<p>A laminated glass comprises a tempered first glass sheet, in which by breaking the glass sheet at one point, cracks spread spontaneously so that a crack-network is formed, and a second glass sheet. The second glass sheet has a lower strength than the first glass sheet, or such a thickness and a strength that the second glass sheet can be easily broken on the side of the first glass. Such a laminated glass can reduce the difficulty in escaping from the interior of an automobile sunk in water or the like. <IMAGE></p> |
