Laminated safety glass
First Claim
1. A transparent laminated article free of an adhesive composition comprising:
- a lamina consisting essentially of an extruded ionomer resin film, said ionomer resin film being water insoluble and selected from the group of ionomer resins which are ionically cross-linked copolymers prepared from ethylene or an alpha-olefin and carboxylic acid monomers;
one sheet of primed or unprimed glass laminated directly onto one surface of said lamina, and a second sheet laminated directly onto said lamina on the surface thereof opposite said sheet of glass, whereby said lamina is bonded between said sheet of glass and said second sheet without an intermediate adhesive layer, said second sheet being selected from the group of plastic materials consisting of polycarbonate and acrylic.

Abstract
Laminated articles, particularly safety glass, are disclosed which comprise a lamina of ionomer film laminated to a sheet of glass. The ionomer resin film is preferably an ionically cross-linked resin prepared from ethylene or an alpha-olefin and carboxylic acid monomers. In particular, ethylene and acrylic acid monomers are preferred but other monomers are also disclosed. The laminated articles may also comprise a sheet of polycarbonate laminated to the ionomer resin film opposite the glass. The laminated articles may further comprise an ionomer resin film sandwiched between two sheets of glass. The laminated articles may still further comprise a sheet of polycarbonate or other plastic material or metal sandwiched between sheets of ionomer resin film, which are in turn sandwiched between sheets of glass.
