The present invention provides a glass laminate, characterized in that glass sheets are adhered as one unit by interposing between the glass sheets a binder that comprises a block copolymer hydrogenation product [3] wherein alkoxysilyl groups have been introduced to a block copolymer hydrogenation product [2] obtained by hydrogenation of 90% or more of all unsaturated bonds of block copolymer [1], which is formed from at least two polymer blocks [A] the primary component of which is repeating units derived from an aromatic vinyl compound and at least one polymer block [B] the primary component of which is repeating units derived from a cyclic conjugated diene compound, and has a ratio of (wA) and (wB) (wA:wB) between 30:70 and 60:40 when the weight percentage of whole polymer blocks [A] in the entire block copolymer is (wA) and the weight percentage of whole polymer blocks [B] in the entire block copolymer is (wB). The present invention provides a glass laminate employing a block copolymer hydrogenation product comprising alkoxysilyl groups, which is easy to handle, and has excellent light-fastness, heat resistance, moisture resistance and transparency. |
