Abstract

A rear face side substrate for a thermal transfer image-receiving sheet has a first rear face side layer, a second rear face side layer, and a third rear face side layer layered in this order, wherein the first rear face side layer comprises a propylene-based polymer composition A containing at least a propylene-based polymer, the second rear face side layer comprises a propylene-based polymer composition B containing at least a propylene polymer, an antistatic agent and a masking agent, and the third rear face side layer comprises a propylene-based polymer composition (C) containing at least a propylene-based polymer, a three-dimensional center surface average roughness (SRa) of the third rear face side layer being in the range of 0.10 μm to 1.50 μm, and the first rear face side layer, the second rear face side layer and the third rear face side layer being biaxially oriented.
