## Abstract

Printable magnetic receptive composite sheets are made by calendering a thin layer of a magnetic composition and bonding it to a top printable layer on one or both sides of the magnetic layer wherein the calendered layer has a thickness up to 10 mils.

## Claims

### Claim 1

A printable magnetic receptive composite sheet comprising:
a calendered magnetic layer containing a thermoplastic binder and a magnetic material having a front side and a back side, and
a printable top layer bonded to at least one of said sides, wherein said calendered magnetic layer has a thickness up to 10 mils.

### Claim 2 (depends on 1)

The sheet of claim 1 wherein said calendered magnetic layer has a thickness from about 6 to 10 mils.

### Claim 3 (depends on 1)

The sheet of claim 1 wherein said printable top layer is a substrate selected from the group of a polymeric material, cotton, textile or a paper product.

### Claim 4 (depends on 3)

The sheet of claim 3 having an indefinite length and a width of up to about 60 inches with a total thickness of up to about 20 mils.

### Claim 5 (depends on 3)

The sheet of claim 3 wherein the polymeric material is a thermoplastic polymer.

### Claim 6 (depends on 5)

The sheet of claim 5 wherein said polymer is a polyester or PVC.

### Claim 7 (depends on 6)

The sheet of claim 6 wherein the polyester is polyethylene terephthalate.

### Claim 8 (depends on 3)

The sheet of claim 3 wherein said printable top layer has a surface with printable coating deposited thereon.

### Claim 9 (depends on 8)

The sheet of claim 8 wherein said printable coating has a silicon dioxide or a titanium oxide pigment dispersed in a polymeric binder selected from the group of a water-based polyurethane, water-based ethylene vinyl acetate polymer and polyacrylic emulsion.

### Claim 10 (depends on 1)

The sheet of claim 1 wherein the said thermoplastic binder is a polymer with a monomeric group of an olefin, vinyl halide and vinyl acetate, and copolymers thereof.

### Claim 11 (depends on 1)

The sheet of claim 1 wherein the thermoplastic binder is a chlorinated polyethylene, ethylene vinyl acetate, or polyolefin elastomer, and mixtures thereof.

### Claim 12 (depends on 1)

The sheet of claim 1 wherein the calendered magnetic layer is bonded to the printable top layer with the aid of an adhesive.

### Claim 13 (depends on 1)

The sheet of claim 1 wherein said calendered magnetic sheet contains an anaerobic prodegradant.

### Claim 14 (depends on 13)

The sheet of claim 13 wherein said anaerobic prodegradant is a monomeric adduct of an organotitanate or organozirconate.

### Claim 15

A method of making a printable magnetic receptive composite sheet having multiple layers with a front and a back side comprising:
calendering a thermoplastic composition containing a thermoplastic binder and a magnetic material into a continuous magnetic layer having a thickness up to 10 mils and;
laminating a printable top layer onto at least one of said magnetic layer sides.

### Claim 16 (depends on 15)

The method of claim 15 conducted at an elevated temperature for laminating the magnetic layer to said printable top layer.

### Claim 17 (depends on 15)

The method of claim 15 wherein the lamination is conducted with the aid of an adhesive selected from the group of water-based polyurethane and water-based EVA.

### Claim 18 (depends on 15)

The method of claim 15 wherein the said thermoplastic binder is a polymer having the monomeric group of an olefin, vinyl halide and vinyl acetate, and copolymers thereof.

### Claim 19 (depends on 15)

The method of claim 15 wherein said printable top layer is a substrate selected from the group of a polymeric material, cotton, textile or a paper product.

### Claim 20 (depends on 15)

The method of claim 15 wherein said printable top layer has a surface with a printable coating deposited thereon.

### Claim 21 (depends on 15)

The method of claim 15 said printable coating has a silicon dioxide or a titanium oxide pigment dispersed in a polymeric binder selected from the group of a water-based polyurethane, water-based ethylene vinyl acetate polymer and polyacrylic emulsion.
