Abstract
Laminated pane, comprising at least one glass sheet, and at least one film of plastics material. Between the film of plastics material and the glass sheet there Is disposed an adhesive film of a material having the property of an adhesion to the glas. The adhesive film is selected so that it adheres more strongly to the glass than to the plastics material.
Claims20
A laminated pane including at least one glass sheet and at least one film of plastics material comprising PVC and having a transparency which is stable with respect to aging and weathering and having an energy absorption suitable for a safety pane, wherein there is disposed an adhesive film between the glass sheet and film of plastics material, said adhesive film having a greater adhesion to the glass than to the film of plastics material, and wherein said adhesive film comprises a terpolymer comprised of ethylene, either vinyl acetate or acrylic ester, and maleic anhydride.
A laminated pane comprising at least one glass sheet, at least one adhesive film, and at least one film of plastics material, wherein said adhesive film is disposed between said glass sheet and said film of plastics material, and wherein said adhesive film has a greater adhesion to the glass than to the film of plastics material and comprises a terpolymer of ethylene, vinyl acetate, and maleic anhydride, the maleic anhydride being present in the terpolymer in the amount of from about 0.1 to 5% by weight based on the terpolymer and wherein said plastics material has a transparency which is stable with respect to aging and weathering and has an energy absorption suitable for a safety pane.
A laminated pane including a composite between two glass sheets, wherein the composite comprises a plastic sheet comprising PVC and having a transparency which is stable with respect to aging and weathering and having an energy absorption suitable for a safety pane disposed between two adhesive films, said adhesive films having a greater adhesion to the glass than to the film of plastics material, wherein each of said adhesive films are composed of a terpolymer including 0.1 to 5% of maleic anhydride, by weight based on the terpolymer.
A laminated pane including a glass sheet and sheet of rigid plastics material disposed on opposite sides of a composite structure, said composite structure comprising at least one adhesive film and a film comprising a plastics material, said plastics material having a transparency stable with respect to aging and weathering, and having an energy absorption suitable for a safety pane, and wherein said adhesive is disposed between said glass sheet and said film comprising a plastics material and said adhesive has a greater adhesion to the glass than to the film of plastics material and comprises a terpolymer including 0.1 to 5% maleic anhydride by weight based on the terpolymer.
