The purpose of the present invention is to provide a transfer sheet capable of providing hard coat properties and excellent weather resistance to a resin molded article such as organic glass. The transfer sheet has, in order, a base material film for mold release, a hard coat layer, a primer layer, and an adhesive layer. The weather resistance and adhesiveness of the hard coat layer and the primer layer are improved and hard coat properties and excellent weather resistance can be provided to a resin molded article being the transfer object, as a result of: the hard coat layer being formed from a cured product of a resin composition including a curable resin; and the primer layer being formed from a binder resin including a polyurethane having a mass-average molecular weight of 40,000-100,000 and including 1-30% by mass of an acrylic component.
本发明的目的是提供一种能够为有机玻璃等树脂模制品提供硬涂层特性和优异耐候性的转印膜。这种转印片依次具有用于脱模的基材薄膜、硬涂层、底漆层和粘合剂层。由于硬涂层由包括可固化树脂在内的树脂组合物的固化产物形成,且底涂层由包括聚氨酯在内的粘合剂树脂形成,该聚氨酯的质量平均分子量为 40,000-100,000 且包括 1-30% (质量百分比)的丙烯酸成分,因此硬涂层和底涂层的耐候性和粘合性得到改善,可为作为转移物体的树脂成型品提供硬涂层特性和优异的耐候性。
