What is claimed is: 1. A laminate comprising: an ionomer layer and a tie-layer comprising a (co)extrudable tie resin (CTR), wherein the CTR consists essentially of a copolymer of one or more C2-C10 α-olefins and one or more ethylenically copolymerizable amine-containing monomers, the copolymer

What is claimed is: 1. A laminate comprising: an ionomer layer and a tie-layer comprising a (co)extrudable tie resin (CTR), wherein the CTR consists essentially of a copolymer of one or more C2-C10 α-olefins and one or more ethylenically copolymerizable amine-containing monomers, the copolymer having amine groups that may be represented by the general formula: where each R is independently H or a C1 to C10 hydrocarbon and R' is a bond or a C1 to C10 hydrocarbon. 2. The laminate of claim 1, wherein R is H and R' is a bond. 3. The laminate of claim 1, wherein the C2-C10 α-olefins are ethylene and/or propylene. 4. The laminate of claim 1, wherein the ionomer layer comprises a first ionomer layer and a second ionomer layer. 5. The laminate of claim 4, wherein the first ionomer layer or the second ionomer layer is pigmented, natural, or clear. 6. The laminate of claim 1, further comprising a backing layer. 7. A composite comprising: an ionomer layer; a tie-layer comprising a (co)extrudable tie resin (CTR); and a substrate, wherein the CTR consists essentially of a copolymer of one or more C2-C10 α-olefins and one or more ethylenically copolymerizable amine-containing monomers, the copolymer having amine groups that may be represented by the general formula: where each R is independently H or a C1 to C10 hydrocarbon and R' is a bond or a C1 to C10 hydrocarbon. 8. The composite of claim 7, wherein R is H and R' is a bond. 9. The composite of claim 7, wherein the C2-C10 α-olefins are ethylene and/or propylene. 10. The composite of claim 7, wherein the ionomer layer comprises a first ionomer layer and a second ionomer layer. 11. The composite of claim 10, wherein the first ionomer layer or the second ionomer layer is pigmented, natural, or clear. 12. The composite of claim 7, wherein the ionomer layer comprises a zinc-neutralized ionomer or a sodium-neutralized ionomer. 13. The composite of claim 7, further comprising a backing layer. 14. The composite of claim 7, wherein the thickness of the composite article is from 200 μm to 6 mm. 15. The composite of claim 7, wherein the substrate material is selected from EPDM (ethylene-propylene-diene monomer), EP (ethylene-propylene rubber), acrylonitrile-butadiene-styrene terpolymer, acetal polymer, acrylic polymers, cellulosics, fluoroplastics, nylon and other polyamides, polyamide-imide, polycarbonate, polyester, polyetheretherketone, polyetherimide, polyethylene, polyimide, polyphenylene, polyphenylene sulfide, plastomer, polypropylene, polypropylene impact copolymers, polystyrene, polysulfone, polyurethane, polyvinyl chloride, and foams of such materials, as well as blends of these materials. 16. The composite of claim 7, wherein the substrate is a polyolefin selected from polyethylene polymers, polyethylene copolymers, polypropylene polymers, polypropylene copolymers, polypropylene impact copolymer and a blend of polypropylene impact copolymer and ethylene plastomer, and mixtures thereof. 17. The composite article of claim 7, wherein the laminate is thermoformed. 18. A composite article formed by the method comprising: (a) providing a laminate comprising an ionomer layer and a tie-layer comprising a (co)extrudable tie resin (CTR); (b) forming a shape from the laminate, resulting in a shaped laminate; and (c) securing a substrate material to the shaped laminate, wherein the CTR consists essentially of a copolymer of one or more C2-C10 α-olefins and one or more ethylenically copolymerizable amine-containing monomers, the copolymer having amine groups that may be represented by the general formula: where each R is independently H or a C1 to C10 hydrocarbon and R' is a bond or a C1 to C10 hydrocarbon. 19.
