    摘要: 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.
