Abstract
A laminated glass for vehicles comprising at least two single glass sheets which are laminated through at least one interlayer, wherein an outermost single glass sheet in a laminate comprising at least two single glass sheets is an aluminosilicate glass containing lithia (Li.sub.2 O). The laminated glass is suitable as the countermeasure of flying stones when applied to windows of vehicles. The aluminosilicate glass sheet is preferably obtained by a float method, and it is also preferably chemically tempered by ion exchange.

A laminated glass for vehicles comprising at least two single glass sheets which are laminated through at least one interlayer, wherein an outermost single glass sheet in a laminate comprising at least two single glass sheets is an aluminosilicate glass containing lithia (Li.sub.2 O), wherein said aluminosilicate glass containing lithia comprises, in % by weight:
- 58 to 66% SiO.sub.2 ;
- 13 to 19% Al.sub.2 O.sub.3 ;
- 3 to 4.5% Li.sub.2 O;
- 6 to 13% Na.sub.2 O;
- 0 to 5% K.sub.2 O,
- with the proviso that Li.sub.2 O+Na.sub.2 O+K.sub.2 O=10 to 18%:
- 0to 3.5% MgO;
- 1 to 7% CaO;
- 0 to 2% SrO;
- 0 to 2% BaO,
- with the proviso that MgO+CaO+SrO+BaO=2 to 10%:
