Patent ID: 7611773

Claim:
A laminated glass comprising at least two glass sheets and at least one resin layer therebetween, wherein the at least two glass sheets includes at least one glass sheet comprising a glass composition comprising, in % by weight, 65 to 74% of SiO 2 ; 0 to 5% of B 2 O 3 ; 1.9 to 2.5% of Al 2 O 3 ; 1.0 to 3.0% of MgO; 5 to 10% of CaO; 0 to 10% of SrO; 0 to 10% of BaO; 0 to 5% of Li 2 O; 13 to 17% of Na 2 O; 0.5 to 5% of K 2 O; 0 to 0.40% of TiO 2 ; and 0.3 to 2.0% of total iron oxide in terms of Fe 2 O 3 (T-Fe 2 O 3 ), in which the sum of MgO, CaO, SrO and BaO is 10 to 15%, and the sum of Li 2 O, Na 2 O and K 2 O is 14 to 20%, wherein, at a thickness of 2.1 mm, the glass composition has a visible light transmittance of 80% or more as measured with the CIE Standard illuminant A and a total solar energy transmittance of not more than 62%, and the laminated glass has a visible light transmittance of 69% or more as measured with the CIE Standard illuminant A and a total solar energy transmittance of not more than 45%.
