The present embodiment relates to a resin layer including a bonding layer, a light-transmitting laminate, a vehicle, and the like, the resin layer including at least one bonding layer, the bonding layer including a polyvinyl acetal resin, a plasticizer, and a bonding force adjusting agent, the surface of the bonding layer including a portion having a moisture incompatibility of 3.5 to 10, and the surface of the bonding layer including a portion having a moisture incompatibility of 3.5 to 10. The moisture incompatibility is calculated by the following formula 1: (Formula 1) moisture incompatibility = non-polarity/polarity. In formula 1, the non-polarity is the non-polarity in the surface free energy of the bonding layer, and the polarity is the polarity in the surface free energy of the bonding layer. The present embodiment may have excellent storage moisture resistance, less yellowness change, and excellent bonding force adjusting effect by adjusting moisture incompatibility.
本实施方式涉及包含接合层的树脂层、透光层叠体及交通工具等,其包括至少一层接合层,上述接合层含有聚乙烯醇缩醛树脂、增塑剂及接合力调节剂,上述接合层的表面包括具有3.5至10的水分不相容性的部分,上述水分不相容性由下述式1进行计算:[式1]水分不相容性=非极性度/极性度。在上述式1中,上述非极性度为上述接合层的表面自由能中的非极性度,上述极性度为上述接合层的表面自由能中的极性度。本实施方式可以通过调节水分不相容性来具有优异的保存耐湿性、较少的黄度变化、优异的接合力调节效果。
