| 摘要 |
The present invention provides laminated glass obtained by integrally bonding glass sheets through an adhesive, the adhesive comprising a hydrogenated block copolymer [3] obtained by introducing an alkoxysilyl group into a hydrogenated block copolymer [2] that is obtained by hydrogenating 90% or more of unsaturated bonds of a block copolymer [1] that comprises at least two polymer blocks [A] and at least one polymer block [B], the polymer block [A] comprising a repeating unit derived from an aromatic vinyl compound as a main component, the polymer block [B] comprising a repeating unit derived from a linear conjugated diene compound as a main component, and a ratio (wA:wB) of a weight fraction wA of the polymer block [A] in the block copolymer [1] to a weight fraction wB of the polymer block [B] in the block copolymer [1] being 30:70 to 60:40. The present invention provides laminated glass employing a block copolymer hydrogenation product comprising an alkoxysilyl group, which is easy to handle, and excellent light-fastness, heat resistance, moisture resistance and transparency. |
