摘要: A glass laminate structure comprising an internal glass sheet, an external glass sheet, and at least one polymer interlayer intermediate the external and internal glass sheets where the polymer interlayer includes a phenol, 2-(2H-benzotriazol-2-yl)-4,6-bis(1,1-dimethylpropyl) additive, a 2-(2H-benzotriazol-2-yl)-4,6-bis(1-methyl-1-phenylethyl)phenol additive, a 2-(2H-Benzotriazol-2-yl)-6-(1-methyl-1-phenylethyl)-4-(1,1,3,3-tetramethylbutyl)phenol additive, or an hydroxyphenyl substituted benzotriazole additive without a chlorine substituent. In some embodiments, the external and/or internal glass sheets can be formed from non-chemically strengthened glass, and in other embodiments, the external and/or internal glass sheets can be formed from chemically strengthened glass. Use of such an additive can reduce or eliminate discoloration of the polymer interlayer when using high ultraviolet transmission glass sheets.
