<P>PROBLEM TO BE SOLVED: To provide high-safety laminated glass which has shock resistance needed for laminated glass and generates a small amount of small scattering glass fragments in breakage. <P>SOLUTION: The laminated glass 10 has a structure wherein seven glass sheets 20 and six PVB resin layers 30 are alternately laid. A laminated zone from one light-transmissive surface 10a to 4.0 mm is composed of two 0.7 mm thick glass layers consisting of two glass sheets 20, one 0.8 mm thick glass layer consisting of the portion 20c of one 1.5 mm thick glass sheet 20 located in the laminated zone, and two adhesion layers 30 having a thickness of 1.3 mm and 0.5 mm, respectively, which are interposed between these glass layers and adhere to the glass layers. The laminated zone from the opposite light-transmissive surface 10b to 4.0 mm has the same laminate structure as in the above laminated zone. <P>COPYRIGHT: (C)2009,JPO&INPIT |
