Abstract
A laminate comprising a sheet of the polycarbonate or polyacrylate resin in face-to-face contact with a sheet of polyvinyl butyral plasticized with an effective amount of a plasticizer which is at least a partial ester formed by reaction of an alcohol having from 2 to 4 hydroxyl groups and a C.sub.16 -C.sub.20 unsaturated fatty acid having a hydroxyl group attached to the acid molecule.
Claims8
A laminate comprising at least one sheet of thermoplastic resin selected from the group consisting of polycarbonates and polyacrylates laminated to a sheet of polyvinyl butyral plasticized with an effective amount of a plasticizer which is at least a partial ester formed by the reaction of an alcohol having from 2 to 4 hydroxyl groups and a C.sub.16 to C.sub.20 unsaturated fatty acid having a hydroxyl group attached to the acid molecule.
A laminate comprising a sheet of a polycarbonate resin laminated to a sheet of a polyvinyl butyral resin plasticized with from 20 to 50 parts per hundred, based on the polyvinyl butyral resin weight, of castor oil.
A security glazing unit comprising, in laminated sequence, sheets of glass, polyvinyl butyral, polycarbonate, polyvinylbutyral and glass wherein the polyvinyl butyral layers are plasticized with an effective amount of castor oil.
A glazing unit comprising, in laminated sequence, sheets of glass, polyvinyl butyral plasticized with an effective amount of castor oil, and a polycarbonate resin wherein the exposed surface of the polycarbonate resin sheet is provided with an abrasion-resistant coating.
A glazing unit comprising a polyvinyl butyral sheet plasticized with an effective amount of castor oil and laminated between two sheets of a polycarbonate resin.
