Abstract
The present invention provides a reinforced glass laminate, comprising a non-hydrophilic synthetic resin, at least one surface of which has been rendered hydrophilic by bonding thereon a layer of a hydrophilic material, a layer of hydrophilic synthetic resin being bonded to said layer of hydrophilic material and a layer of glass being bonded to said layer of hydrophilic synthetic resin. The present invention also provides a process for producing a reinforced glass laminate, wherein a non-hydrophilic synthetic resin is coated with a solution capable of forming a layer of a hydrophilic material thereon, the solvent medium is then removed, a hydrophilic synthetic resin is placed on the layer of hydrophilic material and glass is then placed on the hydrophilic synthetic resin, whereafter bonding together of the layers is achieved either by applying an increased pressure at an elevated temperature or by heating under reduced pressure.
