    • A composite film useful for image supporting media, including: a first layer containing a thermoplastic polymer and optionally containing a whitening agent; a second layer containing a thermoplastic polymer and a whitening agent; a third layer containing a thermoplastic polymer and a cavitating agent, wherein the third layer is a cavitated layer; optionally a fourth layer containing a thermoplastic polymer and optionally a whitening agent; and optionally a fifth layer containing a thermoplastic polymer and optionally a whitening agent; wherein the second layer is between the first layer and the third layer, the third layer is between the second layer and the optional fourth layer, and the optional fourth layer is between the third layer and the optional fifth layer. Embodiments may have the advantage(s) of improved outer surface characteristics, compressibility, thermal insulation, whiteness, and/or stiffness.
    • 一种用于图像支持介质的复合膜,包括:含有热塑性聚合物和任选地含有增白剂的第一层; 含有热塑性聚合物和增白剂的第二层; 含有热塑性聚合物和气蚀剂的第三层,其中所述第三层是空化层; 任选的含有热塑性聚合物和任选的增白剂的第四层; 和任选地含有热塑性聚合物和任选的增白剂的第五层; 其中所述第二层位于所述第一层和所述第三层之间,所述第三层位于所述第二层和所述第四层之间,并且所述第四层位于所述第三层和所述第五层之间。 实施例可以具有改进的外表面特性,可压缩性,绝热性,白度和/或刚度的优点。
