on the at least one printable substrate layer, the magnetic layer comprising a magnetic hot melt composition, the magnetic hot melt composition comprising about 75 wt-% to about 95 wt-% of a magnetic material and about 5 wt-% to about 25 wt-% of a thermoplastic hot binder, the magnetic layer has equivalent dimensions of length and width to said substrate layer; and wherein; the sheet articles are stacked into a pad and bound at one end with an adhesive composition.
62 . The note pad of claim 61 wherein said sheet articles are bound into a pad using a perfect binding wherein the adhesive is applied to an edge of the stacked sheets.
63 . The note pad of claim 61 wherein said thermoplastic binder is selected from copolymers of ethylene and vinyl acetate and mixtures thereof.
64 . The note pad of claim 61 wherein said magnetic hot melt composition comprises about 80 wt-% to about 95 wt-% of said at least one magnetic material and about 5 wt-% to about 20 wt-% of said at least one thermoplastic binder.
65 . The note pad of claim 61 wherein said magnetic hot melt composition comprises about 85 wt-% to about 95 wt-% of said at least one magnetic material and about 5 wt-% to about 15 wt-% of said at least one thermoplastic binder.
66 . The note pad of claim 61 wherein said magnetic layer has a thickness of about 50μ to about 510μ thick.
67 . The note pad of claim 61 wherein said magnetic layer as a thickness of about 50μ to about 305μ.Cited by (0)
