    Abstract: The purpose is to provide a protective layer transfer sheet and an intermediate transfer medium, in which the protective layer has excellent foil tearing property during transfer and in which sufficient durability can be imparted to the thermally transferred image.The above problem is solved by a protective layer transfer sheet in which a transferable protective layer (20) is provided on one surface of a substrate (1) so as to be peelable from the substrate (1), wherein the transferable protective layer (20) has a layered structure in which a first protective layer (3A), and a second protective layer (3B) which is in contact directly with the first protective layer (3A), are provided in this order from the substrate (1); the first protective layer contains an epoxy-cured resin in which a reactive resin having a functional group capable of reacting with an epoxy group and having a glass transition temperature (Tg) of not less than 60° C. is reacted with and cured by an epoxy curing agent; and the second protective layer (3B) contains a polyester resin having a number-average molecular weight (Mn) of not less than 8000 and a glass transition temperature (Tg) of not less than 45° C.

    Abstract translation: 其目的是提供保护层转印片和中间转印介质，其中保护层在转印期间具有优异的箔撕裂性，并且可以赋予热转印图像足够的耐久性。 上述问题是通过保护层转印片来解决的，其中可转移保护层（20）设置在基板（1）的一个表面上以便从基板（1）剥离，其中可转印保护层（20） ）具有从基板（1）依次设置有与第一保护层（3A）直接接触的第一保护层（3A）和第二保护层（3B）的层叠结构。 第一保护层含有环氧固化树脂，其中具有能够与环氧基反应并具有不低于60℃的玻璃化转变温度（Tg）的官能团的反应性树脂与其反应并使其固化 环氧固化剂; 第二保护层（3B）含有数均分子量（Mn）为8000以上且玻璃化转变温度（Tg）为45℃以上的聚酯树脂。
