ABSTRACT:
A component for a laminated window, the component comprising a glass sheet having an etched hydrated surface and a protective layer of plastics material covering the etched surface, the protective layer being selected so as to be bondable to a plastics interlayer material. The invention also provides a laminated window including a first ply comprising a glass sheet having an etched hydrated surface and a protective layer of plastics material covering the etched surface and a second ply to which the first ply is bonded by a plastics interlayer, the material of the interlayer and of the protective layer being selected so as to be bondable together. The present invention further provides a method of producing a pre-product glass sheet having improved bending strength.
