The present invention aims to provide a laminate for a laminated glass which is used as a head-up display (HUD) and is not deteriorated even if exposed to light, and with which a laminated glass having excellent impact resistance can be prepared.
The present invention pertains to a laminate for a laminated glass, wherein an interlayer film for a laminated glass and a retardation element sandwiched between adhesive layers are laminated, the interlayer film for a laminated glass contains a thermoplastic resin and an ultraviolet absorber, the interlayer film for a laminated glass contains, as the ultraviolet absorber, a benzotriazole compound or a benzophenone compound, and at least one compound selected from the group consisting of a malonic ester compound, an oxanilide compound and a triazine compound, the sum of the contents of the malonic ester compound, the oxanilide compound and the triazine compound is 0.8 parts by weight or more and the sum of the contents of the benzotriazole compound or the benzophenone compound is 0.8 parts by weight or more with respect to 100 parts by weight of the thermoplastic resin and the adhesive layer contains an adhesive having a glass transition temperature of -20°C or lower.
本发明旨在提供一种用于夹层玻璃的层压板,该层压板可用作平视显示器(HUD),即使暴露在光线下也不会变质,并且可以制备具有优异抗冲击性的夹层玻璃。
本发明涉及一种夹层玻璃用层压板,其中夹层玻璃用中间膜和夹在粘合剂层之间的延缓元件被层压,夹层玻璃用中间膜包含热塑性树脂和紫外线吸收剂,夹层玻璃用中间膜包含、作为紫外线吸收剂,含有苯并三唑化合物或二苯甲酮化合物,以及至少一种从丙二酸酯化合物、草酰苯胺化合物和三嗪化合物组成的组中选出的化合物,丙二酸酯化合物、草酰苯胺化合物和三嗪化合物的含量之和为 0.8 份(重量比)或更多,苯并三唑化合物或二苯甲酮化合物的含量总和为 0.8 份(重量比)或更多(相对于 100 份(重量比)热塑性树脂),且粘合剂层含有玻璃化转变温度为 -20°C 或更低的粘合剂。
