To provide a lightweight laminated glazing for use in a vehicle, a method of making the same, and a glass sheet suitable to be incorporated in the laminated glazing.SOLUTION: A laminated glazing 51 comprises a first ply of glazing material and a second ply of glazing material joined by at least one ply of adhesive interlayer material. The first ply of glazing material comprises a sheet of glass having a first composition, and the second ply of glazing material comprises a second composition different from the first composition. The laminated glazing has (i) a peripheral region extending around a periphery of the laminated glazing, the laminated glazing having a surface compression stress in the peripheral region and (ii) an edge compression, where the magnitude of edge compression is greater than the magnitude of the surface compression stress in the peripheral region.SELECTED DRAWING: Figure 10

    【課題】車両に使用するための軽量積層ガラス、その作製方法、及び該積層ガラスに組み込まれるのに適したガラスシートの提供。【解決手段】粘着性中間層材料の少なくとも1つの層によって接合された、板ガラス材料の第1の層と、板ガラス材料の第2の層とを含む、積層ガラス51。板ガラス材料の第1の層は、第1の組成物を有するガラスシートを含み、板ガラス材料の第2の層は、第1の組成物とは異なる第2の組成物を含む。積層ガラスは、(i)積層ガラスの周辺部の周りに延在する周辺領域を有し、この積層ガラスは、周辺領域内に表面圧縮応力及び(ii)縁部圧縮を有し、縁部圧縮の大きさは、周辺領域の表面圧縮応力の大きさよりも大きい。【選択図】図10
