Classification: CPC B  Y | IPC B

Claim 12:
13. A method of making a flexible magnetic sheet of claim 1 comprising at least three (3) continuous layers extending to edges of the flexible magnetic sheet, the method comprising:
providing a magnetizable layer, the magnetizable layer comprising at least one magnetizable component and at least one binder, the magnetizable layer is magnetizable so to be useful in magnetically adhering to a magnetically receptive surface;
providing an opaque white or colored writeable outer layer located on one side of the flexible magnetic sheet;
applying adhesive to the writeable outer layer to form an adhesive layer on the writeable outer layer, the adhesive layer having a thickness of about 0.6 mil to about 1.5 mil;
joining the adhesive layer of the writeable outer layer with the magnetizable layer; and curing the adhesive layer when located between the magnetizable layer and writeable outer layer,
wherein the cured adhesive layer is resistant to transfer from the flexible magnetic sheet to cutting blades during cutting of the flexible magnetic sheet,
wherein the flexible magnetic sheet is resistant to delamination on exposure to direct sunlight.
